Hi and welcome to the forum, I'm glad you found us too!
Everyone that uses the scleral lens has dry eye issues so I don't see where it would matter whether you have a neurotrophic cornea or not. As for the cesspool for bacteria, that could be true but I know several of those that have the lens and post here would say that's not an issue. I had the lens for a couple of years and LOVED it. Then I started having allergy issues in the Spring and Fall, I couldn't wear the lens because of the irritation but had to wear the lens to keep the moisture in my eye. My eye doctor thought perhaps I had developed an allergy to the lens. Perhaps your doctor was right and I had to much bacteria under the lens.
I see no reason not to give the lens a try or you could try the lens I use now, it's a daily use lens, put it in my eye in the morning and throw it away before I go to sleep. It's a lens made by Acuvue, it's the Oasys HydraLuxe, costs just under a dollar a lens. To some people that seems like a lot but to me it's nothing compared to the relief it gives me. You might want to do some research on the eye issues category of this board to learn more about both the scleral lens and the daily uses lens. Feel free to ask questions.
