IIRC the chance of complications for Lasik is about 10x that of the one for intraocular lens implantation. The nature of the complications for the latter is also more along the lines of "an eye infection for a month" instead of something permanent.
I definitely suggest researching it (and not mentally lumping it in with Lasik, because they are quite different). Cheesy, but my only regret is not having done it years sooner.
