Why SMILE is the Top Choice
for Vision Correction in Korea

: Faster, Safer, and Flap-Free
SMILE LASIK in Korea
SMILE LASIK in Korea is widely recognized as a safe and advanced 3rd-generation laser eye surgery
that improves upon traditional LASIK by eliminating the need for a corneal flap.
Using a precise 2mm micro-incision, this flapless vision correction technique preserves
more of the cornea’s natural structure, which results in:

  • 1
    Faster recovery
  • 2
    Reduced dry eye risk
  • 3
    Greater corneal stability
  • 4
    No flap-related complications
With its strong safety profile and consistent outcomes,
Korea has become a leading destination for SMILE LASIK, supported by advanced ZEISS technology and experienced surgeons.

However, vision correction is not a one-size-fits-all solution.
The most suitable procedure depends on your corneal condition, vision needs, and lifestyle.
A comprehensive eye examination is essential to determine the best option for you.

What is SMILE LASIK?

: The Future of Laser Vision Correction
SMILE LASIK (Small Incision Lenticule Extraction) is a minimally invasive, 3rd-generation laser vision correction procedure performed through a precise 2mm micro-incision.
It differs from earlier vision correction procedures:

  • 체크 아이콘

    LASEK / PRK removes the corneal surface

  • 체크 아이콘

    LASIK creates a corneal flap

  • 체크 아이콘

    SMILE corrects vision without a flap, preserving the cornea


Using the ZEISS VisuMax 500 femtosecond laser, a small lens-shaped tissue (lenticule) is created inside the cornea and removed through the micro-incision to reshape the cornea and correct vision.
Because SMILE avoids flap creation and large surface removal, it offers:

  • 체크 아이콘

    Reduced dry eye risk

  • 체크 아이콘

    Greater corneal stability

  • 체크 아이콘

    Faster recovery

  • 체크 아이콘

    A more comfortable recovery



In short, SMILE LASIK corrects vision from within the cornea — delivering precise, flapless, and structurally stable results.

The Principle
and Process of
SMILE LASIK

SMILE LASIK corrects vision through a precise 2mm micro-incision in the cornea, reshaping the cornea from within while preserving the outer surface.
Unlike traditional vision correction procedures, it uses no-flap technology, allowing for faster recovery, reduced dry eye risk, and improved corneal stability.

How SMILE LASIK Works

: The 3rd Generation Evolution
SMILE is a 3rd-generation laser vision correction procedure that differs from earlier methods:

  • 체크 아이콘

    LASEK / PRK removes the corneal surface

  • 체크 아이콘

    LASIK creates a corneal flap

  • 체크 아이콘

    SMILE removes a small lenticule inside the cornea without creating a flap



A femtosecond laser creates a small lens-shaped piece of tissue called a lenticule within the cornea. This lenticule is then removed through a precise 2mm micro-incision to reshape the cornea and correct vision.

Comprehensive Pre-Operative Testing

SMILE LASIK is not a one-size-fits-all procedure. A thorough pre-op eye examination is essential to determine eligibility and ensure maximum safety.
At EYEPLUS, we conduct more than 50 advanced diagnostic tests, including:

  • - Vision & Refraction Testing: Measures myopia, astigmatism, and target correction level
  • - Corneal Thickness & Topography: Analyzes corneal thickness, curvature, and symmetry
  • - Corneal Tomography (3D Imaging): Screens for conditions such as keratoconus
  • - Fundus Examination & Intraocular Pressure Test: Checks for retinal conditions and glaucoma
  • - Pupil Size & Night Vision Analysis: Predicts glare and halo risks
  • - DNA Analysis (Avellino Dystrophy Test): Screens for genetic corneal disorders

This comprehensive safety screening system ensures that each patient receives a personalized and appropriate treatment plan.

The Step-by-Step Surgical Process

SMILE LASIK is performed under local anesthesia (eye drops) and typically takes about 10–15 minutes for both eyes.

Because the procedure uses a minimal incision and does not create a corneal flap, patients typically experience:

  • 체크 아이콘

    Rapid healing

  • 체크 아이콘

    Minimal discomfort

  • 체크 아이콘

    Quick return to daily activities

  • Step 1 Lenticule creation

    STEP 1. Lenticule Creation

    The ZEISS VisuMax 500 femtosecond laser creates a precise 3D lenticule inside the cornea.

  • Step 2 micro-incision

    STEP 2. Micro-Incision (2mm)

    A small, precise incision of approximately 2mm is made on the corneal surface.

  • Step 3 lenticule removal

    STEP 3. Lenticule Removal

    The surgeon gently separates and removes the lenticule through the incision, reshaping the cornea to improve vision.

3D Eye Fixation:
Maximum Safety
and Comfort

The ZEISS VisuMax 500 uses a proprietary 3D Eye Fixation system that stabilizes the eye with low intraocular pressure.
Unlike conventional laser systems, it conforms to the natural curvature of the cornea, reducing pressure on the eye and improving patient comfort throughout the procedure.
As a result:

No “blackout” during the procedure
Reduced intraocular pressure
A more stable and comfortable surgical experience

This system also helps minimize conjunctival bleeding and protects conjunctival goblet cells, preserving tear film stability and reducing the risk of post-operative dry eye.
By maintaining gentle and stable eye fixation, the system enhances both surgical safety and overall visual recovery.

Accurate Visual Axis
Centering for
Sharper Vision

Precise visual axis centration is essential for achieving high-quality vision, especially for clear night vision.
The ZEISS VisuMax 500 maintains low intraocular pressure, allowing patients to maintain visual awareness during surgery without experiencing a blackout. This enables accurate alignment based on the visual axis rather than the pupil center alone.
As a result:

  • 체크 아이콘

    More accurate and customized centration

  • 체크 아이콘

    Improved visual clarity and sharpness

  • 체크 아이콘

    Better night vision with reduced glare and halos

By aligning treatment with the patient’s true visual axis, SMILE LASIK provides more stable and precise visual outcomes.

Optimized Laser
Irradiation Tailored
to Your Corneal Shape

Each eye has a unique corneal curvature, pupil center, and visual axis.

Conventional laser systems often center treatment on the pupil, which may not fully reflect the patient’s true line of sight.

SMILE LASIK at EYEPLUS uses optimized laser irradiation aligned with each patient’s visual axis, creating a more accurate and customized laser profile.
This approach provides:

  • 체크 아이콘

    More precise alignment based on the visual axis

  • 체크 아이콘

    Improved visual clarity and stability

  • 체크 아이콘

    Better night vision quality

Micro-Precision
Incision Location and
Range Control

SMILE LASIK is performed through a precise 2mm micro-incision, designed to minimize tissue disruption and preserve corneal nerves.
The location of the incision is carefully determined based on the patient’s refractive error, while the extent of the incision is adjusted according to the degree of vision correction required.
This level of precise incision control allows for a more stable and personalized procedure.
As a result, patients benefit from:

  • 체크 아이콘

    Reduced nerve damage and improved tear stability

  • 체크 아이콘

    Faster recovery with minimal downtime

  • 체크 아이콘

    Safer and more controlled vision correction


By tailoring both the location and size of the incision, SMILE LASIK enhances surgical accuracy while preserving long-term corneal health.

SMILE LASIK vs.
Traditional LASIK

The key difference between SMILE and LASIK is whether a corneal flap is created.
Traditional LASIK requires a large corneal flap, while SMILE uses a precise 2mm micro-incision without creating a flap. This reduces disruption to corneal nerves and helps preserve the cornea’s natural strength.
As a result, SMILE offers:

  • 체크 아이콘

    Lower dry eye risk

  • 체크 아이콘

    No flap-related complications

  • 체크 아이콘

    Faster recovery

  • 체크 아이콘

    Greater corneal stability



Because of these advantages, SMILE LASIK is often preferred for patients with active lifestyles or those concerned about dry eye.
Comparison of LASIK flap and SMILE micro-incision. Comparison of LASIK flap and SMILE micro-incision.
Category SMILE LASIK LASIK
Surgical Method Laser applied within the cornea without creating a flap Corneal flap is created, laser applied to inner layer, then flap repositioned
Incision Size Approximately 2mm micro-incision Approximately 20mm corneal flap
Pain & Dryness Relatively low Varies by individual
Recovery Speed Faster recovery Moderate recovery
Ideal Candidates Patients with thinner corneas or those seeking faster recovery Patients with sufficient corneal thickness

Both SMILE LASIK and traditional LASIK allow most patients to return to daily activities the day after surgery.
However, SMILE LASIK generally offers greater freedom during early recovery, while LASIK may require a few days of caution until the corneal flap stabilizes.

Because SMILE LASIK uses a small 2mm micro-incision without creating a flap, patients generally experience greater freedom in daily activities during recovery. This can be particularly convenient for international patients with limited travel schedules.
