ASL, thanks. That clears up the eyeglass problem. I don't mind one or the other, but the idea of bifocals bothers me.

In the laser clinics here, "Lasik," "PRK" and "wave front" procedures are offered by the three surgical eye clinics here. What are the differences, if any? (Lasik and PRK may be for different purposes, both are offered by the same clinics).
