@John57 - Yes, many people experience loss of vision from cataracts, and once they are removed are able to see much clearer. It is also not uncommon for them to have them removed more than once from the same eye.
I consider those who have loss of vision from cataracts much more fortunate than those who have macular degeneration.
My mom has always been an avid reader and always said as long as she had her vision and could read, she would be happy.
Unfortunately, she has developed macular degeneration in both eyes and now has trouble seeing very well at all.
Her dimming of vision was something that happened gradually, so she was somewhat able to prepare herself for it. It still doesn't take away the frustration of not being able to see and do things that you loved to do.
There are some devices that help and enable her to stay in her own home, but she really misses being able to pick up any book or magazine and read it.
