Indications
Principle
- replaces rod & cone photoreceptor function in patients with retinal degeneration through stimulation of secondary bipolar neurons & ganglion neurons in the retina
Procedure
- combines an artificial retina with electrodes implanted in the patient's eye and a set of eyeglasses fitted with a miniature video camera & transmitter
- data from the video camera are transmitted wirelessly to the electrodes, which convert the signals into electrical impulses that are carried down the optic nerve to be read as images by the brain
