A retinal implant is a visual prosthesis for restoration of sight to patients blinded by retinal degeneration. The system is meant to partially restore useful vision to those who have lost their photoreceptors due to retinal diseases such as retinitis pigmentosa (RP) or age-related macular degeneration (AMD).
The device was approved with data from a single-arm clinical trial that enrolled thirty people with severe retinitis pigmentosa; the longest follow-up on a trial subject was 38.3 months. [4] People in the trial received the implant in only one eye and tests were conducted with the device switched on, or switched off as a control. [5]
Photovoltaic retinal prosthesis is a technology for restoration of sight to patients blinded by degenerative retinal diseases, such as retinitis pigmentosa and age-related macular degeneration (AMD), when patients lose the 'image capturing' photoreceptors, but neurons in the 'image-processing' inner retinal layers are relatively well-preserved.

This high-acuity implant would be inserted epiretinally. Patient tests were planned for this device in 2014 once preclinical testing had been completed, it is unknown whether these trials ever took place. Patients with retinitis pigmentosa were to be the first to participate in the studies, followed by age-related macular degeneration. Each ...
Retinitis Pigmentosa International (RPI or RP International) is an international, 501(c)(3) non-profit organization that is committed to focusing world attention on eye problems. RP International promotes research, public awareness, education, and human services for victims of degenerative eye diseases .
2012/2015 Electronic Retinal Implant Trials. These trials, funded by the NIHR and the Oxford (OUH) BRC, tested the ability of an electronic retina to replace a retina that has become damaged, a development common in patients with the hereditary condition retinitis pigmentosa (RP). The implants were developed by German company Retina Implant AG ...
