Imagine waking up in the morning and not having to reach for your glasses. Wouldn't it be nice to be free of the morning and evening ritual of taking contact lenses in and out? Wouldn't it be terrific if you could participate in sporting activities with out having to worry about the burden of wearing glasses or possibly losing a contact lens?
Laser vision correction surgery involves techniques that correct or reduce nearsightedness, farsightedness, and astigmatism. To correct nearsightedness, the curvature of the cornea is flattened. For the farsightedness, the curvature of the cornea is increased. Techniques that reduce astigmatism reshape the cornea producing a more evenly curved surface. Currently we use two procedures with the excimer laser, they are LASIK and PRK. The excimer laser is so precise that each pulse can remove 39 millionths of an inch of tissue in 12 billionths of a second. It would take 200 excimer laser pulses to cut through a human strand of hair.

After viewing the illustrations of the procedures, you may be asking yourself "what, other than the flap is the difference between the two procedures?" The PRK procedure tends to have a little more discomfort than the LASIK procedure. PRK takes a bit longer for the vision to improve. Remember that during PRK we actually removed the outer layer of the cornea. It takes some time for this layer to heal itself. LASIK on the other hand is usually painless and a vision outcome is usually rapid.
