Advancing the field of vision restoration: Our science and technology breakthroughs.

Phosphoenix’s solution provides comprehensive visual field coverage through high-density, ultra-flexible probes, stimulating nerve cells in the brain to generate functional low vision.

Science & Technology

Interfacing with the brain

Blindness affects ~40 million people thoughout the world, and is set to increase due to the ageing population. Leading causes in the developed world include age-related macular degeneration, diabetic retinopathy, and glaucoma.

Our prosthesis bypasses the eyes and interfaces directly with the brain. The user would wear a pair of glasses equipped with a camera, that sends the video feed to a pocket processor. Advanced AI techniques convert video footage into instructions for electrical stimulation in real time. Our brain implant applies tiny electrical pulses to the visual system, inducing artificially generated percepts in the form of dots of light, known as ‘phosphenes.’ Generation of multiple phosphenes creates an interpretable image, akin to a constellation of stars in the night sky.

Our breakthrough innovations

Previous pre-clinical work on vision restoration

Recent discoveries at the Netherlands Institute for Neuroscience (NIN) show that newly developed high-resolution implants in the visual cortex make it possible to recognize artificially induced shapes and percepts. Our findings were published in the leading academic journal, Science  (Chen et al, 2020).

These results led to the founding of Phosphoenix in 2019. Our company’s mission is to build a neuroprosthetic device that would allow profoundly blind people to regain functional vision and to recognize objects, navigate in unfamiliar surroundings, and interact more easily in social settings, significantly improving their independence and quality of life.
