LASIK
Definition:
Laser Assisted In-Situ Keratomileusis (LASIK) is a refractive surgery procedure that uses the excimer laser to correct refractive error. The excimer laser is applied to the cornea under a thin flap of corneal tissue to decrease or eliminate the need for glasses or contact lenses.
How Does LASIK Work?
LASIK surgery works by sculpting the cornea in a precise manner to correct refractive error. By changing the corneal shape light becomes focused on the retina allowing clear vision. LASIK is the most commonly performed refractive surgical procedure today, with more than two million procedures performed worldwide each year.
During LASIK surgery a very thin flap is created on the front of the cornea. The flap is then folded back and the laser is applied to the underlying corneal tissue in a precise manner to correct nearsightedness, farsightedness and/or astigmatism. The flap is then replaced to protect the reshaped cornea underneath.
