A Japanese committee has provisionally approved the use of reprogrammed stem cells to treat diseased or damaged corneas. Researchers are now waiting for final approval from the health ministry to test the treatment in people with corneal blindness, which affects millions of people around the world.

The cornea, a transparent layer that covers and protects the eye, contains stem cells that repair it when damaged. But these can be destroyed by disease or by trauma from chemicals or burns, which can result in patients losing their vision. Currently, cornea transplants from donors who have died are used to treat damaged or diseased corneas, but good-quality tissue is scarce.
