Had it done 4-5 years ago. Quick and painless, made me wonder why I hadn't done it earlier.
My main concern was developing myopia again after the surgery. Sure enough my eyesight today is poorer than it was immediately after the surgery and I expect it'll continue to get worse over time.
Here's how I found my surgeon: I asked the various doctors I interviewed who'd done their eye surgery. Surprisingly many of them had used the same person - he was generally regarded as the best by the other surgeons. Once I found that out I was willing to pay more and go with the best.
Overall I had an excellent experience, my only regret is not doing it sooner.
