While I'm not sold on the Oculus, I do see an market opening for an FDA-approved VR headset with FDA-approved software. Some time ago, I read reading an article about a study where they had strabismus sufferers play Tetris while wearing a specially designed helmet. IIRC, the results were promising, but I'm sure there's room for other games.

The cost of an equivalent VR package could come in under the the average cost of LASIK ($2,118 USD), however, given the failure potential of LASIK, I would be willing to pay a premium for the former.

UPDATE: Okay, so clearly, I haven't been keeping up with the industry, as such a system is currently in trial, Diplopia. Apparently, FDA approval is only required if a product/service is claiming to diagnose a condition, however, this company is still trying to shoot for it.
