What is LASIK?
LASIK is short for “laser-assisted in-situ keratomileusis” and is the most common type of laser vision correction. It involves creating a hinged, partial thickness corneal flap, using a microkeratome blade or a laser, and then gently lifting the flap to expose the underlying corneal tissue. An excimer laser is then used to reshape the underlying corneal tissue. The flap is laid back down to act as a natural bandage and the eye is allowed to heal on its own. LASIK is used to correct near-sightedness, far-sightedness, and astigmatism.
