Thank you so much. This is a wonderful website. I'm sure I will have more questions as the months roll on. cac117
It's not as bad as it sounds.
1. Sometimes a cataract in a totally blind eye has to be removed because it "gets too ripe" (we call it a hypermature lens) and causes very high pressure, very much irritation and SEVERE pain. So if the ophthalmologist sees this is likely to happen say over the coming year removing the cataract to prevent the pain is ethical and good medical care.
2. Often when you do surgery on the first eye you learn something that will make the surgery on the second eye (your good eye) safer and easier. For instance how your eye reacts to anesthesia, surgery, sutures, medication, and post operative healing. What you learn on the first eye can make surgery on the second eye safer.
This is something I've done in the past.
