Just celebrated proudly the centennial birthday of a family member on Sunday. His one cataract operated successfully 30 year ago and followed by other l0 year later, and acted as a 70 years now.
Cataract doesn't need rush to operation until it affects people routine daily living. Its progress is slow. The stage of each is possible different for some people. One by one is a smart decision. Some one can do most things without wearing their (new) eye glasses except driving in high speed after the operation and replaced with synthesized new lens.
Avoiding to fall is more important for female over some age in general.
