I know you would like answers about your recovery but they are impossible to give. The surgery is not unique and typical like cataract surgery. You can use the search feature and archives and scroll through posts over the past week or so and there are many people that have shared their experience with recovery from this type of surgery. Know that most eyes do not recovery full and normal vision. Often the surgeon does not know ahead of time if gas or air will have to be left in the eye. Have no idea what the yellow wrist band is about.
I don't know what type of gas they used in my vitrectomy/scleral buckle surgery, but it lasted about 3 weeks. Yes, I had one of those bracelets. Between the gas bubble and the odd refractive effects it causes, temporary floaters and cloudiness, flashes from residual traction, and other visual effects from the retinal healing, that was a very odd and disconcerting time. Good luck!
