Argus™ II 60通道视网膜前膜假体的开发旨在为因外部视网膜退行性疾病而失明的受试者提供部分视力恢复。迄今为止，该器械已作为可行性研究的一部分植入21名受试者体内。在植入后6个月的门发现和线追踪定向和移动性测试中，受试者在系统打开与系统关闭时分别显示出86%和73%的改善。在使用触摸屏显示器的高对比度方形定位测试中，87%的受试者在系统开启时的表现明显优于关闭时。这些初步结果表明，Argus II系统为盲人提供了一些功能性视觉。
The Argus™ II 60 channel epiretinal prosthesis has been developed in order to provide partial restoration of vision to subjects blinded from outer retinal degenerative disease. To date the device has been implanted in 21 subjects as part of a feasibility study. In 6 month post-implantation door finding and line tracking orientation and mobility testing, subjects have shown improvements of 86% and 73%, respectively, for system on vs. system off. In high-contrast Square Localization tests using a touch screen monitor 87% of tested subjects performed significantly better with the system on compared with off. These preliminary results show that the Argus II system provides some functional vision to blind subjects.
