Actually I had no idea beforehand that there would be a gas bubble / retina damage to be fixed! The initial problem had been infection in the eye with debris in the gel blocking vision, so for the last month any examination of the retina was a challenge, and the only possible observation seemed to be ultrasound.
I do have a head rest on order from amazon (appears to have a donut shaped hole that your face fits into) which should arrive by 10pm tonight.
I'm also beginning to see a tiny bit

I can detect fingers moving in front of my face!
