Risks for both contact lenses and LASIK are incredibly low, but with that said strictly from a quantitative perspective, contact lenses carry a higher risk of permanent vision loss than LASIK. The issue is that the risk of LASIK is almost entirely front-loaded whereas the risk from contact lenses causing an infection that results in significant to total loss of vision accumulates little by little.

Including daily disposable contact lenses?

does it actually accumulate (memory), or is it a Poisson process where if you go a day with good luck, you start fresh for the next and every day, same unaccumulated risk?
