Advanced Atrophic Dry Age-related Macular Degeneration (dry-AMD)


PRIMA bionic vision system, including a totally wireless implantable photovoltaic sub-retinal microchip, is designed to elicit useful functional prosthetic vision. Click here for more information about the PRIMA system.

Website : identifier

NCT 03392324 : PRIMA US-Feasibility Study in Atrophic Dry AMD - Age Related Macular Degeneration (PRIMA-FS-US)

What results are expected?

This is a clinical research study. In a similar feasibility study in France, 5 patients have already been successfully implanted, with positive interim 6 months follow-up results announced by the company in early January, 2019. Interim results to date and simulations demonstrate that the PRIMA bionic vision system can successfully elicit useful functional visual perception from the previously degenerated central atrophic retina, exclusive of residual natural peripheral perception. Subsequent training and reeducation enabled implanted patients to identify visual patterns including numbers and letters.

The achieved prosthetic visual acuity to date is the highest among those published from current prosthetic vision technologies.
