At 22, I don't think it'll be too bad. They definitely advise that your prescription should be pretty stable, and mine had been for years.

I don't know about you, but I found it helped to watch the operations being done. I'm not sure what your doctor does, but at mine's office, in the back where the surgery rooms are, they have 19" TVs inside the surgery rooms that people can watch on the outside, broadcasting the procedure. I must have seen 30 of those.

The thing that amazed me the most is the turnover rate at which they do this. The average operation lasts about 10 minutes. It's like a fast food restaurant Would you like fries with your cornea?
