I had it done just under a year ago. Because my prescription was high, I had a bit of regression (I went back to being slightly short-sighted) so I had it redone in January. Since then I've had no problems. I still need to use comfort drops as my eyes are a bit dry, but this is apparently a normal reaction as the eyes can take several months to settle down. For me it's a very small price to pay, to go from being completely dependent on specs/contact lenses to not having to wear them at all. I would have no hesitation at all in recommending anybody to go for it.
As Exquisite Touch rightly says, it is painless to have done. A bit uncomfortable, but certainly not painful. And yes, definitely do your research. Go for a consultation, research it on the internet, get recommendations from people who've had it done. Find out as much as you can about it so you know exactly what's happening and why.
But yes, definitely go for it, you will not regret it.
