I know of people who have had cataract surgery, some no longer needing to where glasses at all, while others now use reading glasses only. I for one are due to see an Ophthalmologist in February to discuss the issue. As I am still fairly active, walking, fishing, road cycling, I will probably opt to have my lens replaced for distance as I have always been short sighted,opting to wear reading glasses after that if required. Visual astronomy no longer interests me so that is not a issue.
