Relevance. Despite the high level of cataract surgery, in some cases complications arise that lead to a decrease in visual functions, an increase in the duration of inpatient treatment and additional economic costs. Analysis of the results of cataract phacoemulsification helps to increase the effectiveness of predicting complications and their prevention. Aim. Analysis of intraoperative and early postoperative complications in cataract surgery for 2021–2022, conducted on the basis of the 2nd ophthalmological department of the State Budgetary Institution “N.A. Semashko Regional Clinical Hospital” Ryazan, Russia. Material and methods. Retrospective analysis of 66 case histories of patients who had complications in the intra- and postoperative period of cataract surgery. Results. Intraoperative complications included: posterior capsule opening (22 cases), dislocation of lens masses into the vitreal cavity (10 cases), hemorrhagic ciliochoroidal detachment (4 cases), expulsive hemorrhage (2 cases), hyphema (2 cases). In the postoperative period, the following complications were detected: hyphema – 2, hemophthalmos-4, ciliochoroidal detachment – 5, dislocation of intraocular lens (IOL) – 5, retained lenticular material in the anterior chamber – 4, exudative reaction – 12, keratopathy – 6, pupillary block – 1, endophthalmitis – 1. Conclusion. The improvement of the phacoemulsification technique together with the preoperative preparation of patients with cataracts made it possible to achieve a low level of intra- and postoperative complications (1.16% in 2021 and 0.89% in 2022, respectively, of all operated patients with cataracts). However, after analyzing the nature of complications, we identified a number of patterns: among intraoperative complications, the most common is the opening of the posterior capsule of the lens (0,29%), among postoperative – an exudative reaction (0,16%).
