Emerging Prostheses Attempt Vision Restoration Low-resolution retinal implants aimed at helping the blind gain mobility are getting ready to appear on the market. From: R&D Magazine - June 2004 - page 30 Numerous researchers are dedicating their time and efforts to develop microelectromechanical systems (MEMS)-based visual prostheses that will improve the quality of life of visually impaired individuals. Three approaches are generally being explored, with the prosthesis being implanted in the brain's visual cortex, the optic nerve, or in the retina. A retinal prosthesis can be fixated either on the retinal surface (epiretinal) or below the retina (subretinal).
