  • Patent number: 11376163
    Abstract: Disclosed are devices, systems, and methods for restoring vision to a subject. In one embodiment, the vision restoration device comprises a projector configured to project one or more digital images onto a central retina of the subject and one or more lenses coupled to the projector and configured to focus the one or more digital images. The vision restoration device can also comprise an extraocular component configured to be implanted within the subject and comprising one or more processors programmed to execute instructions stored in a memory to wirelessly receive the one or more digital images from an extracorporeal device. The intraocular projection component can be connected or coupled to the extraocular component by a trans-scleral communication wire configured to cross the sclera of the eye. The trans-scleral communication wire is configured to transmit digital data between the extraocular component and the intraocular projection component.

  • Patent number: 11091300
    Abstract: A box includes a base and a cover which is removably mounted to the base. The base includes a first room defined therein, and a connection strip extends from the periphery of the top opening of the base. A knob is formed on the connection strip. The cover includes a skirt extending from the periphery thereof so as to form a second room between the skirt and the cover. The skirt includes a U-shaped recess formed in the outside thereof such that the knob can be engaged with the U-shaped recess. The U-shaped recess includes a U-shaped inside wall formed between two outwardly projecting reinforcement ribs on the outside of the skirt to easily accommodate the knob therebetween.
