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 atrophy and restore central visual perception with acuity close to
the theoretical limit of the implant. Implantation did not reduce the natural
residual visual acuity of the patients. Implants with smaller pixels are being
developed.
