The cornea is the transparent frontmost layer of the eye that both protects it and helps us see clearly by focusing light on the retina. When people’s corneas are scarred by serious injury or infection, doctors can usually treat it by transplanting healthy corneal tissue from a donor, also known as a corneal graft.

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.

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