LASIK · LASEK and 2Day LASEK

LASIK corrects vision under a protective corneal flap; LASEK works on the surface, suiting thin corneas and very high myopia. GS Eye Center's 2Day LASEK replaces the alcohol-and-brush step with an all-laser process on the SCHWIND Amaris Red 1050s, reducing the wound area by about 40% so pain eases from day two.

The basics

What actually differs between LASIK and LASEK?

Both use an excimer laser to correct the corneal stroma. The difference is how the laser gets there.

ProcedureHow it reaches the stromaCharacter
LASIKCreates a corneal flap, lifts it, corrects underneath, closes the flapFast visual recovery; the flap must be protected. GS performs the flap by laser, never blade - see VISU LASIK
LASEKRemoves the thin epithelial surface layer, then corrects the exposed stromaNo flap at all - the cornea keeps maximum structural strength; the epithelium regrows over a few days
The GS method

What is 2Day LASEK?

Conventional LASEK loosens the epithelium with alcohol and strips it with a brush. 2Day LASEK does the entire process with the laser - more precise, a smaller wound, and a name taken from its goal: pain easing from the second day.

Step 01Laser removes the epithelium

The surface layer is prepared by laser - no alcohol, no brush.

Step 02Laser corrects the stroma

The Amaris Red reshapes the corneal stroma to your prescription.

Step 03Protective lens placed

A therapeutic contact lens covers the eye while the surface heals.

40%Less wound area than conventional LASEK

Day 2Pain begins easing two days after surgery
Day 4Follow-up progress exam

A smaller ablation area means less nerve disruption, so pain is reduced and the quality of vision is better protected. Because there is no corneal flap, flap-related complications - corneal wrinkles, tears or gas bubbles - do not arise, and the eye is more resilient to external impact. If the exam confirms your eyes are suitable, surgery can proceed the same day - a schedule that also works over a weekend.

SCHWIND Amaris Red 1050s excimer laser system
Equipment

SCHWIND Amaris Red 1050s

The German excimer platform behind 2Day LASEK, tuned for surface ablation with less collateral stress:

  • 1050Hz repetition rate - a short laser time that reduces heat damage, corneal drying and haze risk.
  • 7-dimension eye tracking - anticipates involuntary eye movements during the procedure.
  • SmartPulse - shapes each pulse to the cornea's geometry for a smoother ablation surface, supporting faster recovery and less glare and pain.
  • Less tissue removed - the platform ablates less corneal tissue than conventional LASEK for the same correction.
Candidates

Who tends to choose the LASEK track?

Thin corneas

Surface-first approach

With no flap consuming corneal thickness, LASEK remains open to corneas too thin for flap-based surgery.

Very high myopia

Ultra-high prescriptions

Extreme myopia that rules out other laser methods can still qualify for the surface track.

Sport & impact

Active lifestyles

No flap means nothing to dislodge - a fit for contact sports and physically demanding work.

Night vision

Glare-sensitive patients

The smoother ablation surface is aimed at reducing night glare and halo complaints, with low regression tendency.

FAQ

LASIK · LASEK questions

Both correct the corneal stroma with an excimer laser. LASIK creates a protective flap and recovers vision faster; LASEK removes the surface epithelium instead, preserving more structural strength - the usual pick for thin corneas, very high myopia and impact-heavy lifestyles. The 50-plus-item pre-operative exam decides which your eyes support.

Conventional LASEK soaks the epithelium in alcohol and strips it with a brush. 2Day LASEK performs the entire process by laser - more precise, with less pain and faster recovery.

If your eye condition qualifies, yes: exam, consultation, doctor's review and surgery can run in one visit, with some waiting between steps. This is the schedule most short-stay visitors use.

The epithelium needs to regrow, so plan on two days or more before routine activities feel comfortable - with pain typically easing from day two and a progress exam around day four.
