I had it done about 9 years ago. The process itself was quick and painless, with just a day or so recovery and I ended up with better than 20-20 vision. However, even though my eyesight had 'settled' beforehand (the prescription hadn't changed for 18 months), it started changing soon after the op and I started wearing glass for driving etc after about two years. It was nothing to do with the surgery itself, but if your eyesight is going to get worse, having laser eye surgery won't stop that, it only fixes the eyesight you have. I do find the glare worse now than before. Driving at dawn and dusk in particular are a pain! They have a 7 year guarantee, so would have redone it again for me for free, but I chose not to have it done. Having glasses doesn't bother me the same way it did when I was younger and the process is different the second time around (scarring etc makes it not quite as straightforward) and eyesight is not something I wanted to mess with iykwim! I'm still glad I had it done and would definitely recommend it.
My mum had it done about 5 years ago after wearing glasses since she was a young girl. She couldn't recommend it more highly! She's 65 now and wears glasses for reading (which most people that age do!), but not all the time.
