I had LASIK done about 4 yrs ago and I couldn't be happier. Yeah, I get a sligh halo at times when my eyes get really dry or really tired (usually after benders), but it has not seemed to affect any films I've ever looked at, CT, MRI, or plain. Granted I'm still a student, but I've spent some time in the reading room and I've tried to pay attention to any distortion I might have. The other issue is that I had this done long ago, and I might have been a bit naive to think I wouldn't have problems, but if I had to choose to do it NOW, I might do A LOT of research to find the best place to get it done, even if it was across the country.
