I got LASIK last December, so I am at just over 10 months right now. It is one of the best things I have ever done.
I didn't go in blindly (no pun intended), I looked at the horror stories and the bad experiences and knew very well what could go wrong and how wrong it could go. The biggest factor seemed to be experience. I found a doctor that has performed over 6,500 procedures. By the time you reach that point you pretty much have seen everything.
I also had the right eyes for it. You want eyes that don't over dialate as well as you don't have too much of a correction factor that might thin the cornea too much. I was right in the middle of everything, which made me feel personally comfortable.
To some of the other comments we are approaching 25 years of Laser eye surgery. I don't really think long term effects are "unknown" in the sense that suddenly after 20 years of having the surgery your eyes pop out. The biggest issue that has been noted is that the eyes age normally which causes you to eventually need reading glasses. Other long term things that done seem to go away is a reduction in night vision and a certain degree of starring and glare at night.
I had starring and glare at night, but it improved until about the 3 month mark and then leveled off. Now only one I am seriously tired does it effect my vision to the point where I even notice it. I ran into similiar issues when I wore contacts.
Another common issue is dry eyes. I probablly have slightly more dry eyes then before, but my doctor got me on a regiment of restatis right after the surgery which help conteract the effect. Right now I don't take any drops, but do carry around a bottle of artificial tears in my attache just in case but haven't used them in 3 months or so.
My advice is that it isn't for everyone, but investigate it and see if you are a good candidate, because it was the best thing I ever did for myself!
