A new operation designed to help blind people see again has been tested with success.
Three patients with very poor vision benefited from the procedure, which sees a person's own cells used to heal a damaged cornea.
Researchers from the University of South Wales in Sydney carried out tests, which see stem cells from the eyes grown on a contact lens.
Dr Nick Di Girolamo said: "The procedure is totally simple and cheap. There's no suturing, there is no major operation. You don't need any fancy equipment.
"It requires no foreign human or animal products, only the patient's own serum and is completely non-invasive."
It is hoped by the researchers that the technique could be used on other parts of the eye such as the retina.
As the transplant is created from a person's own stem cells, there is no chance that it will be rejected by the body.
