Had mine done April 2001 right after I turned 33. My eyes (prescriptions) changed constantly since 5th grade. Contacts or glasses. I had to have the Bausch+Lomb machine for my lasik 13+ years ago due to astigmatism and while more expensive than the standard Lasik, it's still the best money I've ever spent on myself. Still see great - no glasses needed (yet), but my phone is starting to get a little harder to read close up.
