Does Degenerative Disease of the Cornea qualify for SSI benefits?

If you've had transplant surgery recommended, why aren't you having it done? Do they say that will help correct your vision so you can at least have decent vision with gles? I don't know how you can be on SSD unless you've exhausted all treatments for your condition. You would need a couple doctors to "testify" that there is no help for your condition and you are declared too blind to do your normal job. I'm not an expert, though, so you would have to do some web surfing and phone calls to find your answer.
