Wireless retina implant with optical energy supply
We present the first results of work towards a foil-based epiretinal prosthesis that can stimulate retinal cells. The prosthesis receives trigger signals and energy in the form of high intensity infrared radiation.

Effects on Retinal Stimulation of the Geometry and the Insertion Location of Penetrating Electrodes
Retinal implants have been developed and implanted to restore vision from outer retinal degeneration, but their performance is still limited due to the poor spatial resolution.

Prosthetic Rehabilitation of Completely Blind Subject with Bilateral Customised Ocular Prosthesis: A Case Report [PDF]
The special sensory organs play significant role in our daily lives. Until one of them is totally or partially lost, its real value is not fully appreciated. The most tragic, yet common loss of sensory organ is that of an eye.

Non-fullerene acceptor based photoelectric material for retinal prosthesis
Microelectronic retinal implants can restore a useful level of artificial vision in photoreceptor-damaged retina. Previously commercialized retinal prostheses require transocular connection lines to an external power supply and/or for data transmission ...

First-in-human trial of a novel suprachoroidal retinal prosthesis. [PDF]
Retinal visual prostheses ("bionic eyes") have the potential to restore vision to blind or profoundly vision-impaired patients. The medical bionic technology used to design, manufacture and implant such prostheses is still in its relative infancy, with ...
