Restoration of sight in geographic atrophy using a photovoltaic subretinal prosthesis

OBJECTIVE: To evaluate feasibility of restoration of central vision in patients with age-related macular degeneration using a wireless photovoltaic subretinal implant. In particular, to assess safety of sub-retinal implantation and quality of prosthetic vision in patients with geographic atrophy. CONCLUSIONS: Wireless chip PRIMA can be safely implanted under the atrophic macula in patients with geographic
