Awww, poor Baxter! I don't get the buttons still though. Not sure how medically that would aid the healing, but I am also not a Dr, so there ya go!
My parents boston, Lucy, lost her eye in a fight she got into with my dog Sugar, about 4 years ago. It was one of the scariest traumatic things I have ever witnessed and had to have nightmares about. Lucy's eye was completely knocked out of the socket though (we think Sug caught it with her paw) and apparently eye injuries are extremely common in Bostons. That did NOT make it any easier to forgive Sugar though. Even though, she really is a good dog except her and Lucy hated each other.
Wow, I really went off on my own tangent there. I was just trying to say that I think Baxter will be fine, his eye looks pretty good to me. But even if he were to lose it, he will still be fine. Lucy lived for 3 more years after losing her eye (she was 12 when she passed away), and she was still active and happy and playful up until she got sick.
