The Alpha IMS is a sub-retinal implant developed by Retina Implant AG. It is a new treatment option for patients in the UK with retinitis pigmentosa who are blind, to help restore vision.
Alpha IMS is a 3×32mm wireless microchip that features a 1500 pixel resolution. The microchip captures light and in turn stimulates the optic nerve, which delivers visual signal data to the brain. The patient is able to see a black and white image. To adjust the brightness, a dial is fitted just behind the ear and the Alpha IMS is powered by a wireless pocket battery.
