Those relatives of mine who had cataract surgery are long dead. You are correct in identifying me as a Brit, but I've lived in the USA for more than 20 years, and I'm talking about operations that took place maybe 30 years ago.

Nonetheless, it sounds like the modern artificial lenses actually change focus like natural ones, which is, if you'll forgive the pun, an eye opener! The lenses available when my grandparents were alive didn't do that. I wonder if it iis just that the old lenses were too hard and inflexible, or if they have also changed the way that they are attached? Perhaps only an eye surgeon (and maybe an old one at that) would really be able to answer that question.
