Gangnam SMILE LASIK Guide for International Patients

Direct answer summary
If you are searching for Gangnam SMILE LASIK, this ophthalmology clinic near Gangnam Station offers a full range of SMILE vision correction options in one place. The clinic focuses on SMILE LASIK and next‑generation SMILE procedures using three major femtosecond laser platforms: ZEISS VisuMax 800 for SMILE pro, ZEISS VisuMax 500 for classic SMILE LASIK, and Johnson & Johnson ELITA for SILK. Instead of fitting every patient into a single standard procedure, the medical team evaluates your eyes and lifestyle, then recommends a laser and technique that match your cornea and visual needs.

The clinic has been in the same building near Gangnam Station since 2005, focusing on vision correction and cataract care. All seven doctors are ophthalmologists with board certification, many with university hospital and retina subspecialty backgrounds. As of 2023, the clinic has accumulated around 300,000 eyes of vision correction and cataract surgery, including about 15,000 SMILE pro eyes as of April 2026. For overseas patients, the clinic provides detailed preoperative screening, structured processes certified to ISO 9001 and 14001 standards for SMILE LASIK, and an organized follow‑up system.

What is SMILE LASIK
SMILE LASIK is a type of laser vision correction designed to reduce dependence on glasses or contact lenses, mainly for myopia and astigmatism. SMILE stands for Small Incision Lenticule Extraction. Instead of creating a large flap on the cornea, a femtosecond laser creates a small lens‑shaped piece of tissue (lenticule) inside the cornea and a tiny incision. The surgeon then removes this lenticule through the small opening, reshaping the cornea to improve focus.

How SMILE differs from LASIK and LASEK
Traditional LASIK uses a flap on the surface of the cornea. The flap is lifted, an excimer laser reshapes the cornea, and the flap is placed back. LASEK and similar surface procedures remove the surface epithelium, then use an excimer laser on the exposed cornea, and the surface layer grows back over time.

SMILE is different in several ways:

It uses a small incision instead of a large flap.
It relies on a femtosecond laser alone, without a separate excimer laser for the main correction.
The corneal surface remains more intact compared with flap‑based procedures.

Potential advantages of SMILE include a smaller incision, which may help maintain more corneal biomechanical strength, and many patients report less dry eye symptoms compared with some flap‑based procedures. Recovery is usually relatively quick, and many people can return to daily activities within a few days, depending on individual healing and the surgeon’s instructions.

However, SMILE is not ideal for everyone. Some patients with very high prescriptions, very thin corneas, irregular corneas, certain corneal diseases, or specific occupational or lifestyle needs may be better suited to other procedures such as LASEK, phakic lens implantation, or lens‑based surgery. A thorough examination and consultation are essential before any decision.

SMILE options at this Gangnam clinic
This Gangnam ophthalmology clinic focuses strongly on SMILE‑type procedures and offers a full SMILE lineup in one place:

1. SMILE pro using ZEISS VisuMax 800
2. Classic SMILE LASIK using ZEISS VisuMax 500
3. SILK using Johnson & Johnson ELITA
4. The clinic’s own branded Golden SMILE concept

SMILE pro with VisuMax 800 is a newer generation of SMILE technology that can offer faster laser time and refined features compared with earlier platforms. Classic SMILE LASIK with VisuMax 500 is the original, widely used SMILE technique that has been performed internationally for many years. SILK, performed with the ELITA laser, is another small‑incision lenticule‑based procedure designed to refine the corneal shape through a minimally invasive approach.

The Golden SMILE concept is the clinic’s way of combining detailed preoperative analysis with the choice of platform and technique. Rather than assuming that one laser is best for everyone, the doctors consider corneal thickness, curvature, tear film, pupil size, retina status, and lifestyle factors such as night driving, sports, or screen use. Based on this, they recommend SMILE pro, classic SMILE, SILK, or, when more suitable, a different type of vision correction.

Why equipment choice matters
Many clinics offer only one SMILE platform. This Gangnam clinic owns and operates multiple major systems:

1. ZEISS VisuMax 800 for SMILE pro
2. Two ZEISS VisuMax 500 units for SMILE LASIK
3. Johnson & Johnson ELITA laser for SILK
4. Additional excimer lasers for other laser procedures
5. Cataract lasers for lens and cataract surgery

Having all three major SMILE‑related femtosecond platforms allows the doctors to select the laser and technique that best match each patient’s cornea and visual goals, instead of adjusting the patient to fit a single machine. For example, some corneal shapes or thickness profiles may be more suitable for a particular platform or treatment pattern. Some patients may prioritize speed and comfort on the day of surgery, while others may focus on certain optical characteristics.

The clinic has been recognized by ZEISS as a SMILE Gold Club member in 2021 and designated as a SMILE pro Center in 2023. It was also designated as a SILK Training Center in 2026. These are formal designations from the manufacturers and reflect the clinic’s experience with these technologies and its role in training other doctors.

The clinic’s long‑term focus and medical team
This is an ophthalmology clinic, not a general hospital. It has operated in the same location near Gangnam Station since 2005, focusing on vision correction and cataract care. This continuity can be reassuring for international patients who want a stable, established center rather than a newly opened facility.

All seven doctors are board‑certified ophthalmologists. Many of them have university hospital backgrounds and subspecialty training, particularly in the retina. This means that both the front of the eye (cornea, lens, tear film) and the back of the eye (retina, macula, optic nerve) can be evaluated and treated in‑house.

As of 2023, the clinic has accumulated around 300,000 eyes of vision correction and cataract surgery. Within that, approximately 15,000 SMILE pro eyes had been performed by April 2026. These numbers indicate a high volume of refractive and cataract experience over many years, though they do not guarantee outcomes for any individual.

The clinic is also designated as a clinical education site for a medical school since 2023 and as an Asia‑Pacific clinical education center for a biotech company since 2024. The medical director holds a medical doctorate, has experience as former university hospital faculty, and works as adjunct faculty. He also produces educational content on video platforms to explain eye conditions and procedures to the public. These roles support the clinic’s image as a teaching and training hub for ophthalmology.

Safety systems and preoperative screening
For SMILE LASIK and related procedures, the clinic emphasizes detailed preoperative screening and structured processes.

Separate SMILE operating room
The clinic operates a separate SMILE‑only operating room. This allows the staff to maintain a dedicated environment for SMILE procedures, with equipment and workflows tailored to this type of surgery.

ISO 9001 and 14001 certified processes
The clinic’s SMILE LASIK processes have been certified under ISO 9001 and 14001 since 2020. ISO 9001 relates to quality management systems, and ISO 14001 relates to environmental management systems. For patients, this means the clinic follows standardized, documented procedures for SMILE LASIK and manages its environment and processes in a structured way. These certifications do not eliminate risks but show that the clinic’s systems are regularly reviewed and audited.

Extensive eye examinations
Before recommending SMILE LASIK, the clinic performs detailed eye examinations, which typically include:

1. Measurement of refractive error (degree of myopia, hyperopia, astigmatism)
2. Corneal thickness and shape (topography and tomography)
3. Tear film and dry eye evaluation
4. Pupil size and response
5. Intraocular pressure
6. Lens status
7. Retina and optic nerve examination, often with imaging

If any retinal abnormalities are found during SMILE screening, in‑house retina specialists can evaluate and manage them. This may be especially important for patients with high myopia, diabetes, or other conditions that increase the risk of retinal problems. In some cases, retinal treatment or monitoring may be recommended before or instead of vision correction surgery.

AVELLINO DNA testing
Since around 2011, the clinic has used AVELLINO DNA testing, an outsourced genetic test, as part of its screening for certain corneal dystrophies before laser vision correction. Some inherited corneal conditions can increase the risk of complications after laser surgery. DNA testing can help identify some of these conditions in advance.

It is important to understand that AVELLINO testing is one tool among many and does not guarantee zero risk. It can reduce the chance of performing laser surgery on patients with certain genetic corneal issues, but other factors and conditions still need to be assessed through clinical examination and imaging.

Big data based online suitability analysis
The clinic offers an online suitability analysis system based on accumulated clinical data. International patients can enter basic information such as age, prescription range, and eye history. The system then suggests which procedures might be worth discussing, such as SMILE pro, classic SMILE, SILK, LASEK, or lens implantation.

This tool is designed as a starting point for education and expectation setting. It does not replace an in‑person examination. Final decisions must always be made after a full eye exam and consultation with an ophthalmologist.

Who may consider SMILE LASIK in Gangnam
You may consider SMILE LASIK at this Gangnam clinic if:

You are an adult with stable myopia or myopic astigmatism.
You want to reduce dependence on glasses or contact lenses.
You prefer a small‑incision procedure rather than a flap‑based surgery.
You are planning a trip to Seoul and want to combine travel with vision correction.

However, you may not be a candidate if you have:

1. Very thin or irregular corneas
2. Keratoconus or other corneal diseases
3. Uncontrolled dry eye disease
4. Certain autoimmune or systemic conditions
5. Unstable prescription
6. Significant cataract or presbyopia that would be better treated with lens‑based surgery

The only way to know for sure is to undergo a full preoperative examination. For some patients, the safest and most effective option may be a different procedure.

From online consultation to surgery: typical patient journey
For overseas patients, planning and timing are important. Here is a general outline of what the journey might look like.

1. Online consultation and pre‑visit preparation

Use the clinic’s online consultation or suitability analysis tool to share your age, prescription, and basic medical history.
Send recent glasses or contact lens prescriptions, and if available, previous eye exam reports.
Discuss your travel dates, so the clinic can advise on the best timing for examination, surgery, and follow‑up.
Inform the clinic about any general health issues, medications, or previous eye surgeries.

The clinic will usually respond with preliminary guidance on whether you might be a candidate for SMILE LASIK or whether alternative procedures should be considered. This is not a final decision but helps you plan your trip.

2. First visit in Korea: full examination and counseling

Most international patients schedule a full day or at least a half day for the first in‑clinic visit. During this visit, you can expect:

Comprehensive eye exams including refraction, corneal imaging, tear film tests, and retinal evaluation.
Discussion of your daily activities, work, sports, and night driving habits.
Review of all findings by an ophthalmologist.
Explanation of suitable options, such as SMILE pro, classic SMILE, SILK, or other procedures.
Discussion of risks, benefits, alternatives, and expected recovery.

If you are a suitable candidate and decide to proceed, surgery can sometimes be scheduled within a short period, depending on your eye condition and travel schedule. Some patients have surgery the next day; others may wait a few days.

3. Surgery day

On the day of SMILE LASIK, you will typically:

Arrive at the clinic with no eye makeup and follow any instructions about contact lens discontinuation.
Have final checks and measurements.
Receive anesthetic eye drops to numb the eyes.
Undergo the SMILE procedure in the dedicated SMILE operating room.

The laser time itself is usually short, but you should plan to spend several hours at the clinic for preparation and post‑operative checks. After the procedure, your vision may be hazy, and you will need someone to accompany you or plan safe transportation back to your accommodation.

4. Early follow‑up in Korea

Most patients have a follow‑up visit the next day to check healing, confirm corneal status, and review medication instructions. Additional follow‑up visits may occur a few days later, depending on your schedule and the doctor’s recommendation.

For many international patients, a stay of about one to two weeks in Korea allows for surgery and the early follow‑up period. The exact duration depends on your eyes, the procedure, and your travel flexibility.

Aftercare and long‑term follow‑up
After SMILE LASIK, you will usually use eye drops for several weeks to months, including antibiotics and anti‑inflammatory drops in the early period, followed by lubricating drops as needed.

Typical aftercare guidance may include:

Avoid rubbing your eyes.
Use prescribed drops exactly as instructed.
Avoid swimming pools, hot tubs, and heavy eye makeup for a certain period.
Wear protective eyewear or shields if recommended, especially during sleep in the early days.
Limit intense exercise and contact sports for a time, based on your doctor’s advice.

Once you return to your home country, you should continue regular eye checkups with a local eye doctor. The Gangnam clinic can often provide a summary of your procedure and early postoperative findings for your local doctor. If you notice unusual pain, sudden vision changes, or other concerning symptoms, you should seek prompt evaluation.

Other options if SMILE is not suitable
Not everyone is a candidate for SMILE LASIK. This clinic offers a wide range of alternative procedures, which can be helpful for complex cases or for patients with specific needs.

These options include:

1. Phakic lens implantation such as ICL, GLAZE, and PhakiFlex KPL
2. LASEK and other surface laser procedures
3. Corneal cross‑linking for certain corneal conditions
4. Presbyopia lens surgery
5. Laser cataract surgery
6. Multifocal intraocular lenses

The clinic was the first in Korea to perform GLAZE lens implantation in 2019 and had reached several thousand GLAZE cases by 2025. This experience supports its refractive expertise, especially for patients with high myopia or thin corneas who may not be ideal candidates for corneal laser procedures.

For older patients with significant presbyopia or cataract, lens‑based options may be more appropriate than SMILE LASIK. These can include laser cataract surgery and implantation of multifocal or other advanced intraocular lenses.

Risks, side effects, and realistic expectations
All eye surgeries carry risks, and SMILE LASIK is no exception. Possible issues after SMILE or other laser vision correction can include:

1. Dry eye symptoms
2. Glare, halos, or starbursts, especially at night
3. Under‑correction or over‑correction, sometimes requiring enhancement
4. Infection or inflammation
5. Fluctuating vision during the healing period
6. Rarely, more serious complications affecting vision

For presbyopia and cataract surgeries, potential side effects and complications can include glare, halos, infection, inflammation, lens decentration, or the need for additional correction or lens exchange. Careful preoperative counseling is essential so that patients understand both the potential benefits and the limitations.

The clinic’s detailed examinations, AVELLINO DNA testing, retina evaluation, and ISO‑certified processes are designed to reduce risks and identify unsuitable candidates. However, no system can guarantee perfect results or zero complications. It is important to have realistic expectations and to discuss all concerns with your ophthalmologist before deciding.

Frequently asked questions

Is SMILE LASIK painful
During SMILE LASIK, anesthetic eye drops are used, so most patients feel pressure rather than pain. After the procedure, some discomfort, tearing, or light sensitivity is common for a short time. Your doctor will provide instructions and medications to help manage this.

How long will I need to stay in Korea
Many international patients plan to stay about one to two weeks. This allows time for the initial consultation, surgery, and early follow‑up visits. The exact schedule should be discussed with the clinic in advance.

Can I have both eyes done on the same day
In many cases, both eyes are treated on the same day. Your surgeon will advise based on your eye condition and overall health.

What if I am not suitable for SMILE
If SMILE is not recommended, the doctors will discuss alternatives such as LASEK, phakic lens implantation, or lens‑based surgery, depending on your age, prescription, corneal condition, and visual goals.

Will I still need glasses after SMILE
Many patients significantly reduce their dependence on glasses or contact lenses after SMILE. However, some may still need thin glasses for certain tasks, such as night driving or fine work. As you age, presbyopia can also develop, and you may need reading glasses even if your distance vision is good.

How do I prepare before flying to Seoul
Stop wearing soft contact lenses for at least several days before your examination, and longer for rigid lenses, according to the clinic’s guidance. Gather your medical history, previous eye exam records, and a list of medications. Plan your travel so that you are not overly jet‑lagged on the day of examination or surgery.

Soft call to action
If you are considering SMILE LASIK in the Gangnam area and want a clinic that offers SMILE pro, classic SMILE, and SILK in one place, this long‑standing ophthalmology clinic near Gangnam Station may be an option to explore. With multiple SMILE platforms, experienced ophthalmologists, and structured preoperative screening, the clinic aims to match each patient with a suitable procedure rather than a one‑size‑fits‑all approach.

Before making any decision, it is important to have a thorough eye examination and detailed consultation. You can start by using the clinic’s online consultation or suitability analysis system, share your basic information and travel plans, and then decide whether to schedule an in‑person visit in Seoul.
