CHANGES AND DYNAMICS OF INTRAOPERATIVE AND POSTOPERATIVE COMPLICATIONS AFTER APPLYING VARIOUS TECHNIQUES OF SURGICAL TREATMENT OF CATARACT

Abstract

Transition to the small incision surgery and the practice of cataract phacoemulsification and femtosecond-guided cataract phacoemulsification have contributed to the reduction of postoperative complications, however, despite this, there are some potentially dangerous sight problems that include infective endophthalmitis, toxic syndrome of the eye anterior segment, intraoperative suprachoroidoid hemorrhage, cystic macular edema, retinal detachment, persistent corneal edema and IOL dislocation. According to the study conducted in the UK, the overall frequency of complications following phacoemulsification was 8.7%. Complications that arise at any stage of the surgical intervention and after it have a negative impact on the immediate and remote functional outcomes of the treatment. Thus, the improvement of surgical treatment of age-related cataracts by studying the features and mechanisms of the development of postoperative edema in the central retinal zone, as well as the development of new methods for predicting this complication, is an urgent problem of ophthalmology. The aim of this study was to determine and differentiate the frequency and dynamics of intraoperative, early and late post-operative complications in various techniques of surgical treatment of age-related cataracts. Materials and methods. 558 patients (558 eyes) with cataracts participated in the examination and treatment. The first group consisted of 298 patients (298 eyes) who underwent standard phacoemulsification, and the second group involved 260 patients (260 eyes) who were performed on femtosecond-guided cataract phacoemulsification. The examination was carried out on the 1 day, and in 1, 3 6 and 12 months after cataract surgery. The use of femtosecond laser can reduce the rate of intraoperative, as well as early and late post-operative complications after the cataract removal.
