So I know that there a fair number of us that have faced, or will face, decisions about cataract surgery. There are a range of issues that surgeons rarely bring up when encouraging patients to have a sense replacement, mostly because these things never occur to them or affect a small percentage of the population.
Lens Tyoes: Just like glasses, cataract lenses replacements come in different focal length configurations. Many of vision challenged folks use mulitfocal lenses which allow you to have only one pair of glasses for various tasks, and there are multifocal cataract lenses as well. For many who choose a multifocal lense replacement you are going to run into distortion and artifacts in your vision when trying to do visual astronomy, and you cannot simply take them off as they are inside your eye.
I encourage up you to take a few minutes to watch this Utube video on the 5 regrets patients have with cataract lenses.

My own experience, despite my Dr suggesting cataract replacement lenses, was to stick with my multifocal glasses, on the basis that I can remove them for visual astronomy, and still enjoy good vision whole driving (ie being able to see the dashboard).
Of course if you are suffering with vision clouding, or colour distortion, single focal lense replacement would make sense, and you can always get a pair of reading glasses, but driving will be seriously impacted.
If you have had cataract surgery, please let us know how your handling the transition as it relates to astronomy.
