A little late posting this. A few years ago I had it done. I will stop short of calling it a miracle, but I now see 20/20 from both eyes. I had it done twice on my right eye. The first time around it was 20/15, shortly after that I got a detached/torn retina(hereditary, not a result of the Lasik). After the retina surgery I was nearsighted again in that eye, after about a year I was able to have the Lasik redone, now 20/20. You will suffer mildly for a few days, and it took me about a year to get used to seeing things differently.
Now the drawbacks. My eyes are a little dryer than before. Lights have a weird halo or glare that I am completely used to now. This also lessens as the scar tissue in your eye heals. I am a jeweler and noticed that things up close were harder to focus on and now require magnification. By up close I mean 2-3 inches from my nose, this doesn't effect normal up close things like reading or removing a splinter.
I would recommend getting several opinions about the surgery, form optometrists, opthomalogists or other eye surgeons who do not perform Lasik, before getting the surgery done.
Oh, yeah one more thing, you can smell your eyeball burning under the laser.
