The aim of the study is to analyze the electrophysiological function of the retina (its cone system) near the macula, using multifocal electroretinogram in eyes with exudative age‑related macular degeneration which underwent cataract surgery. Material and methods. A 12‑month prospective, randomized study included 50 eyes of 49 patients (mean age 78.94 ± 5.54 years) with diagnosed inactive exudative age‑related macular degeneration and cataract, previously treated with intravitreal injections of vascular endothelial growth factor inhibitors. Two groups of patients were selected: group I (n = 25 eyes) – patients who underwent phacoemulsification and group II (n = 25 eyes) – patients who were observed. In both groups multifocal electrotertinogram recordings, like: response density, latency and amplitude of P1 wave were observed. Results. In both groups and between them, final results of average response density, average latency and average amplitude of P1 wave showed no differences in subsequent time intervals. (p>0.05) Conclusions. Phacoemulsification does not affect the retinal bioelectrical function in patients with inactive exudative macular degeneration.
