With regards to vision, I would not recommend getting surgery on your own, for AFROTC cadets anyway. If you are selected for pilot training out of AFROTC and require corrective surgery, the Air Force will provide it. This may also be true for the USAFA and OTS, but I'm not sure.
However, as will all surgeries, there are risks, and one risk of any surgery on the eye is blindness, both permanent and temporary, so weigh the risks and rewards before going through with it.
Good point, I forgot to mention that.
