My left eye was roughly -2.5, and my right eye -5.0. I had a checkup the next day, and my vision was 20/15 (left eye perfect, right slightly blurry). Everything was hunky dory, and then suddenly, double vision! I was completely fine at night (still 20/15), went to bed, woke up, left eye is now hazy/blurry. It took me 2 days to see some far off text to realize I was getting double vision.
To make things a bit more complicated, I have map-dot-fingerprint dystrophy (my epithelial cells are weak), but I have never had any kind of pain/trauma/troubles before or after the surgery. The only oddity is the sudden double vision. My opthamologist spent a good 20 minutes just investigating, and brought in a second doctor, but neither see any obvious problems.
Anyone have something similar happen to them?
