AI Technical Summary

Problems solved by technology

[0013] Difficult to adjust the irradiance to a suitable level as the beam reaching the retina contains unknown irradiance
Therefore, damage to the targeted area or insufficient impact on the targeted area can result from too high or too low irradiance, respectively

Embodiment Construction

[0088] Hereinafter, the present invention will be explained in more detail with reference to the accompanying drawings. In the drawings, the same elements are denoted by the same reference numerals and repeated descriptions thereof may be omitted to avoid redundancy.

[0089] figure 1 is a schematic side view of a projector device 1 for projecting a light beam 100 onto a retina 114 of a human eye 110 according to a first embodiment. In this exemplary embodiment, light beam 100 includes wavelengths in the near infrared field (NIR).

[0090] The projector device 1 includes a projector 2 for projecting a light beam 100 from the outside of a human eye 110 through a pupil 111 of the eye 110 . The projector 2 is configured such that the exit pupil diameter 102 of the exit pupil 101 of the light beam 100 is set smaller than the pupil diameter 112 of the eye.

[0091] Thereby, it is ensured that substantially the entire energy of the light beam 100 enters the eye 110 through the pu...

Abstract

The present invention pertains to a projector device (1) for projecting a light beam (100) onto a retina (114) of a human eye (110), comprising a projector (2) for projecting a light beam (100) from the exterior of a human eye (110) through a pupil (111) of the eye (110), wherein the projector (2) is configured such that an exit pupil diameter (102) of the light beam (100) is set smaller than an eye pupil diameter (112) of the eye, a corresponding method, and a device (40) comprising such a projector device.

Description

technical field [0001] The invention relates to a projector device for projecting a light beam onto the retina of the human eye, a corresponding method and a device for projecting a light beam onto the retina of the human eye comprising such a projector device. [0002] technical background [0003] Retinal dysfunction, especially caused by degenerative retinal diseases, is a leading cause of impaired vision and even blindness. [0004] In order to at least partially restore the visual function of a patient, it is known to modify areas of the retina by using retinal implants or in other words retinal prostheses. In this regard, several different types of retinal implants are known, which are based on different operating principles. [0005] What retinal implants have in common is that they are usually placed epiretinally or subretinally in the patient's eye so that they can effectively replace damaged cells, such as photoreceptors. In this, information about the visual scen...
