They calculated in 1/2000 lifetime chance of vision loss from contacts vs a 1/10000 chance for refractive surgery.
I can't read the full article, so this might be incorrect. The summary seems to indicate that they're only considering vision loss, but most of the reports that I've heard of about lasik problems aren't vision loss as such, but the introduction of artifacts.
