the center of the V-shaped columnar shell 1 is a hollow channel, and the three top ends of the V-shaped columnar shell 1 are all arc-shaped, and are respectively provided with a micro display screen 2 close to the upper eyeball wall, a concave mirror 7 close to the lower eyeball wall and formed by a reflecting coating and a light-transmitting film 6 close to retina; the micro display screen 2 is connected with a mechanical control module of the micro display screen 2; the image receiving module receives external image information, including images acquired by an external camera, images transmitted by a cloud server and images stored locally, and the images are processed by the image processing module and then transmitted to the micro display screen 2 in the intraocular implant to display the image information. The control module can control the receiving mode of the image receiving module and the processing mode of the image processing module, and meanwhile, the micro display screen 2, the micro display screen mechanical module 3 and the concave mirror mechanical module of the intraocular implant are also controlled by the control module.
Working principle:
the V-shaped columnar shell 1 is implanted between the eye lens and the retina, and is close to the middle and the rear of the retina, and the center of the shell is a hollow channel so as to reflect and collect light rays of the micro display screen 2 to reach the retina. The three top ends of the V-shaped shell are all arc-shaped, and a micro display screen 2 close to the eyeball wall at the upper end, a concave reflector 4 close to the eyeball wall at the lower end and a light-transmitting film 6 close to retina are respectively placed. In particular, the micro display 2 and the concave mirror 4 comprise a mechanical control module of the micro display 2 and a mechanical control module of the concave mirror 4, respectively. The mechanical control module can controllably rotate to control the angle formed by the device and the eyeball wall, so that fine adjustment of the projection position of the light after implantation is jointly realized, and the optical projection errors caused by the production process and the implantation process are corrected.
The intraocular implant device implanted in the eye converges and projects light of the micro display screen 2 to the retina through the light-tight V-shaped cylindrical housing 1. When the device is in a working state, the processed external image is transmitted to the micro-display screen 2 in real time, the image is focused and reflected by the concave reflector 4 arranged at the bottom side of the V-shaped channel and close to the lower part of the eyeball wall, the image is precisely imaged at a retina selected area by the mechanical control module of the micro-display screen 2 and the mechanical control module of the concave reflector 4, and the light stimulates cone cells and rod cells of the retina through a natural retina vision path, so that signals are transmitted to the vision cortex, and finally a wearer perceives the image information displayed by the micro-display screen 2.
The device has two forms: one is a device with a mechanical control module for the concave mirror 4, where the device can precisely image the image information on a specific area of the retina by adjusting the mechanical control module for the micro-display 2 and the mechanical control module for the concave mirror 4 in combination.
