Hi earl25,
Sorry, for what you are going through, and for the different, inconclusive opinions you are getting from doctors. Based on the observations of a layperson, the implants have to be a less risky route, right? So long as you are not having any bite issues, pain issues, or functional issues, wouldn't implants be the way to go?
If you go with the other option, may I suggest that you make sure your private disability insurance is solid. I'm sure you would be completely fine, but I know I would personally feel a lot better knowing that I would be protected (or as protected as possible) if things were to go south. (There's no way I could do my job without my sight; and I'm sure the same goes for pretty much everyone else.)
Good luck with everything.
