Laser Eye Correction
(Refractive Eye Surgery)
LASIK is the
most common refractive eye surgery. You might choose LASIK if you're
nearsighted or farsighted, with or without astigmatism. LASIK is performed
using a laser programmed to remove a defined amount of tissue from your
cornea. With each pulse of the laser beam, a tiny amount of corneal tissue
is removed. The laser allows your eye surgeon to flatten the curve of your
cornea or make it steeper.
During the LASIK procedure,
your eye surgeon uses a special blade or special cutting laser to cut a
hinged flap about the size of a contact lens away from the front of your
eye. Folding back the flap allows your doctor to access the tissue in your
cornea that needs reshaping. Using a laser, your eye surgeon then targets
specific parts of your cornea. The flap is then folded back into place and
usually heals on its own without stitches.
