Abstract: Apparatus and methods are described that project images onto the retina of an eye. The apparatus can include an image memory element for storing an image signal representative of a visual image, a projection element in electrical circuit with the image memory element for generating an optical image signal of the type suitable for detection by a retina and being representative of the visual image, and a focus element that is adapted for implantation into the eye at a position in the eye which is posterior to the cornea and anterior to the retina and that is optically coupled to the projection element for focusing the optical image onto the retina. The projection element can include a display device that is dimensionally adapted for disposition within the eye at a position posterior to the cornea.
