What Lasik is like
I had pretty bad myopia and a tiny bit of astigmatism. Wore soft contacts for many years, and then had IntraLasik surgery. With the newer technologies, the Lasik surgery can correct eyes much better than with contacts or glasses. In my case, the astigmatism was so slight that it didn't warrant a prescription for it. So my contact lenses were only for the myopia. But the Lasik surgery now includes Wavefront technology - it's basically a machine that maps your eye to a very minute degree so the actual laser can correct all tiny imperfections, even things smaller than glasses/contacts can address. So my surgery corrected my astigmatism as well as my myopia.
Surgery was very quick, no pain at all, everything done by lasers with no tools of any sort touching my eye, so no real chance of infection. The eye heals itself surprisingly quickly. You will be amazed at how fast you can see normally. There wasn't any pain, but it was "squicky" feeling, watching that laser and seeing a piece of my cornea peeled back. I can't describe what it's like - it doesn't hurt, but it is a strange thing to *watch* and know what they are doing to you.
They gave me a pill (muscle relaxant) that I had to take about an hour before surgery, then had me sit in a darkened room laid out in a recliner watching a movie while they got everything ready. Just as I was about to fall asleep in the recliner, they took me back for the actual surgery. At some point they put some drops in my eye that numbed it completely. I laid there and had to focus on a dot while the laser did the cutting (peels back a slice of the cornea - then a separate laser resurfaces the lens). I believe they held/strapped you down so you couldn't involuntarily move during the procedure. They also will put tiny clamps on your eyelids so you don't blink. The laser "tracks" your normal eye movement and works away. It has some kind of safety shutoff feature if your eye were to move too much. The actual procedure took about 5 minutes.
After it's over, they give you an Ambien and have you go home and rest. At about 2 hours or so after the surgery, the eye drops wear off, and there can be pain for a brief time (1/2 hour or hour?). With the Ambien (plus having had the muscle relaxer earlier in the day), you sleep through this period and never feel a thing. Wake up from the nap, and your eye feels fine. You will have clear plastic shields to put over your eyes to sleep so you don't rub your eyes while you sleep.
Biggest side effect is dry eye, but I had no trouble with that. They will have you use artificial tears (eye drops) for a week or two after the surgery, but after that, you are fine. I went back to work the next day, no trouble.
The most important thing is to find a good surgeon who has done this surgery a kajillion times before.
Edit - My night vision is much better now than it was with contacts. Day vision of course is better too. My eyes are less dry now than they were with contacts. (I used to have trouble with contacts falling out due to drying out.) I got the Lasik because I couldn't see a damn thing swimming without contacts, and I hated always having to wear goggles or be blind.
