One way to correct for short sight is by flattening the cornea (i.e
reducing the curvature of the cornea). I understand that this can be
done by a laser beam controled by a computer. ARE THERE ANY SIDE EFFECTS
TO THIS METHOD? HOW LONG IT TAKES BEFORE FULL RECOVERY? WHAT IS THE USUAL
COST OF THIS OPERATION AND WHERE IT CAN BE DONE?.
THANKS.

The laser procedure to which you refer is called Photorefractive Keratectomy (PRK). This procedure is still classified as "investigational" in the United States. Although it has been performed in other countries for some time, it has not yet received FDA approval for general use. Because of this, I cannot tell you specifically where the procedure can be obtained or how much it might cost.
With regard to side effects, there are potentially several. They vary from overcorrection and under-correction to corneal opacification. Although the risks of this procedure are currently felt to be relatively low, some of the more recent investigational data with regard to PRK is less favorable than this author had originally hoped.
