Brief Summary:
The study objective is to demonstrate safety of the NR 600 System, and to evaluate the performance of the device in restoring visual activity of daily living in subjects with retinal degenerative diseases and severe visual impairment

Condition or disease Intervention/treatment Phase
Retinitis Pigmentosa Retinal Degeneration Device: Retinal surgery with implantation of epi-retinal device Not Applicable

Detailed Description:
The NR600 is a retinal prosthetic system intended to provide electrical stimulation to the retina to induce visual perception in patients with severe to profound vision loss due to degenerative retinal disease. The system is consisting of an autonomous epiretinal implant with penetrating electrodes, Glasses and a Clinician Station. The implant is Infrared (IR) powered and is designed to convert visual input into well-defined electrical stimulation patterns suited to elicit neuronal retina activity. All study subjects will be implanted with the device in one eye and will be followed for 18-months.
