I've spoken with friends who've gotten that done like 20yrs or so ago, and they told me their vision has degraded back down again not exactly as bad as before, but kinda like it was when they originally elected to do it. What did your Doc say in regards to how long the benefits would last? I'm asking on the chance that the technology is perhaps a little better now?
When I had it done in '06 my prescription hadn't changed in the previous 12 years. My Dr's opinion was that because of that there was a good chance I wouldn't need glasses again, except for readers (which pretty much we'll all need some day). He didn't make any guarantees though so time will tell.
