An experimental stem cell therapy reversed corneal damage in half of the participants from a recent clinical trial.

Sight-robbing injuries to the cornea can be repaired using a groundbreaking experimental stem cell treatment, a new study shows. The cornea -- the clear outermost layer of the eye -- can become irreversibly damaged if injury or disease destroys its ability to regenerate new cells.

In most cases, the therapy—a transplant of stem cells from the person’s other healthy eye—appeared to safely restore the surface of people’s severely damaged corneas, often improving their vision as well.
