Smart SMILE LASIK | Gangnam Central Eye Clinic

A More Advanced
Femtosecond Laser
5th-Generation Smart SMILE LASIK
Smart SMILE LASIK, upgraded one step beyond SMILE LASIK
  • Gangnam Central Eye Clinic avoids so-called “assembly-line vision correction.”
    For our patients’ safety, we perform only a set number of surgeries per day.
Gangnam Central Eye Clinic
shows you what Smart SMILE LASIK can do!
  • Gangnam Central Eye Clinic’s
    Smart SMILE LASIK
  • Low Energy Smart LASIK
    This vision correction procedure uses the ATOS device to create, within the corneal stroma and sized to the required correction, a thin piece of corneal tissue called a lenticule; the lenticule is then removed through a small 2 mm incision at the edge of the cornea.
    After surgery, many patients return to daily activities soon after, and we aim to reduce the risk of side effects such as dry eye and corneal ectasia; recovery varies from person to person.
Recovery in just 4 hours,
safety UP!
side effects DOWN!

Gangnam Central Eye Clinic × SCHWIND ATOS, Germany

Gangnam Central Eye Clinic’s ATOS
is a vision correction system
that supports careful, precise surgery.

  • Precise Eye-Movement Tracking
    (EYE TRACKING SYSTEM)
  • Curved Interface
    (Patient Interface)
  • Smooth Lenticule Edge Finish
    (Transition Zone)
  • More Accurate Astigmatism Correction
  • 2 mm minimal incision
  • Low pulse energy of 75 nJ
  • 01. SMART LASIK
    4 MHz
    laser repetition rate
  • Smart SMILE LASIK uses a laser repetition rate of 4 MHz, which aims to shorten surgery time and limit thermal effects on the cornea.
  • 02. SMART LASIK
    Reduced glare
    versus 4th-generation procedures
    (The difference is in the edge)
  • Smart SMILE LASIK cuts the lenticule’s edge in an arched shape, a design intended to reduce glare, and is planned to help preserve residual corneal tissue.
  • 03. SMART LASIK
    Cyclotorsion compensation
    & 7D eye tracking
  • ATOS, with a 7D eye-tracking function, compensates for subtle tremors and movements of the eye during surgery, helping the procedure stay on its planned position.
  • 04. SMART LASIK
    Careful,
    precise astigmatism correction
  • The astigmatic axis measured while seated during testing often differs from the axis when lying down for surgery. Correcting for this phenomenon is essential for patients with astigmatism.

    Gangnam Central Eye Clinic’s Low Energy Smart LASIK
    integrates the ATOS device with the SIRIUS 3D corneal topography system, enabling even more precise astigmatism correction.

Smart Corneal Strengthening (CXL)
SMART Corneal Collagen Cross-Linking
  • SMART CXL
    What is corneal strengthening?
  • SMART Corneal Collagen Cross-Linking
    Corneal strengthening (CXL) at Gangnam Central Eye Clinic is performed during vision correction surgery such as Smart LASIK or LASEK. Riboflavin (vitamin B2) is used to increase cross-linking between the collagen fibers of the cornea, reinforcing weakened corneal tissue. It has been performed in more than 100,000 cases across 55 countries, including in Europe.
    • Minimize likelihood of myopic regression
    • Minimize the
      likelihood of keratoconus or corneal ectasia
    • Suitable for
      high myopia and high astigmatism
    • Surgery possible for thin corneas
    • Revision after LASIK or LASEK possible
    • Strengthens corneal tissue
  • SMART CXL
    Corneal Strengthening
    Procedure Steps
    • STEP 01
      After excimer laser ablation, riboflavin is applied to the cornea.
    • STEP 02
      Ultraviolet light is applied to the cornea.
    • STEP 03
      The procedure is completed.
Autologous Serum Eye Drops (PRP)
Platelet-Rich Plasma
  • PRP
    What are autologous serum eye drops?
  • Platelet-Rich Plasma
    When our body is injured, healing growth factors that treat and protect the wound are released; PRP eye drops are prepared by separating and extracting plasma and platelets rich in these growth factors from the blood.
    • Dry eye prevention
      Nutritional support to the epithelium from autologous serum can help prevent dry eye.
    • Faster visual recovery
      Epithelial regeneration factors in the serum aid rapid wound healing and recovery.
    • Side-effect prevention
      Immune components and healing effects of autologous serum can help prevent side effects.
    • Pain relief
      Modulatory growth factors and anti-inflammatory action in autologous serum help relieve pain.
  • PRP

FAQ

Smart SMILE LASIK Frequently Asked Questions

Does Smart SMILE LASIK make a corneal flap?

No. It removes the lenticule created in the corneal stroma through a small side incision at the edge of the cornea, so there is no step of lifting a flap.

Which surgery is better?

We do not say that one is better. Corneal thickness and shape, prescription, and intraocular space differ from person to person, so the same method may suit some and not others. We choose within the limits allowed by your test results.

Why are the tests divided into five parts?

Because each has a different purpose. Vision testing sets a baseline, glare and halo testing looks at night-time symptoms, corneal testing shows which methods are possible, tear film testing sets the treatment order, and retinal testing checks the overall health of the eye. The method cannot be chosen from one category alone.

Is Smart SMILE LASIK available to everyone without conditions?

No. We check corneal thickness and shape, prescription, and the tear film and retina to judge feasibility. If the tests show you are not suitable, we suggest other options or advise against surgery. We cannot tell you if it is possible without test results.

How are LASIK and LASEK different?

They differ in how the corneal surface is handled. LASEK removes the epithelium and then reshapes the stroma; LASIK creates and lifts a corneal flap, performs correction, and lays it back. Recovery speed, pain, and the thickness margin differ accordingly.

Can I have just the tests?

Yes. Testing is not a step toward surgery; it determines which methods are possible and whether now is the right time. Depending on the results, we may not recommend surgery.

Is Smart SMILE LASIK possible for high myopia or high astigmatism?

The higher the prescription, the more tissue must be removed, so residual corneal thickness becomes the key. We decide based on the value measured in testing.

If my cornea is thin, can’t I have surgery?

Procedures that reshape the cornea may not be possible. In that case, we consider placing a lens inside the eye without reshaping the cornea. However, lens implantation also requires the corneal endothelial cell count and anterior chamber depth to meet safety criteria.

I heard my cornea is thin—should I still get tested?

It’s better to be tested. Hearing that it’s thin alone does not tell us which methods are ruled out. We need to look together at residual corneal thickness, anterior and posterior corneal shape, and elasticity to make a judgment.

How long does recovery take with Smart SMILE LASIK?

You can resume daily activities from the next day, and the eyes may take about 1 week to 1 month to stabilize. Recovery speed varies by individual.

Are there options other than surgery?

Dream Lens is an option. It is a special contact lens worn during sleep that flattens the central cornea overnight to reduce refractive power.

What if the tests reveal another eye condition?

Treatment for that comes first. The retinal exam is not only for deciding on vision correction but also for checking the overall health of the eye, and any findings take priority over vision correction.

When is the method decided?

We decide during consultation after reviewing the detailed test results. We do not choose a procedure before evaluating your eyes.

Are these the same tests as for revision surgery?

The five parts are the same, but the purpose differs. Revision-surgery testing focuses on finding the cause of reduced vision.

Can I get Smart SMILE LASIK even if I have dry eye?

We first check the tear film. If dryness is significant, we treat it first and may reschedule the surgery.

My eyes feel dry—can I have surgery right away?

If tears are insufficient, we treat the tear film first. Severe dryness can cause fluctuating vision and fluctuating measurements. After the tear film stabilizes, we remeasure and decide on the method.

In the SMILE LASIK testing, why do you measure pupil size?

We measure how your pupil size changes with light, including individual variation, because it is linked to glare and halos at night.

What is the Authenticity Card?

It is a card issued to patients who have Smart SMILE LASIK with the SCHWIND ATOS device from Germany, so you can confirm which device was used for your surgery.

My myopia is still progressing—can I have it now?

If you are in a growth phase and myopia is progressing, we consider Dream Lens first. While your prescription is changing, we do not perform corneal refractive surgery to correct it. We confirm stability by remeasuring at set intervals.
