I had cataract surgery for my right eye about 7 years ago. Going blind in my right eye in my early 30's was incredibly unlucky. However, for visual astronomy the view in the eyepiece is better then ever for clarity and especially colour rendition of stars and the planets and even bright nebula. The lens did induce some minor astigmatism but I can observe with or without my glasses. The lens only focuses to 50-60cm meters and I need glasses for driving obviously. The specialist suggested this as its about the distance of your monitor at your work desk tends to be and is a useful focal distance. Of course at the time my left eye was perfectly fine and filled in the other gaps.
But now, at 39 my left eye is starting to cloud a little bit. My right eye came on very quickly where the left one is slower. I think this time I'll use a multifocal lens if my left eye gets much worst. That being said, I had been a left eye observer until I was 38 years old when I started to detect light scatter on bright objects. I switched to my right eye for visual and realised there's something wrong with my left eye.
I wish I switched over to my right eye for visual observing several years ago since it has a lens that will never cloud or dull and from what I've read -has the clarity of the eye of a child.
