The patients were divided into 2 groups (125 eyes in each group). In all patients, the type of overmature cataract was determined intraoperatively using I-OCT integrated into the operating microscope [Hi-R NEO (HAAG STREIT, Germany)]. In the first group, femto-support for cataract surgery was performed according to a developed algorithm with optimized parameters of femtolaser exposure depending on the type of overmature cataract according to I-OCT data, in the second group, femto-support was performed using a standard method. When using the developed algorithm with optimized parameters of femtolaser exposure in comparison with femtoassistance, performed according to the standard method, the frequency of incomplete femtocapsulotomy at 2 (2.5 % vs 17.4 %, respectively) and 3 (4.9 % vs 21.6 %, respectively)) types of overmature cataract according to I-OCT data, as well as the frequency of capsulorhexis escape in type 3 (2.4 % vs 16.2 %, respectively) were statistically significantly lower in the first group of patients. The developed algorithm with optimized parameters of femtolaser exposure at the stage of anterior capsulorhexis, taking into account the type of overripe cataract according to intraoperative OCT data, ensures high quality of this stage of surgery and expands the possibilities of practical application of femtolaser support for cataract surgery in complicated cases.</p></abstract><trans-abstract xml:lang="ru"><p>В исследование вошли 196 пациентов (250 глаз) с перезрелой катарактой. Пациенты были разделены на 2 группы (по 125 глаз в каждой группе). Всем пациентам интраоперационно с помощью интегрированной в операционный микроскоп интраоперационной оптической когерентной томографии (И-ОКТ), Hi-R NEO (HAAG STREIT, Германия), определяли тип перезрелой катаракты. В первой группе проводили фемтосопровождение хирургии катаракты по разработанному алгоритму с оптимизированными параметрами фемтолазерного воздействия в зависимости от типа перезрелой катаракты по данным И-ОКТ, во второй – фемтосопровождение по стандартной методике. При использовании разработанного алгоритма с оптимизированными параметрами фемтолазерного воздействия по сравнению с фемтосопровождением, выполняемым по стандартной методике, частота получения неполной фемтокапсулотомии при 2-м (2,5 % vs 17,4% соответственно) и 3-м (4,9 % vs 21,6 % соответственно) типах перезрелой катаракты по данным И-ОКТ, а также частота убегания капсулорексиса при 3-м типе (2,4 % vs 16,2 % соответственно) были статистически достоверно меньше в первой группе пациентов.Разработанный алгоритм с оптимизированными параметрами фемтолазерного воздействия на этапе переднего капсулорексиса с учетом типа перезрелой катаракты по данным И-ОКТ обеспечивает высокое качество данного этапа хирургии и расширяет возможности практического применения фемтолазерного сопровождения хирургии катаракты в осложненных случаях.</p></trans-abstract><kwd-group xml:lang="en"><kwd>overmature cataract</kwd><kwd>femtolaser capsulorhexis</kwd><kwd>intraoperative optical coherence tomography</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>перезрелая катаракта</kwd><kwd>фемтолазерный капсулорексис</kwd><kwd>интраоперационная оптическая когерентная томография</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Chee S.P., Chan N.S.W., Yang Y., Ti S.E.
