Scientists at the University of Melbourne have successfully implanted a special film on the corneas of sheep to restore their vision. The technique may offer an alternative to cornea transplants in people, which are in short supply and can be rejected by the host’s immune system.
The cornea—the vision-focusing layer at the front of the eye—uses specialized cells to pump out water, keeping itself clear. The eye can’t repair these cells when they are damaged by age, injury, or illness.
