If she's traditionally used toilet paper, perhaps install a bidet attachment? Not to be gross, but it could make her require less help after using the bathroom. It also means she won't be dependent on someone hunting down a roll of toilet paper if she runs out. Caveat: I have no experience dealing with eyesight-related disabilities. So I'm just guessing.
