The Vision Restoration Systems (VRS) being developed by Pixium Vision in Paris are aimed at restoring sight to blind patients with a working optic nerve.

VRS technology uses a retinal implant, a camera mounted on glasses, and a portable processor together to conduct the captured visual information to the implant.

The epi-retinal IRIS system is being studied in European clinical trials while the sub-retinal PRIMA system is at an earlier development stage, according to the company Web site.
