Sending prayers ~ it's a scary surgery!
Both of my DH's retinas detached last year about this time. One needed surgery and one they did with a laser. It took several months before he could really see well and he just started driving at night again a few months ago.
A year later, he has 20/20 vision in the eye that was fixed with the laser and 20/40 in the eye that needed surgery. He is completely recovered and doesn't even wear his glasses half the time.
