The First Bionic Eye on the US Market

The Argus II Retinal Prosthesis System, developed by Second Sight Medical Products, is expected to be approved by the US FDA (it has already been approved by European Regulators). The bionic eye consists of 60 electrodes implanted in the retina that are sent a signal by a transmitter attached to a pair of glasses with a camera. The camera takes in the image, converts the image to an electrical signal in the visual processing unit worn by the patient, transmits the signal to a receiver attached to the eye, and on to the electrode array that delivers small electrical impulses to the nerves in the retina. Designed for use in patients with retinitis pigmentosa, the bionic eye has allowed patients to regain some level of sight, in some cases including some colour vision, though total vision is limited to a 20° maximum possible field of view.
