The retina implant developed by IIP combines medicinal and information technology with micro-systems technology.

A blind patient has a unique microchip implanted in their eye, wears special glasses with an integrated camera and carries a microcomputer on a belt around their waist.
Visual information received by the glasses is converted into electrical pulses by the microcomputer and the pulses then used to stimulate the patient’s optic nerve. The implant helps restore limited eyesight to people affected with specific hereditary blindness.
