I had it done about 7 years ago, and it was the best thing I've ever done for myself.
I had really bad eyesight, hated glasses, and contacts were so inconvenient.
It took a few days to meet w/ an eye specialist, who ran a whole bunch of tests. The actual surgery was done at night, so that I'd go home right away to sleep.
It didnt hurt. They used a few drops to anesthetize my eyes. I just felt a bit of pressure.
They covered my eyes in pirate-like patches and sent me home to sleep. By the time i got home, the anesthesia had worn off, so my eyes hurt a little (not too bad) and were quite watery. I still couldnt see anything, though.
The next morning, i went back to the doc, who removed the eye patches.
And I could see again! It was an amazing feeling.
If you're considering it, definitely see a specialist who can tell you more about it and get it done! It's so worth it.
