"That's not bad for perfect vision going froward as my family has a macular degeneration history. I will need to ask, as this will factor into the decision. It it will prevent macular degeneration, it will be well worth the cost"
It will not prevent macular degeneration and I doubt the eye doctor or anyone here suggested it might. Macular degeneration is a deterioration of the retina, in the back of the eye where the light is translated into electrical impulses that go to the brain. Think of it as the film in the back of your camera.
A cataract is like having built up dirt on the lens of the camera (if the lens were inside the camera not on the exterior). The exterior of your eye, the cornea is just supposed to be a clear tissue through which light passes before being focused by the lens. A bit oversimplified but...
Now no matter how wonderful your lens and focus may be, if the film in the back of your camera doesn't work, you get no picture. Be sure your eye doctor is aware of your family history, (s)he may have some suggestions to reduce your risk.
