    The retinal implant developed under the lead of Doheny Eye Institute demands extensive surgery. The complicated insertion of several components takes six hours. So far, formerly blind people using the system have been able to detect simple shapes, objects and movements. Driving a car or reading a newspaper is still many years away.

  • Structure of the eye

    In an eye suffering from age-related macular degeneration or retinitis pigmentosa, the photoreceptors of the retina die and eyesight is lost. A company called Optobionics is working on a chip that would be placed behind the retina, stimulating dying photoreceptors to continue translating light into neural signals.

  • Optobionics chip

    The Optobionics Artificial Silicon Retina chip, here seen on a penny, is just a few millimeters in diameter and thinner than a human hair. The chip's surface is covered with microscopic solar cells that gather energy from light entering the eye.
