I had mine done about nine years ago - one eye at a time. At my consultation, I was told I had a 75% chance of not having to wear glasses again. When I questioned this further, i was told there was a 25% chance I'd need glasses for driving. Happy with this, I went ahead with the treatment. It wasn't painful but I did need to keep a tube of lacrilube handy, to apply at night. If I forgot, I found that my eyelids would stick to my eyes in the morning - causing pain when I opened them. Please don't let this put you off - it's sounds worse than it is and the dry eyes do go. For many years, i had better than 20/20 vision. However, a couple of years ago my eyesight started to deteriorate and have done ever since. I am disappointed as I thought the results after treatment would be permanent but, after asking questions, it would appear that any deterioration your eyes would have suffered will still happen after laser surgery. Having said all this, If my eyesight stabilises again, I would definitely undergo the procedure for a second time. I have yet to meet someone, like me, who has needed glasses again after such a long time - I guess I'm just unlucky. :o( Good luck.
