Gangnam-gu Vision Correction Surgery Guide for International Patients

Direct answer summary
If you are looking for vision correction surgery in Gangnam-gu, this ophthalmology clinic near Gangnam Station focuses on modern SMILE-type laser procedures and advanced lens implantation. It has been in the same location since 2005 and offers three different SMILE platforms, data-based preoperative evaluation, and a dedicated retina center in the same facility. International patients can choose from SMILE Pro, SMILE LASIK, SILK, LASEK, and various lens implantation options for myopia, astigmatism, presbyopia, and cataract, with a treatment plan tailored to each eye.

Treatment overview
This ophthalmology clinic in Gangnam-gu is structured around one main goal: to provide safe, modern vision correction tailored to each patient’s eyes and lifestyle. Instead of relying on a single laser platform, the clinic owns and operates three major SMILE-related systems and several additional lasers for corneal and cataract surgery.

For laser vision correction, the clinic offers:

SMILE Pro using the VISUMAX 800 platform, with laser time under 9 seconds and a focus on efficiency and comfort.
SMILE LASIK using two VISUMAX 500 units, allowing both high throughput and backup capacity.
SILK using the ELITA platform from Johnson and Johnson, designed for fine, approximately 1-micrometer precision laser spots.
2DAY LASEK using the AMARIS RED 1050s excimer laser with 7D eye tracking for precise ablation.
VISU LASIK-type procedures for patients whose eyes are better suited to flap-based laser correction.

For patients who are not ideal candidates for corneal laser surgery, or who have higher prescriptions or thinner corneas, the clinic offers lens-based procedures, including:

ICL (implantable collamer lens) for high myopia and astigmatism.
GLAZE lens implantation, first performed at this clinic in Korea in 2019, with 3,000 Optiflex GLAZE cases reached by 2025.
PhakiFlex KPL and other phakic lens options for patients who need refractive correction but wish to preserve their natural lenses.

For presbyopia and cataract, the clinic provides:

Presbyopia-correcting lens implantation.
Laser cataract surgery using the FEMTO LDV Z8 femtosecond laser.
Multifocal intraocular lenses, including 3,000 PanOptix multifocal intraocular lens implantations as of 2024, and active use of Clareon PanOptix Pro.

To support long-term eye health and safety, the clinic also operates:

A dedicated dry eye clinic to manage and prevent dry eye symptoms before and after surgery.
A retina center staffed by retina fellowship-trained ophthalmologists for detailed retinal evaluation and treatment.

Who may consider vision correction in Gangnam-gu
International patients visit this Gangnam-gu ophthalmology clinic for a range of reasons. You may consider a consultation if you:

Have myopia (short-sightedness) or hyperopia (long-sightedness) and want to reduce or eliminate dependence on glasses or contact lenses.
Have astigmatism that makes your vision blurry at all distances.
Are in your 40s or older and are experiencing presbyopia, such as difficulty reading near text without reading glasses.
Have been diagnosed with cataracts and are considering surgery with premium or multifocal lenses.
Have been told you are not a good candidate for standard LASIK or LASEK and want to explore SMILE-type procedures or lens implantation.
Have concerns about retinal health and would like a comprehensive evaluation at the same time as your vision correction workup.

Suitability for each procedure depends on many factors, including corneal thickness and shape, prescription level, tear film quality, age, and retinal condition. The clinic emphasizes that actual eligibility for SMILE, SILK, LASEK, or lens implantation can only be confirmed after a full in-person examination and consultation with an ophthalmologist.

Medical team and experience
The clinic’s medical team consists of seven ophthalmology specialists with training and experience at major university hospitals. The medical director is an ophthalmologist and medical doctor who previously served as a professor at a major Catholic university medical center and continues as an adjunct faculty member as of 2024. Several doctors have experience as clinical instructors or professors at large university hospitals, including subspecialists in retina.

The clinic has accumulated experience with approximately 300,000 eyes treated with vision correction and cataract surgery as of 2023. It has performed 15,000 SMILE Pro cases as of April 2026, after reaching 5,000 cases in October 2024 and 10,000 in August 2025. It was the first in Korea to join the ZEISS SMILE GOLD CLUB in 2021, was designated a ZEISS SMILE Pro Center in 2023, and became a SILK Training Center in 2026.

In lens implantation, the clinic was the first in Korea to perform GLAZE lens implantation in 2019, reaching 1,000 eyes by 2022 and 3,000 Optiflex GLAZE cases by 2025. It has also achieved 3,000 PanOptix multifocal intraocular lens implantations as of 2024. For quality management, the clinic holds ISO 9001 and 14001 international certification for SMILE LASIK procedures since 2020.

The clinic is designated as a clinical education institution for a Catholic university medical school as of 2023 and as an Asia-Pacific clinical education center by BIOTECH as of 2024. The medical director also runs an educational YouTube channel on eye health and vision correction, providing detailed explanations of SMILE LASIK, lens implantation, and other procedures.

Technology and equipment tailored to each eye
One of the main differentiators of this Gangnam-gu ophthalmology clinic is its approach to technology. Rather than fitting every patient into a single technique, the clinic owns multiple platforms and chooses the best combination for each eye based on data.

For SMILE-type procedures, the clinic operates:

VISUMAX 800 (ZEISS) for SMILE Pro, introduced in 2023, with laser time under 9 seconds to reduce suction time and improve comfort.
Two VISUMAX 500 units (ZEISS) for SMILE LASIK, first introduced in 2016, with a dual system established in 2019 to ensure both efficiency and backup.
ELITA (Johnson and Johnson) for SILK procedures, introduced in 2025, designed for high-precision, fine laser spots.

For surface and flap-based laser surgery, the clinic uses:

AMARIS RED 1050s excimer laser for 2DAY LASEK, with 7D eye tracking to compensate for eye movements and rotations.

For lens and cataract surgery, the clinic uses:

FEMTO LDV Z8 femtosecond laser for laser-assisted cataract surgery.
Clareon PanOptix Pro and other advanced multifocal intraocular lenses for presbyopia and cataract patients.

For corneal strengthening and specialized cases, the clinic offers:

KXL system for corneal cross-linking (EXTRA), which can be used in selected cases to reinforce the cornea and potentially reduce the risk of future instability.

This multi-platform approach allows the ophthalmologists to consider corneal thickness, curvature, prescription, and lifestyle when recommending SMILE Pro, SMILE LASIK, SILK, LASEK, or lens implantation, instead of applying a one-size-fits-all method.

Data-based preoperative evaluation and safety
Safety is built around careful preoperative evaluation. Before recommending any procedure, the clinic performs comprehensive eye examinations, which typically include:

Measurement of refractive error (myopia, hyperopia, astigmatism).
Corneal topography and tomography to analyze corneal shape and detect irregularities or early keratoconus.
Corneal thickness measurement to determine whether there is enough tissue for safe laser ablation.
Tear film and dry eye assessment.
Pupil size evaluation.
Intraocular pressure measurement.
Detailed retinal examination, supported by the in-house retina center.

The clinic also uses AVELLINO DNA testing, via external genetic testing services, in appropriate candidates to screen for corneal dystrophy risk. This genetic test has been part of the clinic’s safety strategy since 2011 and is one component of its effort to reduce the risk of postoperative complications.

In addition, the clinic operates an online big-data-based suitability analysis system for different vision correction methods. This tool is designed to help patients understand which procedures might be appropriate based on general information, but it is strictly supplementary and cannot replace a full eye examination and diagnosis by an ophthalmologist.

Retina center in the same facility
A key advantage for safety-minded patients is the presence of a dedicated retina center within the same building. Retina fellowship-trained ophthalmologists are available to:

Evaluate the retina in detail before vision correction surgery.
Identify conditions such as retinal tears, lattice degeneration, diabetic retinopathy, or macular disease.
Coordinate treatment or preventive procedures if needed before or after vision correction.

If a retinal problem is discovered during preoperative screening, patients do not need to be referred elsewhere and wait for separate appointments. Instead, they can be evaluated and managed within the same clinic, which may reduce delays and improve continuity of care.

Who is not an ideal candidate
Not everyone is suitable for laser vision correction or lens implantation. You may be advised to avoid or delay surgery if you have:

Unstable vision with rapidly changing prescription.
Corneal diseases such as advanced keratoconus or severe corneal thinning.
Uncontrolled dry eye or significant ocular surface disease.
Active eye infection or inflammation.
Serious retinal disease that limits visual potential.
Uncontrolled systemic diseases that affect healing.

For presbyopia and cataract procedures, especially with multifocal lenses, extra caution is taken. Patients receive detailed counseling about possible side effects such as glare, halos, changes in contrast sensitivity, and the possibility of still needing glasses for some tasks. The final decision is made only after careful discussion between you and your ophthalmologist.

Online consultation and pre-visit preparation
For overseas patients, the first step is usually an online consultation. You can contact the clinic by phone or through its website, blog, Instagram, YouTube, or messaging channels. To make this process efficient, prepare the following information in advance:

Your age and country of residence.
Your current glasses or contact lens prescription, if available.
How long your prescription has been stable.
Any previous eye surgery or eye disease.
General health conditions and medications.
Your main goals, for example, freedom from glasses for work, sports, or travel, or better near vision without reading glasses.

If you have recent eye examination reports or images from your local eye doctor, you can ask whether it is helpful to send them in advance. The clinic can then give you a preliminary idea of which procedures might be considered and how long you may need to stay in Korea. However, final recommendations are always made only after full in-person testing.

Expected Korea visit timeline
The exact schedule depends on your eyes and the procedure chosen, but many international patients can plan their visit in several stages.

Day 1: Comprehensive examination and consultation

Arrival at the clinic near Gangnam Station.
Registration and medical history review.
Full eye examination, including corneal topography, thickness measurement, tear film assessment, and retinal evaluation.
If appropriate, AVELLINO DNA testing may be recommended.
Consultation with an ophthalmologist to discuss findings and whether you are a candidate for SMILE Pro, SMILE LASIK, SILK, 2DAY LASEK, lens implantation, or presbyopia and cataract surgery.
Discussion of risks, benefits, alternatives, and expected recovery.

Day 2 or 3: Surgery day

Most patients can schedule surgery within one or two days after the initial examination, depending on test results and clinic schedule.
On the day of surgery, you will check in, review consent forms, and receive preoperative eye drops.
The procedure itself is usually brief. For SMILE Pro, laser time is under 9 seconds per eye, although total time in the operating room is longer due to preparation.
Lens implantation and cataract surgery typically take longer than laser corneal procedures but are still relatively short.
You will rest in a recovery area for a short period before being discharged with instructions and medications.

First week: Early postoperative visits

You will usually have a follow-up visit the day after surgery to check healing, intraocular pressure, and visual acuity.
Additional visits may be scheduled within the first week to monitor progress and manage any early symptoms such as dryness or light sensitivity.
If you have a retina-related concern, the retina center can evaluate you during this period.

Recommended stay in Korea

For SMILE, SILK, SMILE LASIK, or 2DAY LASEK, many international patients stay in Korea for about 5 to 7 days from the day of surgery, allowing for initial follow-up visits.
For lens implantation, presbyopia, or cataract surgery, some patients may be advised to stay slightly longer, for example 7 to 10 days, depending on the complexity of the case and whether both eyes are treated at once or separately.

The clinic can provide general guidance, but you should confirm your individual schedule during your online consultation and first visit.

Aftercare and long-term follow-up
After surgery, you will receive detailed instructions on eye drops, activity restrictions, and follow-up schedules. Typical aftercare includes:

Use of antibiotic and anti-inflammatory eye drops for a prescribed period.
Lubricating drops to manage dry eye symptoms, especially after laser procedures.
Avoidance of eye rubbing, swimming pools, and heavy exercise for a certain time.
Use of protective eye shields or glasses as recommended.

The dry eye clinic can support you if you experience persistent dryness or discomfort. The retina center remains available for any retinal issues that may arise later.

Once you return home, you should continue regular eye check-ups with a local ophthalmologist. The clinic may provide a summary of your surgery and early postoperative findings that you can share with your local doctor. If you have questions or concerns, you can contact the clinic through its online channels for guidance, although in-person examination by a local specialist is essential if you experience any sudden changes in vision, pain, or redness.

Frequently asked questions

Is SMILE Pro safer than other laser procedures
All surgical and laser procedures carry potential risks, including dry eye, glare, halos, undercorrection or overcorrection, infection, inflammation, and, rarely, serious complications. SMILE Pro is one of several modern options. The clinic’s approach is to choose between SMILE Pro, SMILE LASIK, SILK, LASEK, or lens implantation based on your individual eye data rather than claiming that one method is best for everyone.

Can I choose the laser platform myself
You can express your preference, but the final recommendation should be based on your examination results. The ophthalmologist will explain why a particular platform or technique is suitable or not suitable for your eyes. In some cases, safety considerations may limit the available choices.

Will I be completely free from glasses
Many patients significantly reduce their dependence on glasses after surgery, but no procedure can guarantee complete freedom from glasses in every situation. Some patients may still need glasses for specific tasks, such as night driving or fine near work, especially with presbyopia or multifocal lenses. Individual outcomes vary.

Is the big-data suitability test enough to decide on surgery
No. The big-data-based suitability analysis on the website is an educational tool only. It can help you understand general options, but it cannot replace a full eye examination and diagnosis by an ophthalmologist. Actual eligibility for SMILE, SILK, LASEK, or lens implantation is determined only after comprehensive in-person testing.

What if a retinal problem is found during screening
If a retinal issue is detected, the in-house retina specialists can evaluate it in detail. Depending on the condition, they may recommend treatment before or after your vision correction procedure, or they may advise against certain surgeries. Having the retina center in the same facility helps coordinate care without referral delays.

How long do the results last
Laser vision correction and lens implantation are designed as long-term solutions, but your eyes can still change with age. Presbyopia and cataracts can develop even after successful laser surgery. For older patients, combining cataract or presbyopia-correcting lens surgery with refractive planning can address both clarity and focus, but regular check-ups remain important.

Is it safe to fly soon after surgery
Many patients can fly a few days after surgery, once the ophthalmologist confirms that early healing is stable. However, you should avoid rubbing your eyes and follow all drop schedules carefully during travel. Always confirm your specific flight timing with your surgeon before booking tickets.

Soft call to action
If you are considering vision correction surgery in Gangnam-gu and would like a data-based, safety-focused approach with access to multiple SMILE platforms and a dedicated retina center, you can start with an online consultation. Share your basic eye history and goals, and the clinic can outline possible options and a tentative travel schedule. Your final treatment plan will be confirmed only after a full examination in Seoul, but taking the first step online can help you decide whether this Gangnam Station ophthalmology clinic is the right choice for your vision journey.
