Eye Implant Made From Pig Skin Reverses Blindness in 14 People
16th August 2022
The challenge: The cornea is a tough, transparent layer of tissue that covers the front of the eye. It helps focus light on the retina, and if it’s damaged by disease or injury, a person’s vision can suffer — worldwide, nearly 13 million people are blind due to problems with their corneas.
For people with keratoconus — a disease that causes the cornea to thin and bulge out — the only way to correct severely impaired vision is with a cornea transplant from a human donor.
