The Alpha IMS is a subretinal implant developed by Retina Implant AG, aimed at restoring functional vision for individuals with retinitis pigmentosa, a group of genetic disorders characterized by progressive vision loss. Implanted beneath the retina, the device features a microchip equipped with 1,500 light-sensitive photodiodes, amplifiers, and electrodes. It functions by mimicking the role of photoreceptor cells: capturing light signals and converting them into electrical impulses transmitted to the brain via the optic nerve.
Alpha IMS enables patients to perceive light patterns, assisting in navigation and object recognition. Clinical trials have shown that the implant can enhance visual perception, marking a significant advancement in vision restoration technologies.
