I feel your issue... I have had similar issues...
-Cataract surgery on both eyes, 4 years ago
.... followed up the cataract surgery with lasix to correct astigmatism...
--All was well with the world... 20/20 in both eyes..
2 years later, I developed a detached vitreous in the right eye.. That required a Vitrectomy to correct. During the surgery, the surgeon found 9 small tears of the right retina, and repaired them with laser.
My right eye remained at 20/40, after the detached vitreous/retina repairs.
Now, a Macular Pucker has developed where the retina tears wear repaired. The result is a slight double vision issue that greatly affects my ability to focus on a pool ball sharply... just really hard to get right. I also have some issues while driving, especially at night, due to the blurry/double vision.
I can close one eye and everything is pretty sharp, but you need both to be right to play well.
I can still play pool, but I have confidence issues, due to the vision problems.
I am 72 years old... the eye doctors do not want to repair the macular pucker, which would require another vitrectomy... they say 20/20 left & 20/40 right is best left alone, but the double vision real sux...
