Hi there. 35 year old male, had Lasik done about 4 years ago. Should have done it sooner!
I was near-sighted and wore glasses/contacts all my life. It wasn't until my vision normalized (stopped getting worse) that I went in to see (pardon the pun) the options for corrective surgery.
In the 4 years since I've had mine done I'm sure its even better now. Hell, when I was getting my eyes done new equipment was coming out every six months that was twice as good as the previous!
Anyway, it's a simple procedure. You can take a light sedative if you're nervous and the whole process is about 10 minutes long. They numb your eyes (obviously) and have you look directly at a red dot. The "worst" part is cutting the cornea flap open. Then there's some brief popping -- about 15-20 seconds worth -- and the flap is put back over. Repeat with second eye.
Your vision will be pretty blurry when you get out. Within a few minutes to an hour it will be noticeably better. Overnight you'll be near perfect the next day. Very important to not rub/touch your eyes for several days! You'll be putting in sterile eye drops every 15 minutes and slowing down to a couple times a day.
Within 2 days your vision normalizes. A repeat "touchup procedure" may be required. You'll have multiple follow-up checkups to see how your vision is doing. Mine was 20/15 since day one and is still 20/15 today!
Only downside is my night vision (which was excellent) isn't quite as good. It's called the "halo effect" and has nothing to do with iPods.

Lights at night will have kind of a halo/blur around them. It's not terrible but worth mentioning.
In closing, best thing I ever did. The freedom is amazing. Waking up in the morning and being able to see, perfectly, takes some getting used to. Wearing normal sunglasses, seeing while swimming, etc, are all new experiences. I should have done it years earlier!
Lasik is a no-brainer. Take out a loan or whatever. The change in your quality of life can not be overstated.
