I did Lasik in 1997, when I was riding raunchy horses and got tired of sweat running into contacts or glasses getting dislodged when I needed to have both hands. I corrected to 20/15 in one eye, and the other eye optimized to a viewing distance of 3 feet (it's nice to bee able to see your food). It was great. No side effects at all. (I.E., rings aroung light point sources, dry-eye syndrom, etc.).

Now, 8 years on, I'm back to about 20/100. There is a 10 year 'warranty', but I don't know about doing it again, even though it would be free. I'm 48, and I think the odds of a good outcome decrease with age.
