I’ve been telling people that the reason they do one eye at a time is not merely because there is a slight but possible chance of complication to the surgery, but mainly because with one eye corrected, and one eye left alone, you have a chance to really compare, over days or weeks, the true difference in vision you are getting.
That alone would be worth doing, but you wouldn’t know it without being exposed to it in this manner.
I loved that comparison when I was seeing with one “good” eye. What was hard was trying to read. I got so I just read with the bad eye, and let the good one do what it wanted. Yep. It can be done!
