"The approach anticipates a treatment with clear advantages over the usual method of treating corneal blindness, in which a patient's scarred corneas are replaced with healthy tissue from donor corneas. In some cases, the patient's body rejects the transplanted tissue, and donor corneas are in short supply in certain parts of the world, including Africa and Asia."
