They tell you up front that the lasik surgery cannot overcome the natural aging process of the eye. You may need a correction down the road.
My wife had lasik about three years ago. By the way, it cost a lot more back then. She had extremely poor vision to start with. 20-600? Is there such a number? Anyway, the operation went great. Got her back to 20-20. After about two years she was starting to get blurry again so she got a pair of light glasses. She had major coke bottles before the surgery. Just in the last few months her vision has gotten a little worse. She went back for a consultation this week. They have to make sure there is enough tissue to do a correction. The results came back OK. She is going in for the correction next week.
