Prior to the implant, eyes were treated with an anti-VEGF therapy, dexamethasone implant, or focal or panretinal photocoagulation. Effectiveness outcomes included changes in visual acuity and macular edema. Safety outcomes included intraocular pressure (IOP) changes, IOP drugs, and IOP-related surgeries/interventions. Treatment burden was assessed by comparing the number of DME treatments before and after FAc implantation.Results: The FAc implant reduced macular volume in 16/18 (89%) eyes, with a statistically significant mean change of –1.33 mm3 (p=0.001). The average central retinal thickness reduction for all 18 eyes was statistically significant, decreasing from 444 μm at baseline to 359 μm after the FAc implant (p |
