If you go for LASIK get a doctor that does a lot of them and has a track record for success. Avoid Billy-Bob's LASIK-taxidermy-septic pumping & stump removal. Who knew you could do LASIK using lasers from discarded CD players, a drill-press, and an industrial vacuum?

When LASIK goes well you can end up with near perfect eyesight without glare or aberration. When it goes bad you can end up with glare and star-patterns around lights that makes functioning at night almost impossible, constant eye irritation that feels like you always have something in your eye, and, worse case you lose sight altogether. Patch and parrot time. The more serious consequences are much rarer and failures come disproportionately from doctors who don't do many of this sort of operation.

Doctors who do this operation a lot, particularly when they are working with the same group of techs and nurses, have higher rates of success and better result overall.
