Definitely see if there is some academic-affiliated eye center that you can go to, if you haven't done so already. They'd be the most knowledgeable on the matter. The Moran Eye Center, where that lady had her eyes reconstructed, is affiliated with the University of Utah. They also restored my father-in-laws sight after his stroke, even though he was told it couldn't be done. I'm not trying to criticize non-academic eye doctors - most of them do a great job with typical problems such as glasses, lasik, cataract removal, etc. But these unusual types of problems are best handled by people in highly specialized clinics. Even when my father in law went to the Moran Eye Center, the first doctor told him that he didn't think it could be done, and he was referred from specialist to specialise until the third or fourth guy ended up being an expert on the type of damage he had suffered.
In other words, ask your eye doctor if he knows of an expert on your condition. If not, try to look for one on the internet and get e referral to him. I would think that second opinions on a probllem like this should be covered by insurance. And I think that you should be tenacious about getting another opinion, as some of these types problems need to be fixed early on.
