| How LASIK Corrects
Your Vision |
|
Laser-in-situ Keratomileusis (LASIK)
is a procedure used to reshape the cornea using a laser. This allows
the cornea to better focus light on the retina so refractive errors
are reduced or eliminated. The Excimer laser that is used for LASIK
uses a cool light beam to remove corneal tissue from the inner cornea.
The beam of the laser is so accurate that it can cut notches in
a single strand of human hair. |
 An instrument called a microkeratome is used to separate the surface layers of the cornea and create a corneal flap. This flap stays attached to the rest of the cornea on one side. |
 The laser delivers pulses of ultraviolet light onto the inner cornea. Each pulse removes a microscopic layer of the inner cornea to reshape
the surface of the cornea. |
 The
corneal flap is put back into place where it bonds without the need
for stitches. |
