I am not an opthamologist, but here is my take:
The technology/techniques for this procedure are actually pretty good. The problem is a certian percentage of the population will have some scaring on the retina associated with the laser treatment. This may or may not have anything to do with the laser or the doctor, it is just an inherent quality in some people. Most physicians will do a pre-screen history and physical on you to make sure you don't have a tendenacy to scar, but even that is not fool proof.
You can limit the risks of the surgery, but never eliminate them.
Make sure the physician you go to is Board certified in Opthalmology, has a number of years of experience in the procedure, and has a medical licence that has never been revoked, suspended, etc. (You should be able to check all of these things on-line for free via your states Department of Professional Regulation.) Complication rate is somewhat patient dependent, so I would place less value on that statistic when looking for someone to do the procedure.
Good luck.
