A number of research groups are developing electrical implants that can be attached directly
to the retina in an attempt to restore vision to patients suffering from retinal degeneration …

▪ Abstract Retinal prostheses represent the best near-term hope for individuals with
incurable, blinding diseases of the outer retina. On the basis of the electrical activation of …

A subretinal visual implant (Alpha IMS, Retina Implant AG, Reutlingen, Germany) was
implanted in 29 blind participants with outer retinal degeneration in an international …

A light-sensitive, externally powered microchip was surgically implanted subretinally near
the macular region of volunteers blind from hereditary retinal dystrophy. The implant …

This book contains pioneering methods in biomimetics. Introducing the principles of using
biology to inspire designs as well as biological mechanisms as models for technology, this …

Objective To determine the safety and efficacy of the artificial silicon retina (ASR) microchip
implanted in the subretinal space to treat vision loss fromretinitis pigmentosa. Methods The …

Stimulating electrode materials must be capable of supplying high-density electrical charge
to effectively activate neural tissue. Platinum is the most commonly used material for neural …

Artificial retina implantation provides an effective and feasible attempt for vision recovery in
addition to retinal transplantation. The most advanced artificial retinas ever developed …

Most of current concepts for a visual prosthesis are based on neuronal electrical stimulation
at different locations along the visual pathways within the central nervous system. The …

Existing epiretinal implants for the blind are designed to electrically stimulate large groups of
surviving retinal neurons using a small number of electrodes with diameters of several …
