What's the worst that could happen?
I had a family member who had it done at the beginning of this year.
The first eye went off without a hitch - seeing 20/20 within days of the surgery.
The second eye is where she ran into "complications" - an infection that lead to temporary blindness in the eye.
After several painful visits over a couple of months, she slowly regained her sight in the eye. Now, about 7 months after the surgery, it's back to normal - other than the occasional "floater" that sometimes blurs her vision.
She got lucky because the doctor told her that the infection should have lead to permanent damage and loss of vision.
There are a lot of things that can go wrong with the surgery and the recovery. I'm sure you can find quite a few horror stories online.
However, everyone I spoke with that had it done said it was well worth it - including the family member.
