What is LASIK?

LASIK is short for "laser-assisted in-situ keratomileusis". It is a simple procedure that uses laser to reshape the cornea in order to change the focal point of the eye.

How does LASIK work?

There are basically 3 parts to LASIK:

  • Creating the flap
  • Laser correction
  • Closing the flap

Part I: Creating the flap

step 1 of LASIK surgery to create the flap on the epithelial surface

A microkeratome or laser (Intralase) is used to create a "flap" on the outer corneal tissue. The "flap" can be folded away to expose the central part of the cornea to be reshaped.

Part II: Laser correction

Excimer laser is used to reshape the cornea.

Part III: Closing the flap

Step 3 of LASIK Surgery to close the flap after laser eye treatment

The "flap" is replaced over the reshaped cornea and the eye is allowed to heal on its own.

For myopic patients, LASIK removes a thin layer of the central cornea. The central cornea is flattened and the eye is able to see far objects better.

For hypermaetropic patients, LASIK creates a circular ditch in the periphery cornea. The central cornea becomes more curved and the eye is able to see near objects better.
