Fuchs' dystrophy is also called fuchs' endothelial dystrophy, which is a slowly processed corneal disease. It is more common in women in stead of men, but it seldom impact the vision of people under 50s. It is a genetic disease that many genes and loci contributed to the risk. Once it becomes severe, a corneal transplant is required to restore vision. Now it is recommended to use therapeutic soft contact lenses to treat fuchs' dystrophy. Normally we think it is not a good idea to wear contact lenses when there is a problem with cornea, but actually the therapeutic soft contact lenses could help protect the ocular surface and closure of epithelial wound. But the therapeutic soft contact lenses are different from the common ones. It is wore on a continuous basis. To get more information, you should consult the eye specialist. The sooner the better. Once corneal scarring is formed, a surgery is required to transplant a healthy cornea from a donor to restore the vision.
