Phosphoenix

A New Approach to Vision Restoration

Phosphoenix is developing a novel neuroprosthetic approach to restore functional vision in people with profound blindness by directly stimulating the brain’s visual pathway. At the core of this approach is the Fountain Probe™, a high-density, ultra-flexible neural interface designed for precise stimulation of the brain.

Restoring Visual Perception through Targeted Neurostimulation

Restoring vision remains a central challenge in neurotechnology, driven by the need for high information bandwidth, structured spatial encoding, and wide visual field coverage. Phosphoenix addresses these constraints by targeting the lateral geniculate nucleus (LGN), a compact and retinotopically organized relay within the visual pathway. This approach leverages the intrinsic structure of visual processing, while focusing on a clinically accessible deep brain target. By interfacing at this level, the system provides a fundamentally different route toward restoring functional vision.

From Neural Stimulation to Functional Vision

Electrical stimulation of the LGN evokes localized visual percepts (phosphenes). By coordinating activation across
multiple electrodes, these can be combined into structured spatial patterns. This approach has the potential to support basic visual functions such as navigation and obstacle detection, contributing to greater independence in daily life. The goal is not to restore natural sight, but to enable functional vision in real-world settings.
