Assistance For Low-vision Father (home Dialysis Supervision & Home Help)

My father has very poor vision. He knows the process for setting up, connecting to, and disconnecting from home dialysis, but may need assistance from a person with better vision to complete all steps on his own. He lives with me so I usually assist with this, but sometimes have to travel for work, so I need someone to help on occasion with supervising his dialysis connection at night in particular, around 9 p.m. We will train. I could also use help with getting him to appointments on occasion, and help with meal prep every now and then would be great. The appointment and meal prep help is not the most pressing, though. Thanks.
