Direct answer summary
If you are searching for an eye clinic near Yangjae Station that offers SMILE, SILK, and lens implantation with a university-hospital-level team, GS Eye Clinic in the Gangnam Station area is one option to consider. Opened in 2005 and operating in the same building on Gangnam-daero since then, it focuses on SMILE-based laser vision correction, presbyopia and cataract surgery, and has an in-house retina center. The clinic is convenient for patients using both Yangjae Station and Gangnam Station and is set up to support international visitors who want thorough examinations, advanced equipment, and structured follow-up.

Clinic overview near Yangjae and Gangnam
GS Eye Clinic is an ophthalmology clinic that has been in the Gangnam Station area since 2005, later rebranded under its current name. It occupies multiple floors of a commercial building on Gangnam-daero, making it easy to reach from Yangjae Station, Gangnam Station, and nearby office districts.

The clinic’s philosophy is to focus on skill, careful decision-making, and long-term safety rather than flashy marketing. It is run by a board-certified ophthalmologist with a medical doctorate who is active in education and online communication, including a YouTube channel about eye health and vision correction.

Only ophthalmology specialists provide care here, with a team of seven eye doctors. Several have backgrounds as professors or clinical instructors at major university hospitals in Seoul. Dedicated retina specialists work in a separate retina center within the clinic, so retinal issues discovered during screening for laser vision correction or cataract surgery can usually be handled without referring you elsewhere.

Key focus areas The clinic’s main strengths are:

1. SMILE-based laser vision correction, including SMILE Pro, SMILE LASIK, and SILK (Silk LASIK)
2. Lens-based procedures such as ICL, GLAZE, and other phakic lens implantations
3. Presbyopia and cataract surgery, including laser cataract surgery and premium multifocal intraocular lenses
4. A dedicated retina clinic for diagnosis and treatment of retinal diseases
5. A dry eye clinic and corneal cross-linking for patients with corneal or tear film issues

Treatment overview: vision correction options

SMILE Pro and SMILE LASIK
SMILE (Small Incision Lenticule Extraction) is a flapless laser vision correction method that reshapes the cornea through a small incision. GS Eye Clinic has made SMILE a core focus and operates a dedicated SMILE operating room.

The clinic uses three major SMILE-related platforms:

VISUMAX 800 for SMILE Pro: This ZEISS femtosecond laser, introduced at the clinic in 2023, offers high-speed treatment with laser times under about 10 seconds for many cases. Shorter laser times may help with comfort and stability during the procedure.

VISUMAX 500 for SMILE LASIK: The clinic operates two VISUMAX 500 units, creating a dual system since 2019. This supports both case volume and redundancy, so if one unit is under maintenance, the other can be used.

These systems are used for SMILE LASIK procedures tailored to different corneal shapes, degrees of myopia, and astigmatism.

SILK (Silk LASIK)
SILK is another form of flapless laser vision correction that uses the ELITA laser platform from Johnson and Johnson. The clinic introduced ELITA in 2025. ELITA uses an approximately 1-micrometer precision laser spot, designed for fine corneal sculpting.

SILK may be suggested for patients whose corneal shape or lifestyle fits better with this platform than with classic SMILE. The choice between SMILE Pro, SMILE LASIK, and SILK is usually made after detailed measurements of corneal thickness, curvature, and biomechanical properties.

LASEK and customized excimer procedures
For patients who are not ideal candidates for SMILE or SILK, surface procedures such as LASEK are available. GS Eye Clinic uses the AMARIS RED 1050s excimer laser, which has 7-dimensional eye tracking to help maintain accuracy even with small eye movements.

The clinic also offers a fast-recovery protocol branded as 2DAY LASEK, designed to shorten the most uncomfortable period after surface ablation. Whether this is appropriate depends on your corneal profile and lifestyle.

Lens implantation options: ICL, GLAZE, PhakiFlex KPL
Some patients have high myopia, thin corneas, or other conditions that make laser vision correction less suitable. For these cases, lens implantation (phakic intraocular lenses) is another option.

The clinic provides:

1. ICL (Implantable Collamer Lens)
2. GLAZE lens implantation, including Optiflex GLAZE
3. PhakiFlex KPL and similar phakic lens procedures

GS Eye Clinic was the first in Korea to perform GLAZE lens implantation in 2019. By 2022, they had reached 1,000 GLAZE eyes, and by 2025, approximately 3,000 Optiflex GLAZE cases. These numbers give a sense of accumulated experience with this specific lens type.

Corneal cross-linking and dry eye clinic
For patients with borderline corneal strength or early ectatic tendencies, corneal cross-linking (EXTRA / KXL) can be used to enhance biomechanical stability. The clinic uses the KXL system for this purpose.

A dry eye clinic supports patients who have tear film or ocular surface problems before or after surgery. Managing dry eye can be important for both visual quality and comfort, especially after laser vision correction.

Presbyopia and cataract surgery

Presbyopia lens implantation
For patients in their 40s and beyond who are tired of reading glasses, presbyopia lens implantation can be considered. This usually involves replacing the natural lens with a multifocal or extended-depth-of-focus intraocular lens (IOL) to reduce dependence on glasses for both near and distance.

Laser cataract surgery
For cataract and presbyopia cases, GS Eye Clinic uses the FEMTO LDV Z8 femtosecond laser. This allows certain steps of cataract surgery to be performed by laser, such as corneal incisions and lens fragmentation, aiming for more precision and consistency.

Multifocal intraocular lenses
The clinic uses a range of multifocal IOLs, including widely used premium lenses such as PanOptix and newer models like Clareon PanOptix Pro. Around 3,000 PanOptix multifocal lens implantations had been performed as of 2024.

Lens choice is highly individual. Factors such as night driving, computer work, reading habits, and tolerance for possible halos or glare are considered during counseling.

Important note on risks and side effects
Presbyopia and cataract surgeries, including multifocal lens implantation, can involve side effects. These may include glare, halos, reduced contrast sensitivity, dry eye, infection, inflammation, or the need for additional procedures such as enhancements or lens exchange. Individual results vary, and not everyone will achieve full spectacle independence.

Retina clinic and safety

In-house retina center
GS Eye Clinic has a separate retina center staffed by fellowship-trained retina specialists. This allows comprehensive evaluation of the retina before vision correction or cataract surgery, and treatment of conditions such as retinal tears, diabetic retinopathy, or macular disease.

If a retinal issue is found during your preoperative exam, it can often be addressed in the same clinic, which is convenient for international patients with limited time in Korea.

AVELLINO DNA testing and screening
The clinic emphasizes complication prevention through thorough screening. Since 2011, it has used AVELLINO DNA testing via an external laboratory to detect genetic corneal dystrophies that can increase risk with certain laser procedures.

Extensive preoperative examinations include corneal shape and thickness, tear film assessment, intraocular pressure, and detailed retina evaluation. The goal is to identify patients who are not suitable for particular procedures and suggest safer alternatives.

Track record and educational roles

Surgical volume and milestones
As of 2023, the clinic reports a cumulative total of approximately 300,000 eyes treated with vision correction and cataract surgery. For SMILE Pro specifically, they report:

1. ,000 eyes by October 2024
2. ,000 eyes by August 2025
3. ,000 eyes by April 2026

These figures indicate that SMILE-based procedures are a major part of the clinic’s practice.

Designations and certifications
The clinic has received several designations related to SMILE and lens technology:

1. Joined the ZEISS SMILE Gold Club in 2021 (first in Korea)
2. Designated as a ZEISS SMILE Pro Center in 2023
3. Designated as a SILK Training Center in 2026
4. Obtained ISO 9001 and 14001 international standards for SMILE LASIK in 2020
5. Designated as a clinical education institution by a major medical school in 2023
6. Named an Asia-Pacific clinical education center by BIOTECH in 2024

These roles reflect active participation in clinical education and technology adoption, though they do not guarantee specific results for individual patients.

Who may consider this clinic

Suitable patient profiles
GS Eye Clinic near Yangjae and Gangnam Stations may be suitable if you:

Plan to stay in Seoul and want an eye clinic easily accessible from Yangjae Station, Gangnam Station, or nearby business districts
Are considering SMILE, SILK, or LASEK for myopia and astigmatism
Have high myopia or thin corneas and are exploring ICL, GLAZE, or other phakic lens implantation
Are in your 40s or older and want presbyopia or cataract surgery with multifocal IOL options
Prefer a clinic with in-house retina specialists for comprehensive evaluation
Value detailed explanations and educational content before deciding

Who should be cautious
You should discuss your situation very carefully with the medical team if you:

1. Have uncontrolled diabetes, autoimmune disease, or severe dry eye
2. Have a history of keratoconus, corneal ectasia, or significant corneal scars
3. Are pregnant or breastfeeding
4. Have advanced glaucoma or serious retinal disease
5. Have unrealistic expectations about perfect vision without glasses in all situations

In such cases, the clinic may recommend postponing surgery, choosing a more conservative procedure, or continuing with glasses or contact lenses.

Online consultation and pre-visit preparation

Using online channels
Before traveling to Korea, you can usually contact the clinic through its website, blog, social media, or messaging app. Many international patients start with:

Sending recent prescriptions or eye exam data (if available)
Explaining their main goals, such as reducing dependence on glasses for distance, near, or both
Sharing any known diagnoses, such as dry eye, keratoconus, or retinal problems

The clinic also operates an educational YouTube channel where you can learn about SMILE, SILK, ICL, cataract surgery, and presbyopia in more detail.

Big-data suitability tool
On the clinic website, there is a big-data-based suitability analysis system. By entering basic information such as age, prescription range, and lifestyle, you can get a rough idea of which procedures might fit you.

It is essential to understand that this tool is for reference only. It does not replace a medical examination or formal diagnosis. Final decisions can only be made after in-person tests and consultation with an ophthalmologist.

Documents and information to prepare Before your visit, prepare:

1. Passport and travel details
2. List of current medications and medical conditions
3. History of eye surgeries, infections, or injuries
4. Contact lens history (type and how many years you have worn them)
5. Any previous eye exam records or topography reports, if available

You should also stop wearing soft contact lenses for several days before your exam, and rigid or orthokeratology lenses for a longer period, according to the clinic’s instructions. This helps ensure accurate corneal measurements.

Expected Korea visit timeline for international patients

Short-stay plan for laser vision correction
For SMILE, SILK, or LASEK, many overseas patients plan a stay of about 5 to 10 days in Seoul. A typical schedule might look like this (exact timing depends on your case and the clinic’s advice):

Day 1: Comprehensive eye examination and consultation. This includes vision tests, corneal topography, thickness measurement, tear film assessment, and retina check. If you are a suitable candidate and feel comfortable, you may schedule surgery within the next 1 to 2 days.

Day 2 or 3: Surgery day. SMILE and SILK procedures are usually quick, often taking less than 20 minutes in the operating room. You will rest briefly at the clinic after surgery and then return to your accommodation with protective shields and eye drops.

Day 3 or 4: First postoperative check. The doctor confirms corneal condition, checks for inflammation, and adjusts your eye drop schedule.

Day 5 to 7: Additional follow-up visit, especially important for LASEK or if you have dry eye or borderline corneal features.

If you are staying longer in Korea, the clinic may suggest further follow-up at 2 to 4 weeks. If you must leave earlier, you will receive instructions for follow-up with an eye doctor in your home country.

Visit plan for cataract or presbyopia surgery
For presbyopia or cataract surgery with multifocal lenses, many patients plan at least 7 to 14 days in Seoul, particularly if both eyes will be treated. A typical outline:

Day 1: Detailed examination and counseling, including biometry for IOL power calculation, corneal measurements, and retina evaluation.

Day 2 or 3: Surgery for the first eye using laser-assisted cataract surgery if indicated.

Day 3 to 5: Early follow-up for the first eye.

Day 5 to 7: Surgery for the second eye (timing varies by case and surgeon preference).

Day 8 to 14: Follow-up visits for both eyes, adjustment of medications, and assessment of visual function at different distances.

Because presbyopia and cataract surgeries can involve adaptation to multifocal optics, it is wise to allow enough time in Korea to address early issues such as halos, glare, or imbalance between eyes.

Aftercare and long-term follow-up

Immediate postoperative care
After SMILE, SILK, or LASEK, you will typically receive:

1. Antibiotic and anti-inflammatory eye drops for several days to weeks
2. Lubricating drops to manage dryness and improve comfort
3. Eye shields or protective glasses, especially during sleep

You will be advised to avoid rubbing your eyes, swimming pools, saunas, and heavy exercise for a certain period. Screen time and reading may be limited for the first day or two, especially after LASEK.

For cataract and presbyopia surgery, a similar drop regimen is used, often for a few weeks. You will be monitored for intraocular pressure, inflammation, and lens position.

Medium- and long-term follow-up If you live overseas, the clinic may suggest:

A check-up with your local eye doctor within a few weeks of returning home
Annual eye examinations to monitor corneal stability, retina health, and intraocular pressure

If you experience sudden vision loss, flashes of light, a curtain-like shadow, or severe pain after returning home, you should seek emergency eye care immediately and then contact the clinic with your records.

Frequently asked questions

Is SMILE or SILK better for me?
There is no single best procedure for everyone. SMILE Pro, SMILE LASIK, and SILK each have technical differences in laser platform and corneal interaction. The clinic will recommend one based on your prescription, corneal thickness and curvature, pupil size, lifestyle, and expectations. A full examination is necessary before deciding.

Can I have surgery during a short business trip to Seoul?
Many patients who work in the Gangnam and Seocho areas schedule exams and surgery around their work. For international visitors, a stay of at least 5 to 7 days is usually recommended for SMILE or SILK, and longer for cataract or presbyopia surgery. If your schedule is very tight, discuss this in advance through online consultation.

Are the results guaranteed?
No medical or surgical result can be guaranteed. While the clinic has extensive experience and advanced equipment, individual healing responses vary. Some patients may need enhancement procedures, continued glasses for certain tasks, or may experience side effects such as halos or dry eye.

What are the main risks of laser vision correction?
Potential risks include undercorrection or overcorrection, dry eye, glare or halos at night, inflammation, infection, regression of effect, and in rare cases, corneal ectasia. Thorough screening, including AVELLINO DNA testing and corneal topography, is used to reduce these risks, but they cannot be completely eliminated.

What are the main risks of presbyopia and cataract surgery?
Risks include infection, inflammation, elevated eye pressure, glare, halos, reduced contrast sensitivity, retinal detachment, macular edema, and the need for additional surgery or lens exchange. Multifocal lenses can cause visual phenomena that some patients find bothersome. It is important to discuss these in detail and weigh them against the benefits of reduced dependence on glasses.

How does the clinic support foreign patients?
Although this is primarily a local clinic for residents near Yangjae and Gangnam Stations, many international patients visit due to its focus on SMILE, SILK, and lens implantation. Staff are accustomed to explaining procedures clearly, and the clinic provides educational content online. You can usually coordinate your schedule and basic questions via email or messaging apps before you arrive.
