人工视觉的研究是指在视路的不同部位植入不同的视觉假体 ,由植入物假体产生电信号 ,刺激并激活视觉系统 ,从而使失明或频于失明的眼重新获得部分有用视力。本文就近年来研究最为活跃的视网膜假体的实验基础、种类、植入方法、生物相容性及长期稳定性、优缺点等作一介绍。 Artificial vision refers to implanting different visual prostheses in different parts of the visual pathway, generating electrical signals from implant prostheses, stimulating and activating the visual system so that blind or frequently-blind eyes regain some useful visual acuity . In this paper, in recent years, the most active retinal prosthesis experimental basis, type, implantation method, biocompatibility and long-term stability, advantages and disadvantages were introduced.
