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.

There are basically 3 parts to LASIK:

• Creating the flap
• Laser correction
• Closing the flap

		Part I: Creating the flap 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 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.
