My wife had the Lasik surgery, and she wore bifocals for a number of years. Due to her prescription, she still wears the cheapo reading glasses you get at the drug store. From what her doctor said, it's not uncommon that the Lasik will occasionally correct some problems if not 100% of them. She's very pleased that she had it done. I elect to continue wearing my glasses.
Quick story: The morning after the surgery, everyone that had had the surgery (about 10 people) the previous day had to return to the doctor's office for a quick checkup. We arrive at the parking lot about the same time everyone else does. All of those who had the surgery were wearing the large wrap-around sunglasses that they were given after the surgery. We were in the elevator going up and I told my wife I felt like I was at a Men In Black reunion with all the dark glasses around us, lol.
Oh, this particular doctor had it setup where family could sit outside the surgery room (glass walls) and view the surgery on a tv monitor mounted in the waiting room (and you could see your family member through the glass wall also). I watched the first "cut" of them laying back one of my wife's pupils and then I left and helped myself to some of the very good free coffee they had in the other waiting room. Surgery only takes 10 minutes.
