Blind could be cured by stem cells grown in contact lenses

Researchers say the world breakthrough can "dramatically improve" the sight of patients with damage to their cornea – the clear outer shell of the eye – caused by disease or injury. If early findings bear out then the treatment could be affective for thousands of patients in Britain and is so cheap it could be used for millions more in the Third World. The research team removed tissue with regenerative stem cells from patients' own eyes and then multiplied them in the laboratory on the surface of a contact lens. Telegraph
