Ron's experimental surgery took place at London's Moorfield's eye hospital. A tiny camera mounted on a pair of sunglasses transmits data via a cable to electrodes that sit upon Ron's retinas. When the electrodes are stimulated they transmit messages to the optic nerve in Ron's brain, which in turn allows him to see the light pattern experienced by the camera.
With training, patients will be able to create meaningful images based on the light patterns they can now see. To date, eighteen people have bionic eyes and more will follow.
