Restoring eyesight with retinal implants

Experimental trials of retinal implants are showing promising results. Three companies are getting closer to commercial availability of retinal implants, that restore some sight to blind people. When these implants get more advanced they would probably have applications for people with normal sight. Enhanced vision capabilities, like geotracking apps and HUDs  could become a reality in the coming decade.

Retinal Implant AG from Reutlingen, Germany has announced the results of the first human trial of its subretinal implant. Eleven patients who lost their sight due to retinitis pigmentosa received the implant through surgical transchoroidal implantation. Energy was delivered to the implant via a retroauricular plug.

Just a few months after receiving $42 million from the Australian government, Bionic Vision Australia (BVA) unveils its prototype bionic eye, which researchers hope will enable users to perceive points of light that the brain can reconstruct into images. Announced this week at the University of Melbourne, the wide-view neurostimulator concept was developed by researchers at BVA and the University of New South Wales for patients with vision loss due to retinitis pigmentosa or macular degeneration.
