I had it done in June and it's the best decision I've ever made. My prescription was about -2.5 and it was getting to the point I had to wear my glasses all the time rather than just when driving/watching TV. I hated it.
I had it done at Optical express and it cost £1250. The process itself was pretty vile - not painful, just very unpleasant and claustrophobic - but very quick. Both eyes were done within ten minutes. Afterwards it was like a really, really strong chopping onions type feeling, my eyes ran loads and I just wanted to keep them closed. I came home and went to bed and felt OK when I woke up a few hours later. The following night I went to see a comedian and could see fine - without glasses for the first time in years! - but they felt dry and scratchy for about a week.
You have to sleep in goggles (which they provide you with) for a week and apply 3 different types of drops 4 times a day for a week - and then that's it! My eyes were quite dry when I woke up for a few months afterwards but I avoided using drops as if you use them too much your eyes stop producing moisture of their own and you become reliant on them - and now I'm doing great!
If you have any questions feel free to ask, seriously I've been recommending this to like everyone I know! There's also an affiliate scheme so I could give you a voucher for money off and I'd get some money for referring you if you decide to go for it.
