PURPOSE To investigate the integration of subretinal implants containing full-depth perforations of various widths with rat and pig retina across weeks of implantation. METHODS In transgenic P23H rhodopsin line 1 (TgP23H-1) rats and wild-type (WT) pigs, we examined four subretinal implant designs: solid inactive polymer arrays (IPA), IPAs with 5- or 10-μm wide perforations, and active bipolar...
