Thank you for the additional information.
There are some instances that the cataract is bad enough that the doctor cannot look through it. If that was the case with you, then it could have been difficult to see any retina problems. The most common retina problem is macular degeneration.
The Fuchs' is something the doctor would have know before the surgery. Fuchs' causes swelling of the cornea (front part of the eye). If the swelling is bad enough, there is a surgery available to help with that (full or partial corneal transplant).
If the retina problem is bad though, then the cornea surgery many not improve the vision too much.
So, you should ask your doctor about how much the Fuchs' contributes to the vision loss and how much the retina problems contributes.
Currently, wet macular degeneration is treated with injections into the eye and dry macular degeneration is treated with high dose vitamins.
