ReVision Implant is a Belgian neurotechnology company focused on developing a cortical visual prosthesis to directly transmit camera images to the brain, with the aim of restoring vision to people who are blind. The company is developing a device that stimulates the visual cortex directly, bypassing the eye and optic nerve. Founded in 2020, ReVision Implant aims to combine brain implants, neurosurgical tools, and image processing to enable meaningful artificial vision through brain stimulation.
History
[edit]ReVision Implant was founded in 2020 by its CEO Frederik Ceyssens and is based in Leuven, Belgium. The company emerged from earlier academic research in flexible electrode technology and neurostimulation at KU Leuven. In 2022, it received a grant from the European Innovation Council to fund further technology development and preclinical testing.[1].
In 2025, the company announced their intent to conduct first-in-human clinical trials in the coming years with their Occular visual prosthesis, with a first test planned at the end of 2025[2]
Technology
[edit]ReVision Implant is developing an intracortical visual prosthesis, a brain implant that delivers electrical stimulation to the visual cortex, the part of the brain responsible for processing visual information.
Unlike retinal implants that require a partially functioning retina or optic nerve, ReVision's approach targets the visual cortex, making it suitable for blind people who suffer from causes of blindness in most parts of the visual pathway.
The system includes:
- A flexible electrode array inserted into the primary visual cortex. By electrically stimulating the brain through these electrodes, visual perceptions (phosphenes) are induced.
- Implantable electronics connect to the electrode array, providing control over the flexible electrodes. This also includes a transcutaneous wireless power and data link.
- An external pair of camera glasses, which capture the environment and convert a video stream into electrical stimulation patterns.
The device is designed to combine phosphenes into coherent shapes, potentially enabling blind individuals to navigate their environment or recognize faces.
Public reception
[edit]ReVision Implant has received attention in Belgian media, particularly in the context of a growing European brain–computer interface ecosystem.[3][4] It has been discussed alongside other neurotechnology initiatives as a potential contributor to treatments for blindness and neural disorders.
