Thanks for pulling out the data! One problem is that "somewhat", "very", "completely" don't give a good picture of how dissatisfied these 2.7% of patients are. It's possible some of them developed serious dry eye which can be totally debilitating.
This doesn't mean the procedure shouldn't have been approved, it most likely means that folks need to do better patient education and qualification. Not everyone needs to be a good candidate.
It's also possible that these results vary a lot between LASIK docs. I'd expect that some qualify patients more thoroughly than others. Risk for developing side effects can be assessed beforehand, to some extent.
