Pixium Vision has developed a system that helps people with vision loss regain some sight through a tiny implant and specialised glasses.
Pixium Vision is bringing new possibilities to people with sight loss with their development of The Prima System. The Paris-based startup was founded in 2011 and has since been dedicated to helping people with vision loss see using bionic vision advancements.
This exciting advancement in bionic vision uses an implant combined with camera-mounted glasses to help people see. The tiny implant is 2 x 2mm and 30 microns thick. The implant is wireless and powered by an infrared light delivered by the glasses. Surgeons can perform the minimally-invasive subretinal implantation procedure under local or general anaesthesia.
The small camera on the patient’s glasses captures the scene around the wearer. The information is sent to a small computer that processes the scene using an AI algorithm and sends it back to the glasses. The glasses use a miniature projector that transmits data to the implanted chip through pulses of infrared light. The implant converts the instructions into electrical stimulation, which triggers the inner retina nerve cells, allowing the patient to process the information visually.
