I'm done with the cataract surgery, but might have to go back for a new lens in the left eye. Seems there is a flaw in the lens
. They will try a laser first, but if that fails; back to the little operating room.
If anyone here is a photographer, and has added a diopter to the viewfinder, chances are, it can be removed. I had diopters installed on all three Nikon cameras and when first using one after surgery, I forgot about them, and thought the AF system had gone haywire. Just a hint....
