In this study, AuTNA I (nanoparticle-decorated TiO2 Nanowire Arrays), which is designed to replace the damaged photoreceptors in RP patients, was implanted in one eye of the subjects. The change or improvement in the visual acuity of the subjects, as well as the potential side effects, was then fully evaluated.
The objective of the study is to evaluate:~Safety of AuTNA I for subretinal implantation in patients with retinitis pigmentosa;~Efficacy of AuTNA I for subretinal implantation in patients with retinitis pigmentosa.
