Well, I'm not a doctor, but I had LASIK 2 years ago and it was the best thing I've ever done. My vision was about 20/550 and now I'm 20/20 in one eye and 20/15 in the other.
They give you a Valium and it calms you down, I guess. Not sure, since I just sort of gritted my teeth and got it over with.
So first they clamp your eyelid up with what I think was like a big eyelash curler or something, but it basically fits into your eye socket. Was uncomfortable but not bad. They numb your eye with some drops. You don't feel anything in the eye itself. I was very nervous about looking at the red laser dot they tell you to look at...because if you move, you can screw up the procedure. But it was only 30 seconds or so and you just remember to breathe out and you can keep your eyeball still for 30 seconds. Your other eye has a patch or something on it. Then they take out the clamp and do the same thing with the other eye. Then you sit up and lo and behold, you can read the clock across the room.
That afternoon, though, was awful....light was excruciating and I just lay in the car like a ball on the way home. They give you sleeping pills and you sleep that day or night or whatever. I got up around 9 pm for a snack, felt awful and went back to sleep. YOu get this mask thing you have to wear while sleeping for a few days so you don't rub your eyes. You have to take these eye drops for about 3 days and then eye-wetting drops for as long as your eyes feel dry.
The next day, I felt great and at my checkup, had 20/35 or something. The day after, I was driving and by a week after the procedure, was at 20/20 and 20/15. My eyes are still dry in the mornings now, but a small price to pay. My doctor told me that I wouldn't have been able to wear contacts much longer because they were causing dry spots on my eyes..so it was LASIK or glasses.
Am so glad I did it. DH did it too, as did SIL and BIL and all of us are thrilled with the results. I do know one guy who had something go wrong with his, and he had to wear a special contact lens for 2 months to correct it, but now he's 20/20 in both eyes. Good luck.
