In this special on-location episode recorded in Leuven, Belgium, we sit down with the co-founders and technical leaders of ReVision Implant—Frederik Ceyssens (CEO), Maarten Schelles (CTO), and Laurens Goyvaerts (CSO). The team shares their journey developing a high-density, intracortical visual prosthesis aimed at restoring vision for the blind. From developing reliable insertion technology to achieving long-term biocompatibility in nonhuman primate models, ReVision Implant is at the forefront of neurotech innovation. Tune in to hear about their challenges, breakthroughs, and what’s next in the race to cure blindness through brain stimulation.

Top 3 Takeaways:

Future users of ReVision's visual prosthesis express diverse goals—from navigating unfamiliar cities independently to recognizing familiar faces—highlighting the need for customizable solutions with both wide fields of view and high resolution.
The team is exploring adaptive algorithms that could allow users to toggle between broad, low-resolution views and focused, high-resolution modes—such as reading letters or recognizing faces—offering personalized visual strategies even if only a few thousand stimulation points are achievable.
Restoring vision is one of the most challenging neurotech applications—far beyond simply upgrading existing DBS systems—but taking that bold leap sets ReVision Implant apart in a space where few dare to innovate at this scale.
