Different Laser Correction
Procedures
LASIK
– This is a surgical technique in
which the excimer laser is used under the surface of the cornea.
The surface cells are saved by hinging them to one side.
The excimer laser then reshapes the underlying corneal tissue.
The surface cells are then returned to their original position. This procedure is used to treat nearsightedness,
farsightedness, and astigmatism. In
general, LASIK is associated with more rapid visual recovery and is
relatively comfortable. Typically,
both eyes are done on the same day.
PRK
– This is a laser procedure used to treat
nearsightedness, farsightedness, and astigmatism. This procedure is done completely on the surface of the
cornea and requires no incisions. The
surgeon starts by removing a surface layer of cells called the epithelium
(these cells naturally regenerate themselves every few days). The excimer laser, preprogrammed by the computer, is then
gently applied to the surface of the cornea to reshape the surface
curvature to the proper
refraction. This procedure is
virtually painless and takes under ten minutes.
The initial layer of cells removed is so thin that the structural
integrity of the cornea is maintained throughout and recovery is speedy.
