LASIK eye surgery
in South Korea

A thin flap, a short recovery

LASIK eye surgery in South Korea, as at Sky Eye Clinic in Seoul, corrects myopia, astigmatism and hyperopia by lifting a thin corneal flap, reshaping the tissue beneath with a laser, and laying the flap back down.

Because the surface cells stay protected under the flap, recovery is short. At Sky Eye Clinic it is performed with the Amaris Red SPT laser and Co-Wave customization.

Procedure

How LASIK eye surgery works

LASIK means laser in-situ keratomileusis. It is performed worldwide and is known for stable, predictable results. Numbing drops are the only anesthesia.

Make the flap

A microkeratome creates a flap about 160 micrometers thick on the upper cornea. It shields the epithelial cells and Bowman's membrane.

Fold it aside

The flap is turned back to expose the corneal stroma.

Apply the laser

The laser reshapes the stroma to correct your refractive error.

Lay it back

The flap returns to its original position.

Who It Suits

Who LASIK is for

Typical candidates

  • You are 18 or older.
  • A doctor has judged you suitable after a comprehensive examination.
  • Your prescription has not changed over the past year.
  • Glasses or contact lenses cause you discomfort or side effects.
  • Your work or appearance makes glasses or lenses hard to wear.
Caution

When LASIK is not the answer

If that applies to you, read LASEK and New SMILE LASIK.

Trade-offs

What you gain, what to weigh

In its favor

  • Recovery is short, so working people can often return quickly.
  • The risk of corneal haze and myopia coming back is very low.
  • Numbing drops protect the epithelial cells and keep pain low.
  • No steroid drops are used afterwards, so steroid-related glaucoma or cataract is very unlikely.
  • Re-treatment or extra correction is straightforward if needed.

Against it

  • It demands an experienced surgeon with a delicate technique.
  • Flap-related complications can occur, which do not occur in LASEK.
  • Dry eye may last longer than after LASEK.
  • A thin cornea may rule it out.

Laser Options

Amaris Red SPT and Co-Wave

Amaris Red SPT LASIK

The Amaris Red laser fires at 1050Hz and ablates in under 1.3 seconds per diopter. It tracks the eye in 7 dimensions, measures corneal thickness in real time and uses a 0.54mm spot. Smart Pulse Technology (SPT) smooths the treated surface to support recovery and visual quality.

Co-Wave LASIK

A wavefront exam finds high-order aberrations, and the treatment smooths the corneal surface accordingly. Your data travels to the operating room on a personal memory chip. The clinic says it suits high myopia with astigmatism, presbyopia correction over 40, asymmetric corneal topography and high-order aberrations.

A cornea thinned by surgery can be strengthened with corneal cross-linking. Lasers are listed on the equipment page.

Fees are listed under LASIK cost in Korea. For international patients, the clinic lists fees at 49% off the regular rate, the same fee Korean patients pay, and adds a free MRI precision exam (worth KRW 100,000) and free autologous serum eye drops (worth KRW 200,000).

FAQ

Common questions

How thick is the flap?

About 160 micrometers. A microkeratome makes it on the upper cornea, and it is repositioned after the laser.

Am I a candidate?

Adults 18 or older with a prescription stable for a year, approved by a doctor after a full exam. It helps most if glasses or lenses are a struggle for you.

Does it hurt?

Numbing drops are used. On the day you may feel irritation, tearing and grittiness, which usually lasts about half a day after LASIK.

What if my cornea is thin?

Below a certain thickness, a LASEK-type surgery that keeps the most residual cornea is recommended instead.
