If you are a career pilot type and can pass the medical for the type of flying you do (or want to do), I would be VERY wary of laser surgery just as a lifestyle convenience thing.
I know one airline pilot who had it (LASIK I think) whose cornea ended up so scarred that he couldn't get a medical. The docs told him he needed cornea transplants but the company health plan declined to pay for it (since his vision wasn't so bad that he couldn't work at jiffy-lube or starbucks). The guy ended up as a sim instructor until the company got tired of paying him CA pay (contract sim guys make $30-40K) and fired him.
There is a definite, if small, risk. Personally I would do it in order to qualify for say a military pilot slot, but not just to avoid wearing glasses. Actually I'll probably get it done after I retire from flying.
