To reduce a persons dependency on glasses or contact lenses one can have Lasik surgery. The term LASIK stands for Laser-Assisted In Situ Keratomileusis and is a procedure through which you permanently changes the shape of the cornea. The cornea is the clear covering of the front of the eye.
Doctors use an excimer laser to perform this kind of surgery. A small 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 middle section of the cornea. The pulses from a computer controlled laser vaporize a portion of the stroma and the flap is replaced. Other techniques are also in use.
