To pick up on one aspect of the answer provided by kp2001:
If you want to be a naval aviator, you had best not submit to LASIK without the specific blessing of the Navy, or you will find yourself disqualified.
A few years ago, the Admissions Dept and Senior Medical Officer announced that they were more inclined to grant waivers than to having young men and women undergo corrective surgery. They also instituted a waiver program that offered Navy sponsored PRK to prospective aviators if such were needed for them to qualify for aviation.
Not sure of the extent to which NAVY continues to subscribe to this position, but I surely would not doing anything with your eyes without getting a current, authoritative statement in advance.
