Bionic eye 'blindness cure hope'
The AMD disease leads to a progressive loss of sight
A 'bionic eye' may hold the key to returning sight to people left blind by a hereditary disease, experts believe.
A team at London's Moorfields Eye Hospital have carried out the treatment on the UK's first patients as part of a clinical study into the therapy.
The artificial eye, connected to a camera on a pair of glasses, has been developed by US firm Second Sight.
It said the technique may be able to restore a basic level of vision, but experts warned it was still early days.
The trial aims to help people who have been made blind through retinitis pigmentosa, a group of inherited eye diseases that affects the retina.
