Consumer Reports, reported the results of some LASIK follow-up surveys in their August 2009 edition:

Survey finds 53% of laser eye surgery patients experience at least one side effect and 22% still have problems six months after surgery.
This is the kind of stuff causes me some hesitation. Consumer Reports is not perfect but they are also not a BS, alarmist outfit. There is a LOT of money being made on LASIK procedures, which after all take the doctors just minutes to do, so there's a big incentive to push the procedures and to cover up complications in the results.
