LASIK
LASIK is a surgical procedure intended to reduce a person's
dependency on glasses
or contact lenses. The goal of this Web site is to provide objective
information to the
public about LASIK surgery.
LASIK stands for Laser-Assisted In Situ Keratomileusis and is a
procedure that
permanently changes the shape of the cornea, the clear covering of the
front of
the eye, using an excimer laser. A knife, called a microkeratome, is
used to cut
a flap in the cornea. A hinge is left at one end of this flap. The
flap is folded back
revealing the stroma, the middlesection of the cornea. Pulses from a
computer-
controlled laser vaporize a portion of the stroma and the flap is
replaced. There
are other techniques and many new terms related to LASIK that you may
hear
about.
