视网膜假体有可能恢复盲人一定程度的视觉功能。虽然用于视神经和视皮层的视觉假体装置也具有潜在的应用，但视网膜方法提供了在眼睛后部相对可接近的视网膜神经元的优点。生物学研究已经证明了植入和刺激的生物相容性，并研究了视网膜对刺激的反应。最近的临床试验表明，一种原型视网膜前植入物，尽管接触视网膜的电极很少，但仍然允许测试对象执行简单的视觉任务。正在进行的工程研究集中在高分辨率植入物的制造上
Retinal prostheses have the potential to restore some level of visual function to blind individuals. While visual prosthetic devices for the optic nerve and visual cortex also have potential application, the retinal approach offers the advantage of relatively accessible retinal neurons in the back of the eye. Biological studies have demonstrated biocompatibility of implantation and stimulation and have investigated retinal response to stimulation. Recent clinical trials have shown that a prototype epiretinal implant, despite having few electrodes contacting the retina, still allows test subjects to perform simple visual tasks. Ongoing engineering research is focusing on the fabrication of a high-resolution implant
