I've had mine done about 4 years ago, when I was 21. It was to correct my severe near sightedness, which was a -6.5 on both eyes. Because it's my eyes I didn't want to take any risk so I looked around for the best doctor in the area. He charged more than other people but I didn't mind too much. Four years later and I still have 20/20 vision. Although some times I get really paranoid about my sight going bad so I had to check with other people, who also have 20/20. It was a relieve to know they can't see small letters across the room as well. I've had little to no problem with my experience. The eyes ached a little but I was fine after a week.
Bottom line: Best money I've ever spent.
