5 Surgeries From Detached Retina. Left With Bag of Fat Under Eyes?

I had 5 surgeries on my left eye from a detached retina. I have a scleral buckle around my eye for the rest of my life. I am left with a bag of fat under the eye. However it is not on my right eye. Needless to say I look very bad with just one large bag under one eye only. Medicare will not cover it because it is cosmetic. It would be cosmetic if I asked for both eyes wouldnt it? The bag is obviously caused from trauma to the eye because my other eye is fine. What can I do?
