Thought I'd chime in because of all the glowing reviews here about LASIK.
For me well over a year after surgery I now know it has turned out to be the worst decision I ever made.
My vision in low light is worse with very aggravating aberrations known as starbursts/halos/glare. These are caused by higher order aberrations and cannot be corrected by glasses or soft contacts. I'm trying scleral lenses soon.
LASIK generally increases the higher order aberrations of the eye by inducing irregular astigmatism, which reduces visual quality. LASIK patients may lose contrast sensitivity and see starbursts, glare, halos and multiple images.

My very near vision is also gone. I used to be able to see clearly all the way in till about 3-4 inches from my face, now I have to pull something 10-12 inches away to see it clearly.
My red dot sight, if turned up to be somewhat bright, now starbursts too.
You're looking at more like a 20%+ chance of these sorts of problems, really 100% if you have large enough pupils.
If you only read one article about LASIK before deciding to undergo it, read this one:
Some patients who undergo the eye surgery report a variety of side effects. They may persist for years, studies show.

Look into being fitted for scleral lenses if you have higher order aberration issues (ask your optometrist). Keratoconus is one natural cause of these issues and I think a poster above talked about keratoconus/scleral lenses, LASIK is a man-made cause of them. Also as people age I think these issues crop up more. If you go this route you need to find an optometrist with a lot of experience fitting these. Look for one with the Eaglet Eye Surface Profiler and an Optical coherence tomography (OCT) scan machine.
Look into OrthoK if you have regular nearsightedness/milder astigmatism. These are rigid lenses you leave in only overnight that temporarily reshape your corneas during the day to correct your vision. Non-surgical, you can return them if you don't like them. Unlike LASIK where if it screws up your vision it's for life.
