Thanks for your stories and thoughts, everyone!
I passed my one week post-op evaluation this morning. All is going well. The gas bubble is now almost halfway down my field of vision when standing, and I was able to zip through the eye chart. Since the gas bubble still interferes with roughly half of my vision, it can sometimes be quite a strain to focus. But it's improving every day. As long as things continue to improve, (as I expect they will) I won't see the doctor for another 4 weeks.
I am very thankful that my procedure worked out so well.
