I'm not a boxer but I had the eye surgery done. It's pretty quick and sort of painless. Although the 4-5 hours after is pretty bad. I'd say 80% of the time they give you 20/20 or better and 90% of the time you are legal to drive with 20/40. I was only like -2.75 (don't know what that is as far as 20/?) but now am 20/15 and 20/20. HOWEVER, you must not take any hits around the eye for a while after the surgery. I believe for 1 month you can't really do anything slightly dangerous even like basketball and my doctor said 6 months before he would recommend full contact fighting. Ask your doctor though. Oh, and mine was $2800 for both eyes, but that includes "lifetime touchup" so basically I'll never need anything other than reading glasses again when I get old.....definitely worth it.
