Abstract: The present invention pertains to a projector device for projecting a light beam onto a retina of a human eye, comprising a projector for projecting a light beam from the exterior of a human eye through a pupil of the eye, wherein the projector is configured such that an exit pupil diameter of the light beam is set smaller than an eye pupil diameter of the eye, a corresponding method, and a device comprising such a projector device.

Abstract: The task of providing a device which makes it possible for the natural visual faculty of a partially vision-impaired person to be restored or supported as realistically as possible by means of a visual aid or visual prosthesis is achieved with the visual aid according to the invention in that, beyond the pure acquisition of a two-dimensional image, additional information is included in the image processing. For this purpose, a visual aid system is proposed which, during the reproduction of the processed image, visualizes additional information regarding the spatial position and/or specific attributes of objects in the acquired image which is associated with objects in the acquired image.

Abstract: The present invention provides a plug device or grommet (1) for sealing an incision in tissue of a human or animal body, such as an incision in the tissue of the sclera (S) made during a surgical intervention for the implantation of a visual prosthesis. The device (1) comprises: a cover part (10) for covering the incision and an area of the tissue (S) around the incision; and an insertion part (20) extending from the cover part (10) for insertion into the incision through the tissue (S). The insertion part (20) defines a sealable passage (30) which is adapted to extend through the incision, and the insertion part (20) is preferably flexible and resiliency deformable to open and close the sealable passage (30) there-through. The sealable passage (30) extends through the incision to provide communication between an outer side (S0) of the tissue and an inner side (Si) of the tissue. The passage (30) may accommodate a component which provides a connection or interconnection through the tissue (S).
