[Kipper is King]

Researching to get a good surgeon and find a place with very up to date equipment is critical. Any surgeon will probably tell you that they have the latest and greatest equipment, but a little Internet research can't hurt. Yes, it will cost a lot more for an experienced surgeon with new equipment, but you don't want to gamble with your sight.

I had severe complications after having PRK surgery done years ago. Almost needed a double cornea transplant at age 21.

Fortunately, the complication I suffered from, "corneal haze," went away after a few years. I still need glasses.

Everyone may get mild corneal haze that lasts a little while after laser eye surgery. Hence the halo effect.
Severe corneal haze like mine is almost unheard of today, but do your homework on the surgeon/equipment to make sure you are limiting the risk.
