I had cataract surgery in 2014 two weeks apart. I got an artificial lens in each eye to replace those clouded by the cataracts. Everything went well.
For the first eye I had a plastic shield taped over my eye area until the next morning. I went back to the eye doctor for it to be removed, then my vision was checked. It was 20 over "some very large number" before surgery. After it was 20/15 and perfectly clear. There were still some "problems".
The cataracts had clouded my vision so I wasn't getting the normal amount of light into my eye. After the surgery, everything was very bright and painful, but I had been provided with dark glasses to avoid the brightness and pain problem.
Everything close was blurred, but I bought some cheap reading glasses as soon as I could to solve that problem.
I had problems at home bumping into things. I soon realized that the amount of light inside didn't make things clear enough for my brain to decide which eye to use. My "old" eye was still cloudy and dim, plus everything was blurred in it. My solution was to make sure all the lights were always on. That seemed to convince my brain to use information from the "new" eye and to ignore everything from the "old" eye.
Finally, my cataracts had a yellow tint, so my brain had adjusted to make the yellow tint seem normal. After the surgery everything had a blue tint.
The surgery on the second eye was the same as the first. After the second eye was fixed, all the problems caused by having two "different" eyes went away. It took about two months for everything adjust to the new "normal", except I still had to use reading glasses for close vision.
