I know people who have had this surgery including umpires. There are no guarantees. One guy can see better during the day, but has problems under the lights.
Others have had complete success while one individual swears it helped only a little inspite of what the doctor says.
Personally, I have an astigmatism and this is the first year I have worn glasses full time. While I was expecting a fair amount of ribbing on and off the field from players and coaches, not one word was said to me the entire year by a player, coach or fan.
Guess they figured I was just as bad with them as without so any comments would be a waste of time
