Didn't you know that having your eyes lasered automatically leads to rejection? It's sad, but true...
That situation may change in the future, and to be fair it shouldn't be a problem in a closed cockpit aircraft without ejection seat...
[edit, as I'm home from work I and have time to explain]
Basically the procedure for Lasik and its contemporaries involves cutting a flap in the cornea, then using a laser to "remould" the tissue under the flap. The flap is then laid down in its original position. Now here's the catch...
...The flap of the cornea, strangely, is unable to heal itself, so will effectively remain attached by a small amount for the rest of the patients life. You can imagine the problems that this could cause if the eye was subjected to unexpected windblast etc (decompression, command ejection, birdstrike/windscreen failure)...
