During my trip (detail in that other thread), I did notice that I had less of fine motor movement, so that could cause unintended eye injury consequences and from what I know about lasik it does take time to heal, so I wouldn’t plan a trip 2 weeks or so after the procedure for that reason alone. You want it to heal right. But also realize that there is very little modern medical research on it for obvious reasons. So it’s a bit of a wildcard in the respect you ask.
