Пациенты и методы. Проведен ретроспективный анализ результатов лечения 27 пациентов (27 глаз) с прогрессирующим кератоконусом I–II стадий по классификации Amsler — Krumeich, которым с 2012 по 2014 год был проведен трансэпителиальный кросслинкинг роговицы. На основании объективных клинических исследований была оценена эффективность лечения и течение процесса. У части пациентов с прогрессирующим течением заболевания после трансэпителиального кросслинкинга была выполнена процедура повторного УФ-кросслинкинга роговицы по стандартному протоколу. Результаты. Установлено, что после трансэпителиального кросслинкинга в течение 24 месяцев в 12 глазах (44 %) отмечалось прогрессирование заболевания, выражающееся в увеличении преломляющей силы роговицы на 0,95 ± 0,18 дптр, уменьшении толщины роговицы в среднем с 484 ± 156 до 446 ± 87 мкм. Был выполнен повторный кросслинкинг, через 6 месяцев положительная динамика отмечалась в 10 случаях (83,3 %), острота зрения достигла дооперационного уровня, преломляющая сила роговицы — 50,32 ± 0,84 дптр. Отмечена стабилизация процесса во всех 12 глазах, снижение среднего показателя преломляющей силы роговицы в среднем на 1,1 ± 1,25 дптр, роговичного астигматизма — на 1,2 ± 0,31 дптр, толщины роговицы до 427 ± 38,7 мкм. Выводы. Применение модифицированных протоколов кросслинкинга, в частности трансэпителиального кросслинкинга с ионофорезом, имеет более низкую эффективность, обеспечивая стабилизацию в 56 % случаев относительно стандартного, что необходимо учитывать при выборе клинического подхода и отборе пациентов. Выполнение повторного кросслинкинга по стандартному протоколу показало высокую эффективность и безопасность процедуры в 100 % случаев, однако данный подход должен быть изучен на большем количестве наблюдений.</p></abstract><trans-abstract xml:lang="en"><p>The purpose is to study the efficacy and safety of repeated UV corneal crosslinking in patients with advanced keratoconus after transepithelial crosslinking performed previously. Patients and methods. A retrospective analysis of the treatment results of 52 patients (52 eyes) with progressive keratoconus stage I-II according to the Amsler — Krumeich classification, which from 2012 to 2014 were treated by transepithelial corneal crosslinking. Based on objective clinical studies, the effectiveness of the treatment and the course of the process were evaluated. In some patients with a progressive course of the process (12 eyes), after the transepithelial crosslinking, a procedure of repeated UV crosslinking of the cornea was performed according to a standard protocol. Results. After transepithelial cross-linking within 24 months in 12 eyes (44 %) progression of the disease was observed, manifested by an increase in the refractive power of the cornea by 0.95 ± 0.18 D, a decrease in the thickness of the cornea from 484 ± 156 to 446 ± 87 microns. Repeated cross-linking was performed and after 6 months and positive dynamics was observed in 10 cases (83.3 %), visual acuity reached the preoperative level, the refractive power of the cornea was 50.3 ± 0.84 D. Stabilization of the process was noted in all 12 eyes, a decrease in the average refractive index of the cornea by an average of 1.1 ± 1.25 D, corneal astigmatism — by 1.2 ± 0.31 D, the cornea thickness to 427 ± 38.7 mc.Conclusion. The use of modified crosslinking protocols, in particular transepithelial with iontophoresis, has a lower efficiency, showing stabilization in 56 % of cases, compared to the standard, which must be considered when choosing a clinical approach and selecting patients. Performing recrosslinking using a standard protocol showed high efficiency and safety of the procedure in 100 % of cases, however, this approach should be studied on a larger number of observations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>роговица</kwd><kwd>кератоконус</kwd><kwd>кросслинкинг</kwd><kwd>кератэктазии</kwd><kwd>УФ-облучение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cornea</kwd><kwd>keratoconus</kwd><kwd>crosslinking</kwd><kwd>keratectasia</kwd><kwd>UV irradiation</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">Бикбов М.М., Бикбова Г.М.
