I would say that for about 4-6 weeks max. I would occasionally have very slight fluctuations in my vision. Was it always because of the surgery? I honestly couldn't say, but I'm sure it was a factor. At about that time or shortly before, it was apparent that one of my eyes was not as close to 20/20 as I would like, so when I flew, I would wear a contact lens on it.
After the surgery there is some cloudy vision, but that cleared up within about 24-36 hours. When flying at night I have no problem with either interior or exterior lighting. When I used to wear contacts, I could "see" the edges of my contacts, as it would tend to flare some lighting. That is not the case now. The clarity now is like the difference between wearing glasses to contacts. They don't compare.
