Is there a maxiumum refraction diopoter prior to PRK? If there is is this waiverable to? My vision is -7.25 which I think is disqualifying for pilot but what about NFO? Also is there a max refraction requirement to become an officer in any field even though its correctable to 20/20? My second choice would be SWO and dont know if that has vision restrictions like pilot or NFO. Thanks.
