Embodiment Construction

[0066] Hereinafter, the present invention will be explained in more detail with reference to the accompanying drawings. In the drawings, similar elements are denoted by the same reference numerals and repeated descriptions thereof may be omitted to avoid redundancy.

[0067] figure 1 is a schematic perspective side view of a system 80 for projecting an optical pattern of interest onto the retina of a human eye, according to a preferred embodiment. The system 80 includes a support frame 50 which substantially comprises the form of an eyeglass frame and which can be worn by a patient having a photosensitive retinal implant implanted in his eye or having a genetically corrected retinal area. The system 80 also comprises a projector device 1 adapted to project a pulsed output beam reflecting an optical pattern of interest into a human eye, and a camera 6 for capturing images. According to the preferred embodiment, the camera 6 is integrated and / or aligned with the projector devi...

Abstract

The present invention pertains to a system (80) for projecting a pattern of interest onto a retinal area of a human eye, containing a carrying frame (50) for being worn by a patient, a camera (6) for capturing an image, a projector device (1) for projecting a pulsed light beam (4) reflecting a pattern of interest (44) into a human eye, and a processor device (60) being in communication with the camera (6) and the projector device (1), wherein the processor device (1) is adapted for converting the image captured by the camera (6) into the pattern of interest (44) being basis for the pulsed light beam (4), wherein the projector device (1) and the camera (6) are attached to the carrying frame (50).

Description

technical field [0001] The present invention relates to a system for projecting a pattern of interest onto the retina of a human eye, in particular for projecting a pattern of interest onto an area of ​​the retina of the human eye. Background technique [0002] Retinal dysfunction, especially as a result of degenerative retinal diseases, is a leading cause of visual impairment and even blindness. [0003] To at least partially restore a patient's visual function, it is known to correct areas of the retina by using retinal implants or in other words retinal prostheses. In this regard, several different types of retinal implants based on different operating principles are known. [0004] What retinal implants have in common is that they are usually placed in the patient's eye either suprachoroidally, preretinally or subretinally so that they can replace, ie affect, damaged photoreceptors. In this regard, information about the visual scene is captured by a camera and then tra...
