Ilsan Haengsin-dong Eye Clinic: Macular Degeneration Injections, Treatment Options, and Changes in Cost

eyessg — Wed, 23 Sep 2026 14:45:35 +0900

Hello. This is Goyang Shinsegae Eye Clinic.

One of the biggest concerns for patients diagnosed with macular degeneration is intravitreal injection treatment.

“Does the medication really have to be injected directly into the eye?”

“Will one injection be enough?”

“Is there a large difference in cost depending on the medication?”

Wet age-related macular degeneration, in particular, can cause abnormal blood vessels to develop in the central retina, potentially leading to bleeding or swelling. Depending on the condition of the retina, active treatment may therefore be necessary.

In recent years, not only have more treatment options become available, but the introduction of biosimilars has also changed the financial burden associated with treatment.

Today, we will explain why intravitreal injections may be necessary for wet macular degeneration, which medications are commonly used, why costs differ, and what has changed in recent years.

1. Why Are Injections Needed for Wet Macular Degeneration?

Macular degeneration is generally divided into two types: dry and wet.

Dry macular degeneration usually progresses more slowly and is associated with the accumulation of deposits such as drusen in the retina.

Wet macular degeneration, on the other hand, involves the growth of abnormal new blood vessels beneath or within the retina. These vessels can leak fluid or bleed.

As a result, patients may notice symptoms such as straight lines appearing distorted, blurred central vision, or a sudden decrease in visual acuity.

Intravitreal injection treatment for wet macular degeneration commonly involves medications that inhibit VEGF, or vascular endothelial growth factor, which plays an important role in the development of abnormal blood vessels.

The primary goal is to suppress the activity of these abnormal vessels and help control retinal swelling and bleeding.

2. Which Medications May Be Used?

At an eye clinic in the Ilsan area, the choice of medication is generally based on several factors, including the condition of the retina, the activity of the lesion, and how the eye has responded to previous treatment.

Commonly used medications include Avastin, ranibizumab-based medications, and aflibercept-based medications.

Each option differs in its mechanism of action, approved indications, National Health Insurance coverage criteria, and cost.

For this reason, no single medication is appropriate for every patient.

✅ Severity of Abnormal Blood Vessels and Retinal Swelling

The ophthalmologist evaluates how active the lesion is and how much swelling or leakage is present.

✅ Response to Previous Medication

The response to previously administered injections is also taken into consideration.

✅ Health Insurance Coverage

Out-of-pocket expenses may vary depending on the examination findings, previous treatment history, and whether the medication meets the criteria for insurance coverage.

Therefore, when considering injection treatment for macular degeneration, it is more important to determine which medication is appropriate for the current condition of the eye than to compare medication names alone.

3. Do Eye Injections Hurt?

One of the most common concerns among patients receiving this recommendation for the first time is the idea of having medication injected directly into the eye.

During the actual procedure, the area around the eye is carefully disinfected to reduce the risk of infection, and topical anesthetic eye drops are applied before the medication is injected into the vitreous cavity.

Because the procedure is performed after topical anesthesia, most patients experience little significant pain, and the injection itself is usually completed within a short period of time.

The actual injection often takes only a few seconds, and many patients report that the procedure was less uncomfortable than they had expected.

Wet macular degeneration also often requires ongoing treatment rather than a single injection.

Tests such as optical coherence tomography, or OCT, are used to assess whether retinal swelling or bleeding has improved.

Based on these findings, the timing and interval of subsequent injections can be adjusted.

If severe eye pain, a sudden decrease in vision, marked redness, or other unusual symptoms occur after the procedure, it is important to visit an eye clinic promptly for evaluation.

4. The Introduction of Biosimilars Has Changed the Cost of Treatment

In the past, when certain injectable medications did not meet the criteria for National Health Insurance coverage, some patients faced out-of-pocket costs in the KRW 700,000 range.

As a result, some patients had difficulty choosing a medication that might be clinically appropriate because of the financial burden.

More recently, biosimilars have become available.

These medications are approved after demonstrating a high degree of similarity to existing biological medicines in terms of quality, efficacy, and safety.

As biosimilars have entered clinical use, the range of available treatment options has expanded.

Depending on the medication, insurance criteria, and pharmaceutical support programs, some patients may now receive treatment at a substantially lower cost, in some cases in the KRW 100,000 range.

However, the same price does not apply to every patient.

The actual out-of-pocket cost can vary depending on the medication used, insurance eligibility, the medical institution, and each patient's individual circumstances.

For this reason, it is most accurate to confirm the applicable cost at the time of consultation.

Even among patients with the same diagnosis of macular degeneration, the location and extent of the lesion, the activity of abnormal blood vessels, and the degree of bleeding or retinal swelling can vary considerably.

For this reason, it is difficult to determine your own treatment plan simply by comparing which medication another patient received or how frequently they were treated.

In wet macular degeneration, damage can accumulate in the part of the retina responsible for central vision.

Accurately assessing the current condition of the retina and beginning treatment at the appropriate time are therefore important.

In the past, the financial burden could be considerable when high-cost medications had to be used without insurance coverage.

Today, however, the introduction of biosimilars and other treatment options has provided patients with a wider range of choices, including options that may reduce treatment costs.

Even so, medication should not be selected based on price alone.

The condition of the retina, the response to previous treatment, and the applicable insurance criteria should all be considered when determining the most appropriate approach.

Many patients understandably feel anxious at first about having medication injected directly into the eye.

However, if intravitreal injection treatment is recommended for macular degeneration, it is important to review the examination findings carefully and receive a clear explanation of the medication being considered, the expected number of injections, and the potential cost.

Regular follow-up examinations also play an important role in long-term vision management, as the injection interval and choice of medication may need to be adjusted according to how the retina responds over time.

Thank you.

Ilsan Daehwa Station Eye Clinic: What Are the Features of the AMARIS RED System for 2-Day LASEK?

eyessg — Wed, 23 Sep 2026 14:22:12 +0900

Hello, this is Goyang Shinsegae Eye Clinic.

If you are considering vision correction surgery because of the inconvenience of wearing glasses or contact lenses, you may find yourself deciding between SMILE and 2-Day LASEK.

These procedures differ in how they are performed and in the technology they use, so it is important not to compare them based on a single feature alone. Instead, the overall condition of the eyes should be carefully evaluated.

In addition to visual acuity, factors such as corneal thickness and shape, the degree of myopia and astigmatism, and pupil size should be assessed before determining an appropriate vision correction plan for each patient.

Today, we will take a closer look at the differences between these two procedures, the key features of the AMARIS RED excimer laser system, residual corneal thickness, and the recovery process.

1. SMILE vs. 2-Day LASEK: What Are the Differences?

✔ Amount of Corneal Tissue Removed & Risk of Halos

2-Day LASEK can preserve more of the cornea's structural tissue after surgery, which may help reduce the risk of secondary complications such as corneal ectasia associated with excessive weakening of the cornea.

In comparison, SMILE may leave a thinner supporting stromal structure than surface ablation procedures such as LASEK, which may result in a relatively different biomechanical risk profile.

Corneal ectasia: A condition in which the cornea becomes structurally weakened and progressively protrudes after corneal refractive surgery such as LASIK or SMILE.

✔ Intraoperative Stability & Decentration

In both LASIK, including SMILE, and LASEK, accurate centration of the treatment zone—typically around 6 mm in the central cornea—is important.

However, even when a patient is asked to look steadily at a fixation target, small eye movements can occur during surgery because of tension or involuntary motion.

For this reason, many excimer laser systems are equipped with eye-tracking technology. The eye tracker continuously monitors eye movement and helps keep laser treatment aligned with the intended corneal treatment zone.

SMILE, however, does not use the same active eye-tracking system during lenticule creation. Instead, the eye is stabilized using a suction interface.

If the patient moves the eye significantly or if suction is lost during the procedure, a condition known as “suction loss” can occur.

Some reports have described suction loss occurring in a small percentage of SMILE procedures.

This is one of the intraoperative factors that may need to be considered when comparing different refractive surgery techniques.

With 2-Day LASEK, the treatment process is performed under laser guidance, whereas SMILE also involves manual separation and removal of the lenticule. This introduces a different set of procedure-specific risks, including irregular lenticule dissection or other stromal complications.

✅ Astigmatism Correction

2-Day LASEK may be considered for a wide range of refractive errors, including higher degrees of myopia and astigmatism.

With SMILE, the degree of astigmatism that can be treated may be limited depending on the platform, treatment parameters, and individual eye characteristics.

✅ Halos and Night Vision Symptoms

With 2-Day LASEK, the optical zone can be adjusted according to factors such as pupil size and treatment design.

In SMILE, there may be more limitations in modifying the optical zone, which can influence the possibility of postoperative halos or glare.

✅ Cost of Surgery

The cost of 2-Day LASEK may begin in the lower KRW 1 million range, whereas SMILE procedures may cost approximately KRW 2–4 million depending on the medical institution and surgical platform.

One reason SMILE may be more expensive is that it requires a single-use patient interface and other procedure-specific consumables.

The cost of these disposable components varies according to the equipment and platform used and may contribute to the overall surgical fee.

In comparison, 2-Day LASEK generally involves lower disposable equipment costs, which may result in a lower overall procedure fee.

2. What Are the Key Features of the AMARIS RED?

At our Daehwa Station eye clinic, the AMARIS RED system is used when performing 2-Day LASEK.

AMARIS RED is an excimer laser platform designed to deliver laser energy to selected areas of the cornea according to the patient's refractive error and the planned amount of correction.

One of its key features is a 7-dimensional eye-tracking system.

Even when a patient is looking at a fixed target, the eye can make subtle involuntary movements. The tracking system monitors these movements in real time and helps ensure that laser energy is delivered to the intended treatment area.

The system also incorporates real-time pachymetry, allowing corneal thickness changes to be monitored during the procedure and helping the surgeon assess the depth of laser ablation as treatment progresses.

3. Why Is Residual Corneal Thickness Important?

Because laser vision correction reshapes the cornea by removing a calculated amount of tissue, it is important to determine how much corneal tissue will remain after surgery.

Residual corneal thickness refers to the amount of corneal tissue remaining after the procedure.

This value can vary depending on the surgical technique, the patient's original corneal thickness, and the amount of refractive correction required.

Under the same comparison conditions, the residual corneal thickness has been described as approximately 227 μm after SMILE and 425 μm after 2-Day LASEK.

However, rather than comparing these figures alone, it is important to undergo a comprehensive preoperative examination to assess the current corneal structure and estimate the expected residual thickness before selecting a surgical method.

4. An All-Laser Approach

In conventional LASEK, alcohol or a surgical brush may be used during epithelial removal, which can cause chemical or mechanical stimulation of the corneal surface.

In contrast, all-laser LASEK using the AMARIS RED can use laser energy from epithelial removal through refractive correction, helping reduce unnecessary physical contact with the cornea.

Another feature of the system is its small 0.54 mm laser spot size, which is designed to allow precise delivery of laser energy to the targeted area.

For patients considering a surface ablation procedure using a highly precise laser platform, these are some of the technical features of the AMARIS RED that may be worth reviewing.

SMILE and 2-Day LASEK differ in both their surgical techniques and clinical characteristics.

A laser platform such as the AMARIS RED also offers various functions that can support the vision correction process, but the choice of procedure should not be based on the equipment alone.

Even among patients considering LASEK, individual factors such as the degree of myopia or astigmatism, pupil size, corneal thickness, corneal shape, and the presence of dry eye can vary considerably.

For this reason, it is more important to first understand the condition of your own eyes through a comprehensive examination rather than focusing only on the advantages, disadvantages, or cost of a particular procedure.

If you are considering vision correction surgery in the Ilsan area, a detailed eye examination and consultation with an ophthalmologist can help determine which procedures may be suitable for you and what type of recovery process you can expect.

Thank you.

Causes of Watery Eyes at a Goyang Eye Clinic: Persistent Tearing, Symptoms, and Treatment Options

eyessg — Tue, 22 Sep 2026 17:34:03 +0900

Hello, this is Goyang Shinsegae Eye Clinic.

Some people notice that their eyes water easily when exposed to cold winter winds or when spending long periods of time in a dry environment.

If this happens only temporarily, environmental factors may be the cause. However, if tears flow frequently or continuously pool in the eyes, it may be necessary to check for other underlying problems.

The causes of excessive tearing can generally be divided into two categories.

One is an increase in tear production, and the other is a problem in which tears cannot drain properly through their normal pathway.

Therefore, rather than judging the condition based on symptoms alone, it is important to determine which part of the tear production or drainage process is causing the problem.

Contents

1) How Tears Are Normally Produced and Drained
2) Why Excessive Tear Production Occurs
3) Blocked Tear Drainage Can Also Cause Persistent Tearing
4) Treatment Options Depend on the Location of the Blockage
5) When Is Lacrimal Endoscopy Used?
6) If Tearing Keeps Recurring, Identifying the Cause Comes First

✅️ 1. How Tears Are Normally Produced and Drained

To understand the causes of excessive tearing, it is helpful to first understand how tears are normally produced and drained.

Tears produced by the lacrimal gland spread across the surface of the eye to keep it moist and then pass through the puncta, small openings located near the inner corners of the eyelids.

From there, they travel through the canaliculi and lacrimal sac before draining toward the nose.

To put it simply, if the lacrimal gland acts like a “water supply system,” the drainage pathway leading toward the nose functions like a “sewer system.”

Therefore, when persistent tearing occurs, two possibilities should be considered.

◼ Whether an excessive amount of tears is being produced
◼ Whether the normal drainage pathway has become narrowed or blocked

Having watery eyes does not necessarily mean that too many tears are being produced.

If the drainage pathway is blocked, tears may overflow onto the cheeks even when tear production itself is normal.

✅️ 2. Why Excessive Tear Production Occurs

The first possible cause is an actual increase in tear production. One common example is reflex tearing.

When eyelashes rub against the eye, a foreign body enters the eye, or inflammation or injury occurs, tear production may increase as a protective response.

Dry eye syndrome can also be a cause.

When the ocular surface becomes dry, irritation may occur, and the eyes may respond by producing an increased amount of tears as a protective mechanism.

Therefore, watery eyes should not automatically be interpreted as evidence that dry eye syndrome is absent.

Other possible causes include inflammation of the lacrimal gland, certain medications, or facial nerve palsy. If the eyelids do not close properly due to facial nerve dysfunction, ongoing exposure and irritation of the ocular surface may lead to excessive tearing.

In rare cases, abnormal nerve regeneration after facial nerve palsy may cause tearing while eating or even when looking at food. This phenomenon is sometimes referred to as “crocodile tears.”

✅️ 3. Blocked Tear Drainage Can Also Cause Persistent Tearing

Another major cause of excessive tearing is narrowing or blockage of the drainage pathway leading toward the nose.

Near the inner corner of each eyelid is a small opening called the punctum, through which tears normally drain.

If this opening becomes narrowed, tears cannot drain efficiently and may accumulate on the surface of the eye before overflowing.

After passing through the punctum, tears normally travel through the canaliculi and lacrimal sac before reaching the nasal cavity.

Problem Area	What to Check
Punctum	Narrowing or blockage of the drainage opening
Canaliculus	Narrowing or obstruction of the drainage channel
Lacrimal sac / nasolacrimal duct	Problems affecting drainage toward the nose
Lower eyelid	Reduced drainage function due to eyelid laxity
Conjunctiva	Interference with tear movement caused by loose or redundant tissue

If severe eyelid inflammation has occurred in the past or glaucoma eye drops have been used for a long period of time, the punctum may become narrowed.

Even when there is no complete blockage, excessive laxity of the lower eyelid or redundant conjunctival tissue may interfere with the normal movement of tears toward the drainage opening.

Therefore, treatment methods may differ depending on the exact location of the problem.

✅️ 4. Treatment Options Depend on the Location of the Blockage

If an examination at a Goyang eye clinic confirms obstruction of the tear drainage pathway, treatment is selected according to the location and severity of the blockage.

If the punctum is narrowed or blocked, punctoplasty may be considered.

This procedure widens the drainage opening so that tears can pass through more effectively.

If narrowing is found in the canaliculus, lacrimal sac, or nasolacrimal duct, silicone tube intubation may be considered in selected cases.

With conventional techniques, instruments are inserted through the drainage pathway, and the physician may rely partly on tactile feedback while passing through the narrowed area.

When the narrowing is severe, passage may be difficult, and there is also a possibility that the instrument may deviate from the normal pathway and create a false passage.

If obstruction around the lacrimal sac is severe or cannot be adequately addressed with other methods, endoscopic dacryocystorhinostomy may be considered. This procedure creates a new drainage pathway between the lacrimal sac and the nasal cavity using an endoscope inserted through the nose.

In other words, the same procedure is not applied to every patient.

The location and degree of obstruction should first be identified before choosing an appropriate treatment method.

✅️ 5. When Is Lacrimal Endoscopy Used at a Goyang Eye Clinic?

Lacrimal endoscopy is one method used to directly examine the inside of the tear drainage pathway.

A very small camera, approximately 0.9 mm in diameter, is inserted through the punctum to examine the internal condition of the canaliculi and lacrimal sac.

In conventional procedures, there may be some reliance on the physician’s tactile sensation when advancing an instrument through the drainage pathway.

Lacrimal endoscopy differs in that it allows the physician to directly visualize the inside of the drainage system while identifying the location and condition of any obstruction.

If inflammatory material, stones, or fibrous adhesions are found inside the pathway, the endoscopic tip may also be used to assist with their removal in appropriate cases.

Internal examination → Identification of the blocked area → Assessment of the condition → Appropriate treatment

Frequently Asked Questions

Q. If my eyes keep watering, does that mean I do not have dry eye syndrome?

A. No. Dry eye syndrome can irritate the ocular surface and trigger reflex tear production as a protective response. Therefore, excessive tearing alone cannot determine whether dry eye syndrome is present.

Q. If the tear drainage pathway is blocked, is surgery always necessary?

A. Not necessarily. The appropriate treatment depends on the location and severity of the blockage. A narrowed punctum should be distinguished from obstruction involving the canaliculi or lacrimal sac, and treatment should be selected according to the individual condition.

Q. If my symptoms become worse in winter, is the weather the only reason?

A. Cold wind and dry air can irritate the ocular surface and make tearing more noticeable. However, if tears continuously pool in the eyes or overflow onto the cheeks, dry eye syndrome or abnormalities of the tear drainage pathway should also be evaluated.

✅️ 6. If Tearing Keeps Recurring, Identifying the Cause Comes First

There is no single cause of excessive tearing.

Tear production may increase because of dry eye syndrome or irritation of the ocular surface, while in other cases, the drainage pathway leading toward the nose may become narrowed or blocked, causing tears to overflow.

In particular, if tearing occurs frequently throughout the day and you need to wipe your eyes repeatedly, it should not automatically be attributed to the weather alone.

The first step is to determine whether too many tears are being produced or whether the tears are not draining properly.

Depending on the findings of an examination at a Goyang eye clinic, treatment may involve management of the ocular surface, punctoplasty, silicone tube intubation, lacrimal endoscopy, or dacryocystorhinostomy.

Ultimately, when excessive tearing continues to recur, the key is to identify where the problem is occurring and select a treatment method based on the underlying cause.

Thank you.

Ilsan Jichuk Station Eye Clinic: Understanding Injections for Macular Degeneration, Medications, and Costs

eyessg — Mon, 21 Sep 2026 18:28:29 +0900

Hello. This is Goyang Shinsegae Eye Clinic, serving the Ilsan area.

When patients first hear about injection treatment for macular degeneration, the idea of having medication injected directly into the eye can understandably feel intimidating.

Hearing that repeated injections may be necessary can also raise concerns about the cost of treatment.

Wet age-related macular degeneration is a condition that requires active management.

This is because abnormal new blood vessels can develop beneath or within the retina, and bleeding or fluid leakage from these vessels may directly affect central vision.

One of the main treatments used to suppress the activity of these abnormal blood vessels is the injection of medication into the eye.

In recent years, a wider range of medications has become available, which has also led to changes in the financial burden associated with treatment.

If you are looking for an eye clinic near Jichuk Station, it is important to understand why these injections are needed and how the appropriate medication is selected, rather than comparing cost alone.

Contents

Why are injections necessary for wet macular degeneration?
Concerned about injections into the eye? What does the procedure actually involve?
Why are different medications used?
Treatment costs have also changed in recent years
Q&A about injection treatment for macular degeneration
What should be considered before cost?

✅️ 1. Why Are Injections Necessary for Wet Macular Degeneration?

The macula is located at the center of the retina and plays a critical role in clear, detailed vision.

Macular degeneration is generally classified into two types: dry and wet.

In wet macular degeneration, abnormal new blood vessels develop, and blood or fluid may leak from these vessels, potentially damaging retinal tissue.

Injection treatment for macular degeneration commonly uses medications that inhibit vascular endothelial growth factor, or VEGF, which plays an important role in the formation of abnormal blood vessels.

To put it simply:

◼ Abnormal new blood vessels develop.
◼ Blood or fluid may leak from these vessels.
◼ Bleeding or swelling may occur in the central retina.
◼ Depending on the examination results, medication may be injected into the eye.

Therefore, when undergoing an examination at an eye clinic near Jichuk Station, one of the first things to assess is whether abnormal blood vessels, bleeding, or retinal swelling are present.

The key issue is not simply the fact that medication is injected into the eye.

What matters most is accurately determining how active the abnormal blood vessels are and what changes have occurred in the retina.

✅️ 2. Concerned About an Injection Into the Eye? What Does the Procedure Actually Involve?

Even after understanding why treatment may be necessary, many patients are understandably concerned about having medication injected directly into the eye.

An intravitreal injection is performed after appropriate anesthesia and disinfection of the eye.

The actual injection itself usually takes only a short amount of time.

It is important not to delay necessary treatment solely because of fear of the procedure.

Whether injection treatment for macular degeneration is needed is determined not simply by symptoms, but by objective examination findings such as fundus examination and optical coherence tomography, or OCT.

Therefore, when looking for an eye clinic near Jichuk Station, it is better to first determine the current condition of the retina rather than worrying immediately about whether an eye injection will be necessary.

✅️ 3. Why Are Different Medications Used?

There is more than one medication that can be used for injections into the eye.

Common examples include Avastin (bevacizumab), Lucentis (ranibizumab), and Eylea (aflibercept).

Category	What to Consider
Type	Active ingredient and characteristics of the medication
Insurance	Eligibility criteria for National Health Insurance coverage
Retinal condition	Presence of abnormal blood vessels, bleeding, or swelling
Response	How the eye responded to previous injections
Treatment plan	Whether additional injections are needed and the interval between treatments

Each medication has different characteristics, approved indications, and insurance coverage criteria.

The condition of the retinal lesion and the patient's response to previous injections are also considered when selecting the medication.

For this reason, a more expensive medication should not automatically be considered the better option.

The severity of the condition, previous treatment response, required injection interval, and insurance coverage should all be considered together.

When receiving care at an eye clinic near Jichuk Station, the most important factor is finding an option that is appropriate for the current condition of the eye rather than focusing only on price or brand recognition.

✅️ 4. Treatment Costs Have Also Changed in Recent Years

For patients who require repeated treatment, cost is understandably an important practical concern.

In the past, when certain injectable medications did not meet the criteria for National Health Insurance coverage, out-of-pocket costs could reach the KRW 700,000 range.

More recently, the introduction of biosimilars has expanded the available options, and depending on the circumstances, treatment may be available in the KRW 100,000 range.

A biosimilar is a biological medication that has been shown to be highly similar to an already approved reference biologic in terms of quality, efficacy, and safety.

✅️ 5. Q&A About Injection Treatment for Macular Degeneration

Q. Is a more expensive medication necessarily better?

A. No. Price alone cannot determine which medication is most appropriate.

Each medication has different characteristics and insurance coverage criteria, and each patient's retinal condition and response to previous treatment may also differ.

The important point is to select a medication that is appropriate for the current condition of the eye.

✅️ 6. What Should Be Considered Before Cost?

Wet macular degeneration should not be viewed as a condition that is completely treated after a single procedure.

The condition of the retina and the activity of the disease need to be monitored over time, and the need for additional treatment and the appropriate interval between injections must be determined accordingly.

For this reason, the first question to ask about injection treatment for macular degeneration should not be, “How much does the medication cost?”

It is more important to determine whether abnormal new blood vessels are present, whether bleeding or swelling has occurred, how far the condition has progressed, and which treatment approach is appropriate.

If you are looking for retinal care at an eye clinic near Jichuk Station, it is important not to miss an appropriate treatment window because of fear of eye injections or concerns about cost.

Compared with the past, treatment options have expanded, including the availability of biosimilars.

Because there may now be options that can reduce the financial burden in certain cases, treatment decisions should be based on examination findings, the current condition of the eye, insurance eligibility, and the planned course of follow-up care.

Thank you.

Haengsin-dong Eye Clinic: Comparison of Eyhance, Vivity, and PureSee Lenses and Postoperative Precautions

eyessg — Mon, 21 Sep 2026 17:46:39 +0900

Hello,

This is Goyang Shinsegae Eye Clinic.

As people age, many begin to notice that

small letters in books or on smartphones

are no longer as clear as they once were,

or that it takes longer for their eyes

to refocus when shifting their gaze

from a nearby object to something farther away.

These changes are associated with presbyopia,

which occurs as the natural lens of the eye

gradually loses its ability to adjust focus with age.

If cataracts develop at the same time,

vision may become generally cloudy or hazy,

and symptoms such as glare,

halos around lights, and changes in color perception

may also occur.

Today, when planning cataract surgery,

the goal is often not limited to simply

removing the cloudy natural lens.

Many patients also consider

how comfortably they would like to see

at different distances after surgery.

As more people seek to reduce their dependence on glasses

and achieve more comfortable vision

at both far and intermediate distances,

interest has grown in intraocular lenses

such as Vivity, PureSee, and Eyhance.

1. Why Is an Intraocular Lens Needed in Cataract Surgery?

The natural lens inside the eye

functions much like the lens of a camera.

It refracts incoming light

so that it can focus on the retina,

allowing us to see objects clearly.

However, as we age,

changes can occur in the proteins

and other components of the natural lens.

As a result, the lens may gradually lose its transparency

and become cloudy.

This condition is known as a cataract.

If a cataract progresses to the point

that reduced vision interferes with daily activities,

surgery may be considered

after an appropriate examination and consultation.

Cataract surgery involves removing the cloudy natural lens

and replacing it

with an artificial intraocular lens.

Because the range of focus

and visual characteristics after surgery

can vary depending on the type of intraocular lens selected,

it is important to consider

your lifestyle and visual needs carefully.

2. EDOF Lenses

EDOF stands for “Extended Depth of Focus.”

These lenses are designed

to extend the range over which vision remains clear,

allowing patients to see not only at a distance

but also at intermediate ranges.

Intermediate vision is frequently required

in modern daily life,

such as when checking a navigation screen

or dashboard while driving,

or when looking at a desktop computer monitor.

For this reason,

many patients are interested in EDOF lenses.

3. Main Advantages

① Natural Vision from Far to Intermediate Distances

EDOF lenses are designed

to provide a continuous range of focus,

helping patients see more naturally

across far and intermediate distances.

This can be helpful in many everyday situations,

such as checking the dashboard while driving,

working on a computer,

shopping, cooking, or performing household tasks.

② Potentially Reduced Glare and Halos

EDOF lenses are designed

with the aim of reducing optical disturbances

such as glare, halos, and light scatter.

For patients who frequently drive at night

or who place a high priority

on visual quality in dim environments,

they may be one of the options worth considering.

③ Relatively Good Quality of Vision

These lenses are optically designed

to minimize unnecessary light loss

and may help preserve contrast sensitivity

to a relatively good degree.

④ Smooth Transition Between Focal Distances

Another characteristic

is that the transition in focus

when looking from near to far distances

can feel relatively natural.

This may provide more comfortable vision

in everyday situations

where patients frequently shift their gaze

between objects at different distances.

4. Comparison of Common EDOF and Enhanced Monofocal Lenses

1) Vivity

Vivity is a non-diffractive EDOF intraocular lens

developed by Alcon.

It is designed to provide clear distance vision

while extending the range of focus

toward intermediate distances

in a relatively natural manner.

2) PureSee

PureSee is an EDOF intraocular lens

developed by Johnson & Johnson Vision.

It is designed to continuously extend

the range of focus

from distance to intermediate vision,

providing a smooth and natural visual transition.

3) Eyhance

Unlike Vivity and PureSee,

Eyhance is classified

as an enhanced monofocal intraocular lens.

It is designed to preserve the advantages

of a conventional monofocal lens

while providing some improvement

in intermediate vision.

It may be considered by patients

who place particular importance on distance vision

but would also like

a somewhat broader range of vision

than that provided by a conventional monofocal lens.

5. Precautions After Cataract Surgery

When washing your face or taking a shower

after cataract surgery,

care should be taken

to prevent water from entering the eye directly.

The appropriate time to resume

normal face washing or showering

may vary depending on the patient's recovery,

so it is important to follow

the instructions provided by the medical institution

where the surgery was performed.

Prescribed eye drops should also be used

regularly according to the recommended dosage and schedule.

Patients should not reduce the frequency

or discontinue the medication on their own.

It is also advisable to avoid

rubbing the operated eye

or engaging in activities

that may place excessive pressure on the eye.

If necessary,

an eye shield may be worn

for a certain period of time

according to the medical team's instructions

to help protect the operated eye.

Regular follow-up examinations

should also be attended as scheduled

to monitor visual recovery,

check the healing process,

and ensure that no unusual problems have developed.

Gimpo Eye Clinic: What If Dry Eye Discomfort Continues Despite Using Artificial Tears?

eyessg — Fri, 18 Sep 2026 17:54:15 +0900

Hello, this is Goyang Shinsegae Eye Clinic.

Some people experience persistent discomfort such as dryness, stinging, or a gritty sensation that feels as though sand is trapped in the eyes.

When these symptoms occur, many people first reach for artificial tears.

However, dry eye syndrome does not occur simply because the eyes lack moisture.

A variety of factors may contribute to the condition, including lifestyle habits, environmental conditions, and certain medications.

In particular, recurring dryness may also be associated with dysfunction of the meibomian glands located in the eyelids.

Therefore, if discomfort continues despite using artificial tears, it is important to determine what may be causing the symptoms.

Tears Are Made Up of More Than Just Water

Tears help keep the surface of the eye moist and protect it from external irritation.

The tear film consists of several components, including a protein layer, an aqueous layer, and an oil layer, each of which performs a different function.

If certain protein components are insufficient, eye drops that promote tear secretion may be considered. If the aqueous component is lacking, artificial tears containing ingredients such as hyaluronic acid may be used to supplement moisture.

However, if the oil layer is not functioning properly, a different approach may be necessary.

This is because the oil component helps prevent moisture from evaporating too quickly from the surface of the eye.

Why Is Meibomian Gland Function Important?

The meibomian glands are located within the eyelids and release an oily substance each time you blink.

When this oil is secreted normally, it spreads across the surface of the eye and helps prevent tears from evaporating too quickly.

However, if debris accumulates around the openings of the glands or inflammation develops, the oil may not flow properly.

In this situation, artificial tears may provide temporary relief, but dryness and irritation can return shortly afterward.

Therefore, when dryness persists, it is important to consider not only a lack of moisture but also the condition and function of the meibomian glands.

How Does LipiFlow Work for Dry Eye Syndrome?

LipiFlow is a treatment that uses controlled heat and pressure to help manage the glands located in the eyelids.

A specially designed device is placed over the eye and eyelids, similar to wearing a contact lens, and delivers controlled heat at approximately 40°C.

The heat helps soften hardened or thickened gland secretions. Gentle pressure is then applied to the inner and outer surfaces of the eyelids to help express accumulated material from the glands.

Step Description

Step 1 Placement of the specialized device

Step 2 Delivery of controlled heat at approximately 40°C

Step 3 Softening of hardened gland secretions

Step 4 Application of pressure to the inner and outer eyelids

Step 5 Assistance with the expression of accumulated secretions

In other words, LipiFlow for dry eye syndrome works differently from simply adding moisture to the surface of the eye.

It is designed to focus on the function of the meibomian glands, which are closely related to the formation and stability of the tear film's oil layer.

Artificial Tears vs. LipiFlow: What Is the Difference?

The two approaches serve different purposes.

Artificial tears are generally used to supplement moisture on the surface of the eye.

However, if the function responsible for forming the oil layer is impaired, the added moisture may evaporate quickly, causing dryness to return.

Therefore, if you frequently use artificial tears but continue to experience dryness, grittiness, or irritation, it may be more helpful to identify the underlying cause rather than simply increasing how often you use eye drops.

In particular, if the openings of the meibomian glands are blocked or oil secretion is reduced, the condition of the glands should be evaluated before determining an appropriate management plan.

Q&A | Common Questions About LipiFlow for Dry Eye Syndrome

Q. Why do my eyes still feel dry even when I use artificial tears?

A. In addition to insufficient moisture, the problem may be related to inadequate formation of the tear film's oil layer.

If there is not enough oil on the surface of the eye, moisture may evaporate more quickly, causing dryness to return.

Q. Does everyone with dry eye syndrome need LipiFlow?

A. No. Dry eye syndrome can have many different causes, so the same treatment is not appropriate for every patient.

It is important to first determine whether the problem is primarily related to insufficient moisture, abnormal oil secretion, or another contributing factor before considering the most appropriate treatment or management method.

Dry eye syndrome cannot be explained simply as a condition caused by insufficient moisture.

Several factors may contribute, including the composition of the tear film, oil secretion from the eyelids, lifestyle habits, environmental conditions, and medications currently being taken.

In particular, if the meibomian glands are not functioning properly, the oil layer may not form adequately, allowing moisture on the surface of the eye to evaporate more easily.

LipiFlow is a treatment that uses controlled heat and pressure to help soften and express hardened secretions from the meibomian glands in these cases.

Therefore, if dryness continues despite using artificial tears, it is important not to rely repeatedly on only one approach. Instead, the cause should be evaluated to determine whether the problem involves insufficient moisture, an unstable oil layer, or impaired gland function in the eyelids.

Why You Should Get Screened for the Three Major Causes of Blindness Even When You Have No Symptoms

eyessg — Thu, 17 Sep 2026 13:51:51 +0900

Hello, this is Goyang Shinsegae Eye Clinic, an ophthalmology clinic serving the Ilsan area.

“Do I really need regular eye examinations even if I can still see well?”

Many people assume that they only need to visit an ophthalmologist when their vision becomes blurry or when they begin to experience noticeable discomfort.

However, eye diseases do not always begin with obvious symptoms.

Diabetic retinopathy, age-related macular degeneration, and glaucoma are considered three major eye diseases that can lead to severe vision loss or blindness.

Although their causes and the parts of the eye they affect are different, they share one important characteristic: in the early stages, there may be few or no symptoms that a person can notice on their own.

For this reason, it is important not to assume that your eyes are healthy simply because your current vision seems normal. Regular eye examinations at an ophthalmology clinic near Jichuk can help assess the retina, optic nerve, and other internal structures of the eye.

1. How Are the Three Major Causes of Blindness Different?

To understand these three conditions, it is helpful to first distinguish which part of the eye is primarily affected.

Condition	Main Characteristics	Possible Symptoms as the Disease Progresses
Diabetic retinopathy	Damage to small retinal blood vessels caused by diabetes	Decreased vision, floaters, distortion of central vision
Age-related macular degeneration	Degenerative changes affecting the macula	Blurred central vision, straight lines appearing wavy
Glaucoma	Progressive damage to the optic nerve	Gradual narrowing of the visual field

Because these conditions affect different structures of the eye, they cannot all be evaluated with a single test. Depending on the patient's condition, examinations may include a fundus examination, optical coherence tomography (OCT), intraocular pressure measurement, and visual field testing.

So, what are the main characteristics of each condition?

normal retina

diabetic retinopathy

OCT image of diabetic retinopathy with macular edema

normal retinal OCT image

2. If You Have Diabetes, Regular Eye Examinations Are Important

Diabetic retinopathy occurs when prolonged high blood sugar levels damage the small blood vessels in the retina.

In the early stages, there may be little or no noticeable discomfort. However, as the condition progresses, bleeding or retinal swelling may develop.

In more advanced cases, abnormal new blood vessels may form, potentially leading to vitreous hemorrhage or retinal detachment.

Symptoms may include reduced vision, floaters that look like spots or threads moving in front of the eyes, or distortion of central vision.

Therefore, if you have been diagnosed with diabetes, it is important to have your eyes checked regularly, even if your current vision seems normal. A fundus examination and OCT may be used to assess the retina.

The appropriate examination interval may vary depending on each individual's condition.

3. What If Straight Lines Look Wavy or the Center of Your Vision Appears Blurred?

The second condition is age-related macular degeneration.

The macula is located at the center of the retina and is responsible for detailed central vision, such as reading letters and recognizing faces.

Age-related macular degeneration occurs when degenerative changes develop in this area.

The dry form generally progresses more slowly, whereas the wet form can cause more rapid vision loss due to the growth of abnormal new blood vessels.

If straight lines that once appeared normal begin to look wavy, or if the center of your vision appears blurred, distorted, or partially blocked, it is important not to assume that these changes are simply part of normal aging.

If these symptoms occur, an eye examination can help determine the underlying cause.

normal visual field

visual field of a patient with advanced glaucom

4. Why Is Glaucoma Difficult to Detect Early?

Glaucoma is an eye disease in which progressive damage to the optic nerve causes the visual field to gradually narrow.

Because it can be difficult to notice in its early stages, glaucoma is sometimes referred to as a “silent thief of sight.”

When peripheral vision deteriorates slowly, a person may not immediately notice any changes during everyday activities.

normal optic nerve

optic nerve affected by glaucoma

In addition, some people develop normal-tension glaucoma, in which optic nerve damage occurs even though intraocular pressure remains within the statistically normal range.

For this reason, a normal eye pressure reading alone does not necessarily rule out glaucoma.

Damage to the optic nerve is generally irreversible. Therefore, early detection and appropriate management of intraocular pressure are important for slowing further visual field loss.

Evaluation may include not only intraocular pressure measurement but also examination of the optic nerve and visual field.

Q&A | Common Questions About the Three Major Causes of Blindness

Q. Do I need an eye examination even if I do not have any symptoms?

A. Diabetic retinopathy, age-related macular degeneration, and glaucoma may cause few or no noticeable symptoms in their early stages. In some cases, the disease may already have progressed significantly by the time symptoms become apparent. If you have risk factors, regular eye examinations are important for monitoring your eye health.

Q. Who should be especially cautious?

A. Regular eye examinations may be particularly important for people over the age of 40, those with diabetes or high blood pressure, people with high myopia, and those with a family history of glaucoma or age-related macular degeneration. Smoking history and increasing age may also be associated with a higher risk of certain eye diseases.

Q. What tests may be performed during an eye examination near Jichuk Station?

A. Depending on the patient's condition and individual risk factors, examinations may include a fundus examination, OCT, intraocular pressure measurement, and visual field testing. Not every person requires the same set of tests, and the appropriate examination methods may vary depending on the condition being evaluated.

The most important point to remember about these three major causes of blindness is that relying only on the rule of “I will visit an ophthalmologist when my eyes become uncomfortable” may make early detection difficult.

Diabetic retinopathy and age-related macular degeneration can affect the retina, while glaucoma is associated with progressive damage to the optic nerve.

Because vision loss or structural damage that has already occurred may be difficult or impossible to reverse, detecting abnormalities as early as possible and beginning appropriate management is important.

For this reason, developing the habit of having regular eye examinations at an ophthalmology clinic near Jichuk is recommended.

In particular, people with risk factors such as diabetes, high blood pressure, high myopia, or a family history of eye disease should not delay examinations simply because they currently have no noticeable discomfort.

If you are looking for information about ophthalmology clinics near Jichuk Station or in the Ilsan area, it may be helpful to consider not only basic visual acuity testing but also how the retina, optic nerve, and other internal structures of the eye can be evaluated.

The purpose of regular eye examinations is not simply to identify a problem after symptoms become severe, but to detect changes that may be difficult to notice on your own as early as possible.

Thank you.

Presbyopia Surgery Methods and Precautions at an Eye Clinic Near Juyeop Station, Ilsan Seo-gu

eyessg — Wed, 16 Sep 2026 17:13:51 +0900

Hello,
this is Goyang Shinsegae Eye Clinic.

Around the mid-40s, many people begin to notice that text messages on their smartphones or small print in books are no longer as clear as they used to be.

At first, it may be easy to dismiss these changes as simple eye fatigue.

However, if you need to hold your smartphone farther away than usual to read comfortably, or if it takes longer for your eyes to refocus when looking from a nearby object to something in the distance, presbyopia may be a possible cause.

Recently, more people have been exploring not only reading glasses or corrective eyewear but also surgical options to reduce the inconvenience caused by presbyopia.

However, the appropriate type of presbyopia surgery may vary depending on the current condition of the eyes and whether cataracts are also present.

For this reason, it is important to make a decision based on a thorough eye examination.

1. Why Does Presbyopia Occur?

Presbyopia is an age-related condition in which the eye gradually loses its ability to focus clearly on nearby objects.

The natural lens inside the eye helps adjust the eye’s focusing power when looking at objects at different distances.

When we are younger, the lens is relatively flexible and the focusing mechanism of the eye works efficiently.

As a result, the eyes can quickly adjust when shifting focus between near and distant objects.

However, as we age, the natural lens gradually becomes less flexible, and the eye’s focusing ability begins to decline.

This can make it more difficult to focus on nearby objects, causing small print to appear blurry or leading people to hold books and smartphones farther away in order to see more clearly.

2. Common Symptoms of Presbyopia

One of the first changes people often notice with presbyopia is difficulty with near vision.

Small letters at close range may no longer appear clear, and reading a smartphone or book may feel more comfortable when it is held farther away than before.

Some people may also notice that their eyes take longer to adjust when shifting their gaze between near and distant objects.

After prolonged reading or extended use of a computer or smartphone, the eyes may become tired more easily.

In some cases, eye strain, a heavy sensation around the eyes, or headaches may also occur.

3. Presbyopia vs. Cataracts: What Is the Difference?

1) Presbyopia

Presbyopia is an age-related decline in the eye’s focusing ability.

The main symptom is difficulty seeing small print or nearby objects clearly.

2) Cataracts

A cataract is a condition in which the normally clear natural lens of the eye becomes cloudy.

Depending on the location and severity of the lens opacity, symptoms may include blurred or hazy vision, glare, halos around lights, and reduced contrast sensitivity.

In some cases, vision may remain unclear even after changing the prescription for glasses.

Therefore, if you are experiencing not only difficulty reading nearby text but also persistent blurred vision, glare, or an overall decline in visual clarity, it is important not to assume that presbyopia is the only cause.

An ophthalmologic examination can help determine whether cataracts are also present.

4. How Is the Appropriate Presbyopia Surgery Determined?

When cataracts are present, one surgical option for addressing presbyopia involves removing the cloudy natural lens and replacing it with an artificial intraocular lens.

A conventional monofocal intraocular lens is designed to provide focus at a specific distance.

For example, if the lens power is selected to optimize distance vision, reading glasses or near-vision glasses may still be required for tasks such as reading small print after surgery.

In contrast, multifocal or extended depth of focus (EDOF) intraocular lenses are designed to use specific optical properties to reduce dependence on glasses across multiple viewing distances, such as far, intermediate, or near vision.

However, the same type of presbyopia surgery is not suitable for everyone.

Before surgery, it is important to evaluate the condition of the cornea, retina, macula, and optic nerve, as well as the degree of astigmatism and the presence of any existing eye disease.

Lifestyle factors are also important when selecting an intraocular lens.

For example, the choice may be influenced by whether a patient spends a significant amount of time using a computer, frequently reads or uses a smartphone, or often drives at night.

5. Presbyopia Surgery Method and Procedure

When cataract surgery is performed, it is generally carried out under topical anesthesia using anesthetic eye drops.

A small incision is made in the cornea, typically measuring approximately 2 to 2.8 mm, to access the lens capsule.

Using a technique called phacoemulsification, the cloudy contents of the natural lens are broken into small pieces with ultrasound energy and removed from the eye.

An artificial intraocular lens with a power calculated according to the patient’s individual eye measurements is then inserted into the position where the natural lens was located.

6. Precautions After Presbyopia Surgery

During the recovery period, patients should avoid rubbing their eyes or applying strong pressure to them.

Immediately after surgery, particular care should be taken to prevent impact or unnecessary irritation to the eye.

Strenuous exercise, swimming, and sauna use may increase irritation or the risk of infection, so these activities should generally be avoided for the period recommended by the medical team.

The appropriate time to resume daily activities such as washing the face, showering, and exercising may vary depending on each patient’s recovery.

Therefore, it is important to follow the postoperative instructions provided by your ophthalmologist.

Regular follow-up examinations are also important even if no particular discomfort is present after surgery.

If you experience a sudden decrease in vision, severe eye pain, significant redness, or any other unusual symptoms, it is advisable to contact an ophthalmology clinic promptly rather than waiting until the next scheduled appointment.

Early Signs of Myopia in Children and Atropine Treatment: A Must-Read Guide

eyessg — Wed, 16 Sep 2026 16:32:04 +0900

Hello,

This is Goyang Shinsegae Eye Clinic.

When a child's vision begins to deteriorate, many parents immediately think of glasses.

“Wouldn't it be enough to simply prescribe the right glasses?”

“Will atropine eye drops improve my child's myopia?”

These are some of the questions we frequently receive.

For children with myopia, glasses correct blurred vision and help them see clearly, but they are different from treatments designed to slow the progression of myopia.

In particular, because children's eyes can continue to grow along with their bodies during the developmental years, it is important to monitor not only their current vision but also how quickly their myopia is progressing.

Recently, low-dose atropine eye drops have been considered as one of the methods for managing myopia progression in children.

1. Why Does Myopia in Children Continue to Progress?

Myopia is a refractive error in which light entering the eye is focused in front of the retina rather than directly on the retina.

Although several factors can contribute to myopia, it is closely associated with an increase in the length of the eye from front to back, known as the axial length.

During childhood, the eyes grow just as the rest of the body grows.

If the axial length becomes excessively long, the degree of myopia may increase. As a result, even after a child receives a new pair of glasses, distant objects may become blurry again after some time.

Children's myopia can be influenced by a variety of factors, including genetic factors such as parental myopia, prolonged reading and studying, increased near-work activities such as using smartphones and tablets, insufficient outdoor activity, and environmental factors.

Therefore, rather than simply checking the child's current visual acuity, it is helpful to regularly monitor both refractive status and changes in axial length.

2. What Are the Early Signs of Myopia?

One of the most common early signs of myopia in children is reduced distance vision, in which objects that are far away appear blurrier than before.

However, young children may not be able to recognize or accurately explain that their vision has deteriorated, which makes it important for parents and caregivers to observe their behavior.

A child may say that they cannot see the writing on the classroom board clearly or may start sitting unusually close to the television.

Other signs to look out for include squinting or frequently narrowing the eyes when looking at distant objects, as well as bringing objects closer to the face in order to see them.

Children may also frequently complain of eye strain or experience headaches and difficulty concentrating while studying.

If these behaviors occur repeatedly, it is recommended not to assume that they are simply habits. Instead, the child should undergo a comprehensive eye examination, including visual acuity and refractive testing, at an eye clinic.

3. What Is Atropine Treatment for Childhood Myopia?

Atropine eye drops are a form of medical treatment that may help slow the progression of myopia in growing children.

They are generally administered once a day, with one drop placed in each eye before bedtime, according to the treatment plan prescribed by the ophthalmologist.

4. Why Consider Atropine Treatment?

1) To help control excessive axial elongation

Childhood myopia often progresses as the axial length of the eye continues to increase during growth.

Children who develop myopia at a young age or whose prescription increases rapidly require particularly careful monitoring.

2) To reduce the risk of progression to high myopia

When myopia continues to progress and becomes high myopia, the risk of certain eye conditions later in adulthood may increase, including retinal detachment, myopic maculopathy, and glaucoma.

For this reason, it is important to regularly monitor the progression of myopia during childhood.

3) Because treatment can be tailored to each child

Whether atropine eye drops should be used, as well as the appropriate concentration, is not determined in the same way for every child.

The treatment plan is established in consultation with an ophthalmologist after considering factors such as the child's age, current degree of myopia, rate of progression, axial length, and lifestyle habits.

5. Can Atropine Be Used Together with Orthokeratology Lenses?

Depending on the degree and progression of a child's myopia, treatments such as orthokeratology lenses, also known as Ortho-K lenses, or myopia-control soft contact lenses may be considered in addition to atropine.

These lenses can alter peripheral retinal defocus and may help slow axial elongation, while atropine works by modulating ocular growth.

Because the two treatments work through different mechanisms, combination therapy may provide greater myopia-control effects than either treatment alone.

At our clinic, an ophthalmologist directly evaluates the child's ocular measurements to determine the appropriate lens curvature and prescription.

We also offer a variety of brands and models, allowing us to select and fit lenses according to each child's individual needs.

In addition, children can try the lenses for approximately one week to allow time for adaptation before making a final decision about continued wear, helping reduce the burden associated with treatment.

6. What Should You Keep in Mind When Using Atropine Eye Drops?

If your child has been prescribed atropine eye drops, it is important to follow the dosage and frequency of administration recommended by the ophthalmologist.

Before applying the eye drops, wash your hands thoroughly. Be careful not to allow the tip of the medication bottle to come into direct contact with the eye, eyelids, or eyelashes.

Parents should not independently change the dosage, concentration, or frequency of administration, or discontinue treatment without consulting the ophthalmologist.

Regular follow-up examinations are important to monitor the progression of myopia and the child's response to treatment.

Some children may experience side effects such as increased sensitivity to light or difficulty with near vision. If discomfort persists or any unusual symptoms occur, it is recommended to consult an ophthalmologist.

Haengsin-dong Ophthalmology in Goyang: SMILE vs. 2-Day LASEKKey Differences, Advantages, and Disadvantages at a Glance

eyessg — Tue, 15 Sep 2026 17:15:51 +0900

Hello,
This is Goyang Shinsegae Eye Clinic.

When exploring vision correction surgery, you may come across more treatment options than expected.

Among the procedures most commonly compared are SMILE and 2-Day LASEK.

Both procedures aim to improve vision by correcting refractive errors such as myopia and astigmatism. However, there are clear differences in the way each procedure reshapes the cornea.

If you are comparing SMILE vs. 2-Day LASEK, it is important to look beyond cost and recovery time.

Understanding how each procedure reshapes the cornea and what type of laser system is used can also help you make a more informed decision.

So, what are the main differences between these two procedures, and what are the advantages and disadvantages of each?

1. How Does Laser Vision Correction Work?

The cornea plays an important role in bending, or refracting, incoming light so that it can focus properly on the retina.

When a refractive error such as myopia or astigmatism is present, light does not focus precisely on the retina, which can cause blurred vision.

Laser vision correction works by changing the refractive power of the cornea so that light can focus more accurately.

However, the method used to access and reshape the cornea varies depending on the type of procedure.

For this reason, it is important to understand the characteristics of each surgical approach before making a decision.

2. SMILE vs. 2-Day LASEK

1) What Is SMILE?

SMILE is a vision correction procedure that uses a femtosecond laser to create a thin, lens-shaped piece of tissue called a lenticule within the corneal stroma.

The surgeon then removes this lenticule through a small incision.

Unlike conventional LASIK, SMILE does not require the creation of a large corneal flap.

One of its main advantages is that postoperative discomfort is generally limited, while initial visual recovery tends to be relatively fast.

For this reason, SMILE is often considered by patients who want to return to their daily routines relatively quickly.

However, SMILE is not suitable for every patient.

Before surgery, factors such as corneal thickness and shape, as well as the degree of myopia and astigmatism, must be carefully evaluated.

During the procedure, the eye is stabilized using suction while the laser treatment is performed.

If the patient makes a significant eye movement or fixation is lost during this process, a suction loss may occur.

Therefore, a thorough preoperative examination is important to determine whether SMILE is appropriate for each individual.

In addition, the suction interface used during SMILE is disposable, and the cost of these single-use components may contribute to the overall treatment expense.

2) What Is 2-Day LASEK?

2-Day LASEK is a surface ablation procedure that uses an excimer laser to reshape the cornea.

It is based on the principles of conventional LASEK, but the cornea is treated without creating a corneal flap.

Because no separate flap is created, flap-related structural concerns do not need to be considered in the same way as with flap-based procedures.

This may be an advantage for people who regularly participate in sports or other activities where the eyes may be exposed to external impact.

For these patients, 2-Day LASEK may be one of the options worth considering.

3. Why Does the Laser System Matter in 2-Day LASEK?

At our clinic, we use the AMARIS RED excimer laser system.

AMARIS RED operates at a laser repetition rate of 1,050 Hz and uses 0.54 mm Gaussian Flying Spot technology.

Based on the planned ablation profile, the laser can precisely target the treatment area, allowing the epithelial removal zone to be reduced by approximately 40%.

The system also features real-time eye-tracking technology, which detects subtle eye movements during treatment and adjusts the laser position accordingly.

This helps maintain accurate laser delivery while minimizing unnecessary mechanical manipulation of the eye.

Depending on the individual healing process, many patients may be able to return to routine daily activities approximately 2 to 3 days after surgery.

4. How Should You Choose Between SMILE and 2-Day LASEK?

When comparing SMILE vs. 2-Day LASEK, it is difficult to say that one procedure is universally better than the other.

SMILE offers the clear advantage of relatively fast initial recovery.

2-Day LASEK, on the other hand, reshapes the cornea with an excimer laser without creating a corneal flap.

Rather than choosing a procedure based only on cost or recovery time, several factors should be evaluated first, including:

▶ Corneal thickness and shape
▶ Pupil size
▶ Degree of myopia and astigmatism
▶ Presence or severity of dry eye
▶ Lifestyle and daily activities

If you would like to avoid the creation of a corneal flap while considering vision correction with a precise excimer laser system, 2-Day LASEK may also be an option worth discussing with your ophthalmologist.

5. Postoperative Precautions

Whether you undergo SMILE or 2-Day LASEK, proper postoperative care is important to help the cornea heal and stabilize.

① Avoid rubbing your eyes

Do not rub your eyes or apply strong pressure to them during the early recovery period.

② Use prescribed eye drops as directed

Use all prescribed eye drops according to the recommended frequency and duration.

③ Keep water out of your eyes

During the initial healing period, take care to prevent water, soap, shampoo, or other cleansing products from entering the eyes while washing your face or showering.

④ Protect your eyes from UV exposure

Avoid excessive exposure to strong ultraviolet light and wear sunglasses when outdoors as recommended.

⑤ Attend scheduled follow-up examinations

Regular postoperative examinations are important for monitoring your vision and checking the condition of the cornea as it heals.

Ultimately, the most important factor in vision correction surgery is not choosing the procedure that is simply the most well-known.

A comprehensive eye examination should first be performed to assess your current eye condition.

Based on the results, your ophthalmologist can determine which surgical method and laser system may be most appropriate for your individual eyes.
