I had it done about 4 years ago, best decision ever.
For me it worked immediately, I slept for about an hour when I got home after the procedure and when I woke up I could see perfectly. I probably used eye drops for dry eyes for about 6 months to a year, now it is so rare that I end up buying a new bottle when it happens.
The only side effect that I don't like is that I get a halo around lights at night. It isn't bad normally, the only issue is during rain storms driving. Occasionally all the rain drops will get a halo depending on the street lights and it is distracting.
