Abstract

Phacoemulsification (PE) is the leading method of cataract surgery. Purpose. To assess the impact of PE on corneal subbasal nerve plexus in patients with pseudoexfoliation syndrome (PEX) using confocal in vivo microscopy. Methods. 42 patients (42 eyes) were enrolled in the study. The main group consisted of 24 patients (24 eyes) with PEX syndrome, and 18 patients (18 eyes) without it composed the control group. Confocal in vivo microscopy was performed before and after PHACO. Results. In patients with PEX after PE, an increase in number of nerve branches and pellet-like structures in them were noticed (p < 0,05).
