Blind Patients Regain Vision via Retinal Chip

🔑 Enhanced Key Takeaways

• •Science Corporation raised $230 million in Series C funding to accelerate PRIMA commercialization and expand clinical trials to Stargardt disease and retinitis pigmentosa[2][4].
• •PRIMA implant features 378 light-powered pixels in a honeycomb pattern, converting infrared light from glasses into electrical signals to stimulate retinal neurons[5].
• •NEJM editorial described PRIMA as the first treatment in clinical trials to successfully restore functional vision in advanced geographic atrophy due to AMD[4].
• •The implant requires surgical placement under the retina and post-activation training lasting months for patients to adapt to restored vision[7].

🛠️ Technical Deep Dive

• •Implant dimensions: 2mm x 2mm x 30µm, subretinal photovoltaic array acting as artificial photoreceptors[1].
• •378 independently controlled pixels in honeycomb pattern; each pixel converts near-infrared light to electrical pulses via electrodes contacting bipolar cells[5].
• •Specialized glasses include front-facing camera, eye-facing infrared projector for power/data delivery, pocket processor for zoom/brightness, and sun lenses[1][5].
• •AI algorithms in post-surgery activation process the visual scene to focus infrared projection on key objects[6].
