Пациенты и методы. Проведен ретроспективный анализ результатов лечения 11 пациентов (12 глаз) с прогрессирующим кератоконусом I–III стадий (возраст 27 ± 6 лет). Исходная максимально корригированная острота зрения составляла 0,65 ± 0,11, средняя преломляющая сила роговицы — 53,1 ± 2,42 дптр, минимальная толщина стромы — 459 ± 19,6 мкм. Хирургическое лечение заключалось в проведении персонализированного кросслинкинга: после локальной деэпителизации вершины конуса и фотосенсибилизации 0,1 % раствором рибофлавина с последующим УФ-облучением (6 мВт/см2) в течение 15 минут. Послеоперационное ведение включало стандартную антибактериальную, противовоспалительную и длительную кератопротекторную терапию. Результаты. Данная когорта пациентов полностью удовлетворяла требованиям для проведения повторного кросслинкинга по протоколу УЛ-КРК, оценка состояния роговицы осуществлялась через 6, 12, 18 и 36 месяцев после выполнения процедуры акселирированного локального кросслинкинга. НКОЗ повысилась с 0,32 ± 0,19 до 0,55 ± 0,15 уже к 6 месяцу наблюдения и оставалась стабильной на протяжении всего исследования, МКОЗ значимо не менялась (0,66 ± 0,16). По данным прибора Pentacam HR (Oculus, Германия) Kmax снизился с 53,1 ± 2,42 до 51,9 ± 1,09 дптр, а цилиндрический компонент (Cyl) уменьшился с –2,89 ± 1,02 до –1,95 ± 0,77 дптр. Формирование демаркационной линии визуализировалось на глубине 270–330 мкм в первые 3 месяца по данным оптической когерентной томографии роговицы (оптический когерентный томограф — Solix (Optovue Inc., США)). Показатели плотности эндотелиальных клеток (ПЭК) оставались стабильными на протяжении всего срока наблюдения (2327 ± 121 кл/мм2) (эндотелиальный микроскоп «Topcon SP-1P»). Заключение. Повторный кросслинкинг является эффективным и безопасным методом стабилизации прогрессирующего кератоконуса, обеспечивающим долгосрочный рефракционный эффект и сохранение морфофункциональных параметров роговицы.</p></abstract><trans-abstract xml:lang="en"><p>Study objective: To analyze the clinical, functional, and safety efficacy of accelerated local corneal collagen crosslinking (ALCCL) in patients with progressive keratoconus who had previously undergone crosslinking. Patients and methods. A retrospective analysis of treatment outcomes was performed in 11 patients (12 eyes) with progressive keratoconus stages I–III (age 27 ± 6 years). The initial best-corrected visual acuity was 0.65 ± 0.11, the mean corneal refractive power was 53.1 ± 2.42 D, and the minimum stromal thickness was 459 ± 19.6 µm. Surgical treatment consisted of personalized crosslinking: local de-epithelialization of the cone apex and photosensitization with a 0.1% riboflavin solution, followed by UV irradiation (6 mW/cm2) for 15 minutes. Postoperative care included standard antibacterial, anti-inflammatory, and long-term keratoprotective therapy. Results. This cohort of patients fully met the requirements for repeat crosslinking according to the UL-KRK protocol. Corneal condition was assessed at 6, 12, 18, and 36 months after the accelerated local crosslinking procedure. The uncorrected visual acuity (UCVA) increased from 0.32 ± 0.19 to 0.55 ± 0.15 by the 6-month follow-up and remained stable throughout the study. The BCVA did not change significantly (0.66 ± 0.16). According to the Pentacam HR device (Oculus, Germany), Kmax decreased from 53.1 ± 2.42 to 51.9 ± 1.09 D, and the cylindrical component (Cyl) decreased from –2.89 ± 1.02 to –1.95 ± 0.77 D. The formation of the demarcation line was visualized at a depth of 270–330 µm in the first 3 months according to corneal optical coherence tomography (optical coherence tomograph — Solix (Optovue Inc., USA)). Endothelial cell density (ECD) remained stable throughout the entire observation period (2327 ± 121 cells / mm2) (endothelial microscope Topcon SP-1P). Conclusion. Repeated crosslinking is an effective and safe method for stabilizing progressive keratoconus, providing a long-term refractive effect and preserving the morphofunctional parameters of the cornea.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кератоконус</kwd><kwd>повторный кросслинкинг роговичного коллагена</kwd><kwd>рибофлавин</kwd><kwd>демаркационная линия</kwd><kwd>кератэктазия</kwd><kwd>УФ-облучение</kwd><kwd>фотосенсибилизация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>keratoconus</kwd><kwd>repeated corneal collagen crosslinking</kwd><kwd>riboflavin</kwd><kwd>demarcation line</kwd><kwd>keratectasia</kwd><kwd>UV irradiation</kwd><kwd>photosensitivity</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Слонимский АЮ.
