I had Lasik on both eyes in 2005. Before that I had ~6 diopter short-sightedness in both eyes, with slight astigmatism. The difference is magical and 5 years later it still amazes me. At a check-up one year later I had 20/20 vision, and haven't noticed any degradation since then. I never particularly noticed the halo effect at night. I did have very dry eyes for a year or so, but nothing that artificial tears couldn't fix.
That's not to say the procedure is without risks; but it worked out very well for me.
The reason for the dry eyes, I was told, is that the cut in the cornea kills some nerves, reducing sensitivity, so you don't _know_ your eyes are dry (and hence don't blink enough) until they are _really_ dry. The nerves eventually grow back.
I stare at computer screens for 12+ hours a day, and I do get dry and irritated eyes -- but I think that has more to do with the staring at computer screens, and not blinking enough, than the Lasik.
I had my operation done in Colombia, a country with strong expertise in Lasik (the microkeratome, the instrument used to cut a flap in the cornea, was developed in Colombia). At my one-year-post-op checkup (in New Zealand) the doctor recognized the name of my Colombian surgeon from journal articles. At the time the operation cost US$1000 (for both eyes), less than 20% of what it would have cost back home, and probably better quality.
