Hi Ken,
Cataract operations have gotten better.
I had a plastic shield that I used at night. I was very careful for
the two to three weeks I would it.
I obtained a Snellen charge - and verified my distant vision at in the
20/25 to 20/20 range.
I also checked my refractive status.
After eight weeks, with everything OK - I had the other eye done.
But be sure to find a GOOD ophthalmologist to do it. Check with the
experience of others who have had it done from THAT MD.
Good luck!
