Has anyone ever had a 94 year-old relative have cataract surgery?

I'd talk with her primary doctor. Since they don't use a general anesthetic for cataract surgery, it should be okay if she's healthy. There are always risks, but there are risks to not having the cataracts removed, as well. She could become too depressed to enjoy her life because of her increasing vision problems. Also, as our senses (hearing, sight, etc.) diminish, our brain receives less stimulation. That can lead to cognitive issues. If this were me, if my primary physician and opthomologist agree to go ahead, I'd do it. But then I can't imagine not being able to read.
Good luck to her on this. I'd love to have you check back and let us know what she decides.
