20/250 before.. 20/15 and even can see some of the 20/10 letters. The most pain I felt was when I first walked outside after the procedure. All light HURT.. But once you get home, you sleep from the drugs for a few hours, wake up and you can see. I had 20/20 the very next day. It's been over a year and no problems, no dryness, pain, etc. I had it done at Revision off of polaris with a wavefront laser, it was around 3500.
