Abstract: An apparatus for selectively stimulating one or a number of nerve cells in the defective retina of a human eye employs a portable laser source whose beam is projected onto the retina via the natural lens of the eye. The laser unit and system controller can be conveniently carried in a small container at the waist with connections made by coaxial and fibre-optics cables to a prosthetic assembly in the form of conventional spectacles. These incorporate a photosensor array for detecting the wearer's forward environment, a fixed focusing mirror and a beam steering reflector responding to signals from a pupil position sensor which combine to regulate stimulation of the appropriate retinal neurons.
