Lasik
LASIK is a surgical procedure intended to
reduce a person's dependency on glasses or contact lenses. 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. |
