I had Lasik done about 4 years ago. My vision to this day is better than 20/20, and I cannot express how great it is to not be tied to contacts or glasses. I had fuzzy vision for a few days after the procedure, but even through the fuzz I could tell my eyes were focusing as if I was using corrective lenses.
Now, the drawback was I did have problems with "lens flare" during the night for months after. Lens flare, for those who don't know, is the effect cameras display when pointed at a bright light in high contrast situations (like a street lamp at night.) You get that "star" effect. However, the sharp focus without any aid was enough for me to dismiss this, and I no longer have that problem.
The other problem that I do have to this day is regarding dryness. My eyes constantly feel like they are dry. However, I did have this problem prior to Lasik as I was horrible with contacts and didn't use them properly (I'd keep them in WAY past their prime, sleep in them overnight when I wasn't supposed to, and other stupid things like that.) I think Lasik probably made this issue worse, because I don't remember them feeling this dry. But as I said, I blame myself more than Lasik for the dryness.
Even with the dryness, I would do it again though. There's a lot to be said for being able to wake up in the morning with perfect vision, or taking a shower and being able to grab the conditioner instead of the liquid soap, or swimming and being able to actually see, etc. etc. My understanding is the procedure they use these days is even more simplified than what I went through, which more than likely reduces the possibility that you'd get dry eyes or a lens flare problem, or other side-effects.
