JanetB, I don't know anyone who has had that surgery, but I also wish you well. I was extremely fortunate that my retinal problem was caught very early, before there were any symptoms, and could be corrected via laser surgery. I trust that your recovery will be as complete as mine was; i'm just sorry that you have such an ugly recovery process. I'm sure you've already thought of books on tape.
This sounds like the sort of surgery that requires anesthesia. Be sure you are set up in advance with good anti-nausea meds and clear instructions for their use, just in case. I think ginger ale helps, too. (Have straws on hand.)
