Исследование влияния факоэмульсификации возрастной катаракты на слезопродукцию и морфометрические параметры роговицы

Abstract

Purpose. To study the effect of phacoemulsification (PE) of age-related cataract (ARC) on tear production (TP) and morphometric parameters of the cornea. Material and methods. 120 patients (120 eyes) aged 62 to 83 years after ARC PE were examined. All patients were divided into 2 groups according to the level of TP: 1st group – 60 patients with normal and slightly reduced TP, 2nd group – 60 patients with moderate and severe suppression of TP. In addition to standard research methods, all patients underwent the Schirmer-1 test, OCT-scanning of the cornea, also tear break-up time (TBUT), endothelial cell density (ECD) (initially, the next day after surgery, then on the 10th, 20th and 30th days) were analyzed. Results. The indices of TBUT, corneal epithelium thickness (CEC), corneal stromal thickness (CST) and ECD in the eyes of patients of the second group were lower than in the eyes with normal TP. Conclusion. The analysis showed that in patients with a moderate and severe decrease in TP, postoperative changes in CEC occur 4 times more often, and CST – 1.5 times more often than in eyes with normal TP. At the final stage of treatment, the recovery of CEC in the eyes of patients in the second group of the study was observed 2.6 times less than in the eyes of patients in the first group, which may indicate the possible presence of neurotrophic disorders in the cornea in patients with reduced TP. Keywords: age-related cataract, phacoemulsification, tear production, corneal epithelium thickness, corneal stroma thickness
