Make no mistake -- Lasik is surgery, and anyone who implies otherwise is not forthcoming.
The surgeon creates a flap in the cornea, and a laser is used to reshape the underlying cornea. The surgery takes less than half an hour, and patients feel pressure, but no pain.
However, that does not mean it is a simple procedure that just anyone can perform. Like any surgery, the experience of the surgeon is the most important factor in achieving the best results.
