Settings in the viewfinder is easy since you are already adjusting the viewfinder diopter. Looking at menus can be more of an issue if you have to use them. For some cameras, there are many items accessible with the numerous buttons, and/or you can program existing buttons to make changes. This requires practice and good muscle memory, but does avoid chimping at the menus to make desired changes. Me, I just keep reading glasses in my pocket and use if/when needed
When I had my cataracts replaced I chose distance lenses, but due to horrible astigmatism I have to wear glasses anyway. To read menus in cameras I carry a cheap pair of readers in my pack at home I use trifocals but I never wear my trifocals in the field since the ground is so out of focus through either close focus lens that I'd fall flat on my face (again).
I'm just the opposite - I've got cataracts just really starting. I'm trying to get my eye doctor to do the surgery before I have visual impacts!
You almost certainly won't get an ophthalmologist to operate before it's necessary. The risk of complications from surgery is very small, but it's there so most doctors won't risk it -- you shouldn't either.
