Prosthetics and 'Wearables' Research News
Scientists have developed a retinal implant that can restore lost vision in rats, and are planning to trial the procedure in humans later this year. The implant, which converts light into an electrical signal that stimulates retinal neurons, could give hope to millions who experience retinal degeneration – including retinitis pigmentosa – in which photoreceptor cells in the eye begin to break down, leading to blindness.
The prestigious Institute of Ocular Microsurgery in Barcelona implanted the first patient in Spain with IRIS® II, a bionic vision system equipped with a bio-inspired camera and a 150-electrode epi-retinal implant that is designed to be explantable.
Not just Star Trek fiction, a new visor from eSight is a lightweight, high-contrast vision system for legally blind people.
The artificial retina is the first device of its kind to move from the laboratory to the clinic, after a trial of 30 patients has shown that it can safely restore some vision to people who have lost their sight to a genetic disease.
This article describes and compares two retinal implants, one being developed in Israel to the one in clinical trials in the U.S. by Second Sight. While they are both implants, they are also very different. Users of the Israeli one would wear just a special pair of glasses, whereas the Second Sight one includes glasses, a camera, and a processor. In addition, surgery for the Israeli one takes much less time and is less invasive. The Israeli inventors also promise much better vision. It is expected to begin clinical trials in 2013.
Researchers have developed an implant that clears out the scar tissue of diseased retinas and seeds new ones. This quickly evolving procedure holds hope for millions of persons with retinitis pigmentosa (RP) and age-related macular degeneration (ARMD).
ScienceDaily — Researchers trying to restore vision damaged by disease have found promise in a tiny implant that sows seeds of new cells in the eye.
Less than a month ago, at the 2009 International Electron Devices Meeting (IEDM), researchers from Stanford University presented their solution for a retinal implant that has the potential to restore vision in those who lose sight due to age-related macular degeneration (AMD), retinitis pigmentosa (RP), and certain other retinal disorders. The implant is composed of solar cells embedded in a bed of flexible silicon electrodes that transfer visual images to the brain.
New York Times article outlining a number of experimental treatments being tested to help restore vision. An intensive three-year research project involving electrodes surgically implanted in the eye, a camera on the bridge of the nose and a video processor strapped to the waist is part of a burst of recent research.
Led by electrical engineering professor John Wyatt, team develops retinal implant that could help restore useful level of vision to certain groups of blind people. Inspired by the success of cochlear implants that can restore hearing to some deaf people, researchers at MIT are working on a retinal implant that could one day help blind people regain a useful level of vision.

Very little research-based information exists about the benefits and challenges of cochlear implants for children who are deaf or hard of hearing, who also have a vision impairment. A new study aims to remedy that. This multi-year project will address a number of objectives to begin to provide a research base for more informed decision-making by families and service providers, in relation to cochlear implants for children who are deaf-blind.
