I had it done in 1997 after 40 years of coke bottle thick glasses, bad astigmatism, etc.
My vision is still 20/15 (or whatever it is when I see at 20 feet what others can only see at 15 feet).
The 'halo effect' went away after about 6 months. I have no night vision problems at all.
I would not hesitate to have it done again, or to pay for my kids to get it (their vision is more or less ok & my wife's is perfect).
The only drawback is that I get 'dry eyes' when I'm tired, probably because my eyes still aren't used to seeing all they time (I used to take my glasses off and not see anything but a blurr further than about 2 feet away).
As I age, my near vision is deteriorating so I may need reading glassess in 5 or 10 years and I need a maginfier to see really small print. But that's life - I wouldn't hesitate to do it again (though now it costs 1/4 what I paid).
Waking up the next day after the proceedure was almost a religious experience: "I can see!" /forums/images/graemlins/smile.gif
