I at one point was talking to the son of an optometrist about this, and his mother had one argument that convinced me I wouldn't try it if I needed glasses. She claims that all of the people presenting papers at optometry conferences still wear glasses. If they're not convinced, I'm not convinced.

Is an optometrist really going to advise you to have a procedure which could me you will never buy a pair of glasses from him again?
