I had it 10 years ago when I was 30 years old. Serious it was the best thing I've ever done and would highly recommend it. Think it was Lasik with "wavefront recognition" or something - basically went for the best one at the time because, well, it's your vision isn't it.
It's like a miracle when you've had to wear glasses. In and out within an hour and can see without glasses, though you have to take it easy for a couple of weeks while your eyeballs heal.
Don't be fooled by any "lifetime guarantee" though, they make you go to so many super-inconvenient follow up appointments (even years after you've had the treatment done) that invariably you will stop going to them and at that moment the guarantee is no longer valid. They also basically close down and reopen the day after under a different name to end all the warranties if people actually start trying to take them up on them.
I don't know if I'd be brave enough to have it done again, my eyesight seems a tiny bit worse 10 years later but I still don't need glasses.
