Цель состояла в разработке унифицированного метода лечения катаракты и прогрессирующего кератоконуса I‑II степени.</p></sec><sec><title>Пациенты и методы</title><p>Пациенты и методы: В исследовании участвовало 4 пациента (5 глаз) с катарактой различной степени зрелости и плотности ядра в сочетании с прогрессирующим кератоконусом I‑II стадии. Средний возраст пациентов составил 42 года, средняя некоррегированная острата зрения (НОЗ) — 0,1, средняя коррегированная острота зрения (КОЗ) — 0,4. Хирургическое вмешательство проводили в две стадии. На первой — процедура, заключающаяся в формировании роговичных тоннелей при помощи фемтолазера с последующей факоэмульсификацией катаракты и имплантацией монофокальной асферической ИОЛ без торического компонента. На втором этапе, который проходил в среднем через 1‑2 недели, на основе данных кератотопограммы осуществляли имплантацию роговичных сегментов (ИРС) с последующим проведением кросслинкинга. Суть метода заключается в предварительном создании роговичных тоннелей с одномоментным проведением ФЭК и имплантацией монофокальной, неторической ИОЛ (рефракция цели — миопия 2,0‑3,0 диоптрии) с последующим проведением ИРС после стабилизации кератотопограммы (в среднем 1‑2 недели) и кросслинкинга. Второй этап позволяет не только стабилизировать развитие кератоконуса, но и провести докоррекцию до запланированной послеоперационной рефракции с коррекцией роговичного астигматизма. Имплантируемая монофокальная ИОЛ с нулевой или отрицательной асферикой не осложняет дальнейшее возможное хирургическое лечение кератоконуса (сквозную или глубокую послойную кератопластику) в случае его прогрессирования в будущем. Результаты: В 60 % случаев НОЗ составила 0,6 и выше, а конечная КОЗ в 80 % — 0,8‑1,0. Ни во время операции, ни в течение последующих 2 лет мы не наблюдали каких‑либо осложнений.</p></sec><sec><title>Заключение</title><p>Заключение: Комбинация факоэмульсификации катаракты с предварительным формированием роговичных тоннелей и последующей ИРС с проведением кросслинкинга у пациентов с катарактой и прогрессирующим кератоконусом I‑II стадии является безопасной, обладает хорошим прогнозируемым результатом и позволяет существенно сократить период реабилитации пациентов. Имплантация роговичных сегментов в сочетании с кросслинкингомспособствует стабилизации или уменьшению прогрессирования кератоконуса, что в конечном итоге позволяет отсрочить кератопластику либо полностью от нее отказаться.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose: To develop an uniform method of the treatment for patients with progressive keratoconus (stage 1‑2) and cataract. </p></sec><sec><title>Patients and methods</title><p>Patients and methods: 4 patients (5 eyes) with cataract and progressive keratoconus stage 1‑2 were enrolled in the study. Mean age was 42 years. In all patients, standard ophthalmic examination as well corneal topography, anterior segment optical coherence tomography, biometry, and IOL power calculations using IOLMaster were performed. Mean uncorrected visual acuity (UCVA) was 0.1 while mean best-corrected visual acuity (BCVA) was 0.4. Surgical technique included two steps. The first step was the creation of corneal tunnels with femtosecond laser with subsequent phaco and monofocal aspheric IOL implantation. The second step (1‑2 weeks later) was the implantation of intrastromal ring segments based on corneal topography and corneal crosslinking.</p></sec><sec><title>Results</title><p>Results: After the first step, all patients had myopic refraction (from –1.0 D to –2.5 D). Cylindrical component was almost unchanged. After the second step, the patients reported the vision improvement, mainly due to UCVA. Both spherical (myopic) and cylindrical components decreased, mainly due to the steep meridian. After the treatment, optical power of the cornea decreased, mainly due to the steep meridian. UCVA was 0.6 or more in 60 % of cases, final BCVA was 0.8‑1.0 in 80 % of cases. Neither intraoperative nor postoperative (follow-up was 2 years) complications were observed.</p></sec><sec><title>Conclusions</title><p>Conclusions: Combined phaco and prior creation of corneal tunnels with subsequent intrastromal ring segment implantation and crosslinking in patients with cataract and progressive keratoconus stage 1‑2 is safe, provides good predictable outcome and significantly reduces rehabilitation period.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>роговица</kwd><kwd>катаракта</kwd><kwd>кератоконус</kwd><kwd>стромальные сегменты</kwd><kwd>корнеальные сегменты</kwd><kwd>интраокулярные линзы</kwd><kwd>кросслинкинг</kwd><kwd>факоэмульсификация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cornea</kwd><kwd>cataract</kwd><kwd>keratoconus</kwd><kwd>stromal segments</kwd><kwd>corneal segments</kwd><kwd>intraocular lenses</kwd><kwd>crosslinking</kwd><kwd>phacoemulsification.</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">Krumeich J.
