I had the procedure done almost 10 years ago and it has been a pretty positive experience for me. The biggest negative impact has been dry eyes similar to what lockem mentioned. I can't go without eye drops (just generic Visine) in the morning. Also - my night vision has suffered. Be sure to check whether or not you would suffer from these "halos". In low light, bright points of light appear to have a fuzzy halo around them. I really hate driving at night now due to that.
Other than that, it was a good choice for me. The coolest thing was that the doctor purposely over-corrected my vision, so for the first several months I could see clearly at a ridiculous range. In a few months everything normalized and I still have better than 20/20 vision at this point.
One last thing - invest in a nice pair of shades before the procedure if you decide to go through with it.
