Adaptive Interfacial Materials and Implants for Visual Restoration

Abstract

AbstractBlindness is a globally critical challenge for public health, affecting more than 43 million individuals worldwide. Retinal degenerative diseases including retinitis pigmentosa and age‐related macular degeneration, involving degeneration of retinal pigment epithelium (RPE) and thereby the dysfunction of retina, are primary causes of blindness. For treating these retinal degeneration diseases, emerging interfacial materials and implants that can adapt to nerve tissues and stimulate residual neurons within the visual pathway have shown particular promise, where some issued products are approved for commercialization. Given the attractive opportunities and challenges of the interfacial materials and implants for visual restoration, a comprehensive and state‐of‐the‐art review that provides insight into their design principle and biological performances will be urgently required yet missing. In this review, the latest progress of these adaptive interfacial materials and implants for visual restoration will be summarized, and their challenges and opportunities for clinical use will be further discussed.
