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

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

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.

Transplanted epithelial stem cells from a healthy eye repaired irreversible corneal injury and restored at least partial vision in more than 90% of patients, a preliminary clinical study showed. Within 3 months of the transplant,

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.
