However, these studies are practically absent in the practice of domestic ophthalmology.</p> <p><bold><italic>AIM: </italic></bold>To comparatively assess the clinical results of ISBCS and DSBCS.</p> <p><bold><italic>METHODS:</italic></bold> Our observation revealed that 1000 patients (2000 eyes) with binocular cataracts aged 37–68 years (mean age: 56.9±1.3 years), including 82% of males and 18% of females. Patients were divided into two groups: the main group (500 patients, 1000 eyes), who underwent ISBCS according to the developed modified algorithm (ma ISBCS), and the control group (500 patients, 1000 eyes), who underwent DSBCS technology with a break after the first surgical intervention 7–10 days. The study was conducted from January 2017 to September 2021. All patients were operated on by one surgeon. The following monofocal intraocular lenses (IOLs) were implanted to correct aphakia: Acrysof Natural IQ (Alcon, USA), Akreos AO (Bausch &amp; Lomb, USA), and Biflex (Medicontur, Hungary). Biometrics and IOL calculation were performed using an optical biometer IOL Master (Zeiss, Germany). The following clinical efficacy criteria were assessed (before and 3 months postoperatively): the presence of intra- and postoperative complications, measurement of the maximum correctable distance visual acuity (BCVA), and deviation from the target (±0.5 D) refraction.</p> <p><bold><italic>RESULTS:</italic></bold> maISBCS provides almost identical (with DSBCS) clinical results of surgical intervention, which is confirmed by the minimum (0.1%–0.6%, <italic>n</italic>=1000) level of postoperative complications (in the absence of endophthalmitis), the average values of BCVA (0.94±0.02; 0.95±0.02, <italic>p</italic>=0.724) and «target» refraction (0.30±0.05; 0.28±0.04, <italic>p</italic>=0.723), achieving BCVA of 1.0 rel unit (87%–88% of cases), and emmetropic refraction (28%–29% of cases).</p> <p><bold><italic>CONCLUSION:</italic></bold> maISBCS is a promising direction in cataract surgery, especially considering the established (compared to DSBCS) advantages associated with higher efficiency in terms of anisometropia development and the priority of performing in a difficult epidemiological environment, as well as a significant reduction in the financial costs of surgery.</p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Обоснование.</italic></bold> В последнее десятилетие появляется всё больше рандомизированных контролируемых исследований, указывающих на безопасность и эффективность немедленной последовательной двусторонней хирургии катаракты (НПДХК), сопоставимых с результатами проведения отсроченной последовательной двусторонней хирургии катаракты (ОПДХК). Однако в практике отечественной офтальмологии указанные исследования практически отсутствуют.</p> <p><bold><italic>Цель</italic></bold> — оценить клинические результаты НПДХК и ОПДХК.</p> <p><bold><italic>Материал и методы.</italic></bold> Под нашим наблюдением находились 1000 пациентов (2000 глаз) с бинокулярной катарактой в возрасте от 37 до 68 лет (средний возраст 56,9±1,3 года), из них мужчин — 82%, женщин — 18%. Пациентов разделили на 2 группы: основную (<italic>n</italic>=500, 1000 глаз), которым выполнялась НПДХК по разработанному модифицированному алгоритму (маНПДХК), и контрольную (<italic>n</italic>=500 пациентов, 1000 глаз), которых оперировали по технологии ОПДХК с перерывом после 1-го оперативного вмешательства в 7–10 дней. Исследование проводили в период с января 2017 по сентябрь 2021 года. Все пациенты прооперированы одним хирургом. В целях коррекции афакии имплантировали следующие монофокальные интраокулярные линзы (ИОЛ): «Acrysof Natural IQ» (Alcon, США), «Akreos AO» (Bausch &amp; Lomb, США), «Biflex» (Medicontur, Венгрия). Биометрия и расчёт ИОЛ выполнены при помощи оптического биометра «IOL Master» (Carl Zeiss, Германия). Использовали следующие критерии клинической эффективности (до и спустя 3 мес после операции): наличие интра- и послеоперационных осложнений, измерение максимально корригируемой остроты зрения вдаль (МКОЗ) и отклонение от целевой (±0,5 дптр.) рефракции.</p> <p><bold><italic>Результаты.</italic></bold> Проведение маНПДХК обеспечивает практически идентичные с ОПДХК клинические результаты оперативного вмешательства, что подтверждается минимальным (0,1–0,6%, <italic>n</italic>=1000) уровнем послеоперационных осложнений (при отсутствии эндофтальмита), средними величинами МКОЗ (0,94±0,02, 0,95±0,02; <italic>р</italic>=0,724) и рефракции «цели» (0,30±0,05, 0,28±0,04; <italic>р</italic>=0,723), а также достижением МКОЗ =1,0 отн. ед. (87–88% случаев) и эмметропической рефракции (28–29% случаев).</p> <p><bold><italic>Заключение.</italic></bold> маНПДХК можно считать перспективным направлением катарактальной хирургии, в особенности с учётом установленных (по сравнению с ОПДХК) преимуществ, связанных с более высокой эффективностью с позиции развития анизометропии, с приоритетностью проведения в сложной эпидемиологической обстановке, а также существенным уменьшением финансовых затрат на оперативное вмешательство.</p></trans-abstract><kwd-group xml:lang="en"><kwd>cataract removal</kwd><kwd>endophthalmitis</kwd><kwd>visual acuity</kwd><kwd>ocular refraction</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>удаление катаракты</kwd><kwd>эндофтальмит</kwd><kwd>острота зрения</kwd><kwd>рефракция глаза</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Grzybowski A, Wasinska-Borowiec W, Claoué C.
