Retinal implants or bionic eye?

Record producer Robin Millar started losing his sight in the mid 1980s as a result of retinitis pigmentosa.
The condition resulted in the loss of the photo-receptor cells at the back of the eye, leaving him completely blind.
Mr Millar is one of two British patients to have a electronic retinal implant fitted, which sends electrical impulses to the retina. They then have to be interpreted by the brain.
His surgery was carried out at King's College Hospital, London.
He showed the BBC's Medical Correspondent Fergus Walsh how it works.
