Abstract
The present disclosure is directed to systems and methods for treating retinal dystrophy and retinal degenerations. The disclosure describes retina device comprising a first component including an energy conversion and an interface layer comprising gold nanoparticles and a second component including a light-shutter valve (LSV) configured to operate as a neurostimulator.
Claims20
An artificial retina device comprising:
- a first component including an energy conversion and an interface layer comprising gold nanoparticles;
- a second component including a light-shutter valve (LSV) configured to operate as a neurostimulator;
- wherein the first component is implanted in a patient, and the second component is separate from the first component,
- wherein the first component further comprises a composite dielectric layer selected from a group consisting of polyvinylidene fluoride (PVDF), polyvinylpyrrodidone (PVP), and BaTiO2.

(canceled)
A method of using a retina device comprising:
- determining an intensity of incident light on a retina,
- operating a light shutter valve at a frequency configured to align with the intensity of the incident light,
- wherein an increase in frequency increases a nerve excitation pulse on the retina.
A method of implementing a retina device comprising:
- receiving a controlled hue of light by utilizing a conversion and interface layer,
- generating a voltage with the intensity and duration enough to excite retinal ganglion cells (RGCs), and
- correcting vision in a user by utilizing an energy conversion and interface layer and a light shutter valve (LSV).
