Electronic Retina Eye Implant Helps the Blind See Again

Two British men who have been totally blind for many years have had part of their vision restored after surgery to fit pioneering eye implants.

The two patients, Chris James and Robin Millar, lost their vision due to a condition known as retinitis pigmentosa, where the photoreceptor cells at the back of the eye gradually cease to function.

The wafer-thin, 3mm square microelectronic chip has 1,500 light-sensitive pixels which take over the function of the photoreceptor rods and cones.

The surgery involves placing it behind the retina from where a fine cable runs to a control unit under the skin behind the ear.

Synopsis: A British man who has been totally blind for many years has had part of his vision restored after surgery to fit a pioneering eye implant.

The device, which was fitted behind the retina, has enabled Chris James to perceive light and even some shapes.

The BBC’s Fergus Walsh reports.
