Did you know that for several years U.S Air Force pilots and NASA astronauts have been able to have Lasik and quickly return to flight duty. Previously they were restricted from flight duty if they had Lasik. This was due to the uncertainty of the safety and vision provided by this surgery. The US armed Forces and NASA have done extensive research on pilots in extreme conditions. Due to their research, every branch of the military allows aviators to have customized blade free Lasik.
