How long did the surgery last? My experience so far is that you can get a maximum of about one hour battery life from Glass when using video.
Was the resolution and video quality sufficient for the remote surgeon to really see what was going on? Again, personal experience only, but everyone I've made a video call with over Glass has reported very choppy low-res streams.
I'd love a lot more details on the procedure, what went right and what could have worked better, and just how it was done. "This thing happened" isn't a lot of useful information.
