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 irreve

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.

Stem cell therapy is emerging as a promising treatment for blindness and eye damage, giving hope to those with severe vision loss.

Surgeons took stem cells from a healthy eye and transplanted them into the injured eye, successfully repairing "irreversible" damage.
