Get to someone who does cataract surgery. It is the simplest thing in
the world - in the right hands. I had cataracts in both eyes and about six
or seven years ago had them removed. When they remove them these days they
replace them with a plastic lens fit to your eyes. I haven't seen better
in fifty years (no glasses - except for reading) since the replacement.
They do them one eye at a time so in case there's a problem they don't blind
