Robot eye restores sight

Restoring some sight after two decades of losing sight must feel remarkable. Delvin Kehoe, after losing his sight 18 years ago due to a  disease can now see lights, shapes, birds and even his own face thanks to a remarkable light cell device implanted in his right eye.

The artificial silicon retina implanted into his eye is designed to stimulate damaged retinal cells, allowing the cells to recreate visual signals. Delvin and his twinbrother are only two of six people world wide who have this new device implanted into their eyes.

Dr Allan Chow, the co-inventor believes the technology offers hope to millions of people who have lost their sight from common eye conditions like Macular Degeneration and Retinitis Pigmentosa.

If all goes well the device could be ready for more general use and be available with five years.
