Good Morning Miss G.
Your dad after the operation wont be a patient man.bur we all different.
I had RP operation last December
I had to sleep about 2 weeks on the sofa in my living room.it wasn't comfy initially but because of the catheters was attached to my body It was more convenient for me to sleep on the sofa first 2 weeks until the catheters came off.
TV was the great time company for me
Surely your dad wont be comfy to read books first 2 weeks so make sure the TV is always stand by for him.
A companionship is very important as you stated you dont live closer to your dad so make sure he has got plenty foods to eat.
We were told after the operation we must consume high energy foods-drinks while,green stuff ,steak, smootie etc.
A bucket can be practical to place the night bag next to the bed/sofa.
I like to listen music but after the operation I preferred to watch TV-movies more than the music. A TV can be a great company really. Especially until the catheters comes off .
So sorry that I cannot give more advises.
Good luck to your dad with his future.
Ps after the operation he must not force himself to lift even a pint of milk.
