someone told me that scuba diving is dangerous for people who have undergone lasik surgery due to the pressure change possibly decompressing bubbles formed at the site of the graft. Can anyone qualify these claims? I only learned of this when I was talking to a friend of mine about the space program... the US Navy accepts candidates for fighter pilots who have undergone lasik, but the National Aeronautical and Space Administration (according to my source) won't allow lasik patients who are otherwise qualified to enter the space program as astronauts. When I asked possible reasons why, my friend told me his idea about the bubbles. There's no telling who he heard this idea from. So, who has the straight dope?
