Getting Lasik for me wouldn't really help me. Due to some retinal scarring, I have lost my central vision in my left eye, so if I were to get rid of my glasses my vision would still not be perfect.
I'm not interested in Lasik at this point. My eyesight isn't terrible (just not optimal) and I like the way I look with glasses. A friend of mine had to get Lasik for her job. She hated the experience, but loved the results.
Glasses can be very sexy. Lisa looks amazing in hers, as does a certain female cylon (GOD DAMN YOU, ANDREW, FOR MAKING ME WATCH THAT). I've often considered getting myself a non-prescription set of glasses to wear simply as jewelry. The right glasses give the illusion of a slimmer face and squarer jaw.

Fake glasses are the ultimate Emo accessory. I certainly get why people would like the look of glasses. It also seems arbitrary to wear one type of ornament, but not another (penis hats anyone?). However, the Emo stigma puts me off of the concept a bit.
It wouldn't be so bad for me, but at the age of 17, I'm considered legally blind by my eye-care specialist, with a vision of 20/2000 (yes, 2000) in both eyes, with astigmatism in both. (I actually think that it's worse than that, but when I asked, they told me that it's not really measured past that.) I think that it's somewhere around -6 or so. I have no idea, seems like I remember seeing that on the paper.
Anyway, I've also had to have surgery on my right eye. They had to straighten out my retina because it had gotten pulled on the edges, and I'd have gone blind in less than six months in that eye. I was told I will always see random floaters (black/white dots, somewhat large in size, that obstruct my vision mildly) in it, and that someday I will eventually develop a cataract in the eye because of the surgery. I also can't see colors as vibrantly in it as I used to be able to.
On top of all that, I can't get contacts, because the eye doctor told me my corneas were too large for the contacts he knew of, and they couldn't stay on my eye and would just slide down it.
So, I'm slowly losing color and focus in my right eye. The prescription in it is 20/2200 now as opposed to my left which is 20/2000. I don't know if it's going to get worse, but it feels like it is. I mean, I've even got this weird problem where if I look at something with a bright light, like an LED, with only my right eye, the LED moves independent of the object it's on? It's really weird, and it kind of scares me. I'd like to have two functioning eyes in the future.

I've noticed this too, but only if the rest of the room is really dark.

I've noticed the same thing many times too. I also have perfect vision. I don't think it is a problem with your eye, more likely something to do with image processing in your brain.

The reason is really quite simple and in itself should not be a sign of disease (but ask your eye doctor): refractive materials (like the eye lens or the lenses of your glasses) diffract light differently depending on the light's wavelength, i.e. its color. Shorter wavelenghts (violet and blue light) is diffracted more strongly than longer wavelengths (red light). This is why prisms split the white light of the sun in its spectral components. In optical systems like camera lenses the effect is called chromatic abberation, it produces the colored fringes of white objects, in particular in the corners of the pictures.
The weird movement of LED light relative to the physical object is particularly noticable because LEDs emit light that is often quite pure in color, that is, made up of only a small range of wavelengths. A source of white light (= a mixture of many colors) only gets somewhat blurry and colored edges from chromatic abberation, because all the different colors move to a different extent, but the pure LED light moves visibly "out of the box". Because of the stronger diffraction of blue light, the effect should be biggest with this color. Also, the effect should be bigger in the peripheral vision, when you don't look straight at an object - just as cameras produce colored fringes in the corners of the picture. Most people will not notice that, because we see with lower "definition" there. But if you wear glasses and, while wearing it normally, look at the LED through the outer zones of the lens, the shifting becomes very obvious.

Wow, okay, you nailed it. Thanks. That's pretty cool.
One thing though, I didn't know it was supposed to be a constant thing, I thought it was just a temporary effect. When I look at something and have it move like we're talking about, it stays put instead of centering itself on the source when I stop moving. Is this normal?

I don't know if I understand you correctly here, but there should indeed be no automatic re-centering of the light. As long as all the optical parts (your eye, your glasses etc.) have the same position and orientation, the shift of the light relative to the object should also be the same. Take the prism: it doesn't stop diffracting when you stop moving it.

Wow, I've been thinking about this all wrong. Thanks a lot! Now I just have the color loss and focus loss to worry about. :P
Coming back to the thread's topic: while Lasik sounds very tempting, I'd still like to have more long-term studies on it, preferably on people getting old with laser-treated eyes. The Lasik method weakens your cornea, and I'd like to know it will still hold up when I get older. Also, I'd need a much higher probability that I will no longer need glasses after the operation. There is absolutely no point for me in getting Lasik done only to need less strong lenses. "Weak glasses" and "no glasses" are completely different games.
Is anyone turned off by Lasik simply based on the procedure itself? I have a major dislike of objects touching or getting too close to my eyes (one reason I do not wear contacts). The idea of being awake, aware, and able to see while my eyes are operated on seems like a nightmare.

They asked me if I wanted to be awake when I had retinal surgery. Fuck that.
Vhdblood, as far as I know, regular insurance doesn't cover LASIK or the like in the US, since it is considered a cosmetic procedure. You can do a FSA to avoid the taxes (if you work at a company that supports it). Depending on your salary, that can add up to almost $2k for a $4k surgery. A couple folks at work did that (contribute the X amount in the year, have the surgery on one eye on 12/31, then on 1/1 or 1/2, deposit the X amount into their FSA and have the surgery done on the other eye).
Some companies will also work out discounts for their employees with some of the major LASIK companies, however, it's still not cheap. The one I looked at (TLC) was around $2000 an eye. They did Tiger Woods' eyes, although I imagine the celebrities get better followup treatment than the rest of us peons...

Take THAT, emo kids!
This is the friend test: Who likes Close to Me?
