I ran into a lot of the complications this article mentions (halos, dry eyes, and for a few weeks afterwords a blurriness from cells dying called something like "superficial protein keratitis"). All of them were temporary though and cleared up after a few weeks/months. (Well, except the halos, but they're not that severe and I already had bad night vision and halos before this, it just made them a little more pronounced) I do think it's a procedure you should really think carefully about before you do it, but I wouldn't want the FDA to ban it or something. Overall I'm currently happy with it.

My suggestion would be, if you're thinking of doing it, make sure the eye doctor who checks out your candidacy is one you trust and hopefully have been with for a while. When it comes down to it, the procedure itself is pretty safe and automated so the part to optimize is screening people before the procedure happens.
