Good question. LASIK is disqualifying for most cool military jobs including pilots, divers, and special operations. LASIK involves slicing the cornea to nearly remove it, but when it is re-attached it never quite heals up, it just "sticks" to the eyeball...This creates two problems:

1) A blast overpressure (nearby explosion or slipstream from ejection) is liley to remove the cornea, since it is no longer really firmly attached. This would be bad.

2) Divers, pilots, and parachutists who experience large pressure changes may be subject to nitrogen bubbles forming between the cornea and eyeball...a unique manifestation of common decompression sickness (the bends). This is bad too.
