PRK was what resulted in halos and starbursts. Early LASIK didn't have a large enough flap cut so in extreme darkness a pupil could dilate out past the corrected area. I don't think they cut as often now and instead use ablative procedures that remove material from the surface after first mapping the eye's surface. After the surgery you could have some dryness that can take some time to go away, use drops.
If you're prescription is stable I HIGHLY recommend the procedure. I went from 20:70 20:90 to 20:20 20:30 - I was legally blind without correction and my Dr laughed when I asked that. I got the surgery the January following the initial FDA approval in the United States. I was no longer able to wear contacts as my eyes had begun to starve for oxygen and the blind spots that glasses have nearly got me killed in traffic - literally. I went from losing my towel on the beach and not being able to read the alarm in the morning to being able to read an alarm across the bedroom - I could read that distant alarm 2 hours after surgery. I was terrified prior to the surgery, a near miss driving with glasses solved that damn quick.
When my surgery was done procedures were cruder, the FDA limited what they could do (to my detriment), and they didn't know about the pupil dilation yet. I wouldn't trade it back for the world! The difference this made in my life has been incredible. I've suffered no side effects other than some dryness which can cause Chelazians in my eye lids if I'm not careful. My vision remains pretty good, I'll need reading glasses before too long I suspect. I could have a tune up done to sharpen things but considering what I lived with before I'm not sweating it. My night vision remains good but age has taken its toll in that dept, I don't mind as it beats being blind.
I should admit, I've run into one or two people with horror stories and I'd never do mono vision unless I never had stereo vision to begin with (I know someone like that). The number of success stories I've encountered is far far higher. It's still surgery, not to be taken lightly, but its a damned miracle for some of us...
