My dads a eye surgeon in sydney,
he refuses to do corrective lasik, he claims that it was rushed out and the is no historical data on the procedure, he wears glasses as does most of the dr.'s he works with,
saying that he says that he doesn't do it because wearing glasses is not a bother for him, he reckons that if it is so important for you not to wear glasses (want to be a pilot, soldier, that sort of thing) then go for it, the real risk is that when your 70 + your eye sight will deteriorate faster then others, and the fact that you will need reading glasses by the time your 50. its safe, for the short term can drive pretty much the next day.
Hope that helps!!
