Однако не решен вопрос по использованию данного метода у пациентов с анатомически измененной роговицей при кератоконусе.</p><sec><title>Цель</title><p>Цель: оценить эффективность и безопасность коррекции миопии высокой степени в сочетании с миопическим астигматизмом методом имплантации факичных интраокулярных линз у пациентов со стабилизированным кератоконусом 1–2-й стадии.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование включены результаты 27 операций по имплантации факичных интраокулярных линз у пациентов с миопией высокой степени и миопическим астигматизмом (–12,63 ± 4,25 дптр) с тонкой роговицей и сопутствующим диагнозом «кератоконус 1–2-й стадии» (после проведенного лечения методом кросслинкинга роговичного коллагена) – основная группа. Контрольная группа (результаты 35 операций) – пациенты с субклиническим непрогрессирующим кератоконусом (Form Fruste). Всем исследовали динамику остроты зрения, стабильность рефракции по сферическому и цилиндрическому компоненту до и на 1-й день после операции, а также через 1, 6 и 12 месяцев после имплантации. Также проводили исследование внутриглазного давления, гониоскопию, ультразвуковую эхобиометрию и ультразвуковое офтальмосканирование, биомикроскопию, офтальмоскопию, эндотелиальную микроскопию, определение характера зрения и стереозрения, ультразвуковую биомикроскопию, переднюю оптическую когерентную томографию, электрофизиологические исследования, статистический анализ. Имплантирована факичная интраокулярная линза IPCL, изготовленная из гидрофильного акрила. Эта линза позволяет корригировать миопию до 30 дптр и астигматизм до 10 дптр.</p></sec><sec><title>Результаты</title><p>Результаты. У всех пациентов была получена высокая некорригированная острота зрения 0,86 ± 0,11. Коррекция астигматизма достигнута в 96 % случаев. Среднее значение послеоперационного свода (Vault) – расстояние от задней поверхности факичных интраокулярных линз до передней капсулы хрусталика – 527,5 ± 40,27 мкм (диапазон 460–600 мкм), внутриглазное давление – 11,7 ± 2,08 мм рт. ст. Отмечено недостоверное снижение количества эндотелиальных клеток роговицы с 2599 ± 157,3 до 2375 ± 125,3 кл/мм2 в первой и с 2614 ± 104,8 до 2375 ± 43,3 кл/мм2 во второй группе соответственно (p &gt; 0,05), что не превышает допустимых значений потери 4–7 % от дооперационных значений в обеих группах. За период наблюдения не было случаев развития катаракты, пигментной глаукомы, зрачкового блока и других угрожающих зрению осложнений.</p></sec><sec><title>Выводы</title><p>Выводы. Имплантация факичных интраокулярных линз у пациентов со стабилизированным кератоконусом на ранних стадиях и субклиническим непрогрессирующим кератоконусом позволяет эффективно и практически безопасно корригировать высокую степень миопии и астигматизма.</p></sec></abstract><trans-abstract xml:lang="en"><p>To date, extensive experience has been accumulated in the correction of high myopia and myopic astigmatism through the implantation of additional negative lenses (phakic intraocular lenses). However, the use of this method in patients with anatomically altered corneas due to keratoconus remains unresolved.</p><sec><title>Purpose</title><p>Purpose: to assess the effectiveness and safety of correcting high myopia combined with myopic astigmatism by implanting phakic intraocular lenses in patients with stabilized keratoconus at stages 1–2.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study encompassed results from 27 surgeries involving the implantation of phakic intraocular lenses in patients with high myopia and myopic astigmatism (12.63 ± 4.25 D). These patients had thin corneas and were diagnosed with stage 1–2 keratoconus after undergoing corneal collagen crosslinking treatment – this constituted the main group. The control group comprised 35 surgeries performed on patients with subclinical non-progressive keratoconus (Forme Fruste). All participants underwent evaluations for visual acuity dynamics and refractive stability of spherical and cylindrical components before surgery, immediately post-surgery, and then at 1, 6, and 12 months after implantation. Additional assessments included intraocular pressure measurements, gonioscopy, ultrasonic echobiometry, ultrasonic ophthalmoscopy, biomicroscopy, ophthalmoscopy, endothelial microscopy, vision character and stereopsis determination, ultrasound biomicroscopy, anterior segment optical coherence tomography, electrophysiological studies, and statistical analysis. An IPCL (a type of phakic intraocular lenses made from hydrophilic acrylic) was implanted, capable of correcting myopia up to 30 D and astigmatism up to 10 D.</p></sec><sec><title>Results</title><p>Results. All patients achieved high uncorrected visual acuity 0.86 ± 0.11. Astigmatism correction was successful in 96% of cases. The average postoperative vault – the distance from the back surface of the phakic intraocular lenses to the anterior lens capsule – was 527.5 ± 40.27 μm (range 460–600 μm), and the intraocular pressure was 11.7 ± 2.08 mm Hg. There was a minor decrease in corneal endothelial cell count from 2599 ± 157.3 to 2375 ± 125.3 cells/mm² in the first group and from 2614 ± 104.8 to 2375 ± 43.3 cells/mm² in the second group respectively (p &gt; 0.05), which falls within the acceptable loss range of 4–7% from preoperative values for both groups. Throughout the observation period, there were no cases of cataract development, pigmentary glaucoma, pupillary block, or other vision-threatening complications.</p></sec><sec><title>Conclusions</title><p>Conclusions. Implantation of phakic intraocular lenses in patients with early-stage stabilized keratoconus and subclinical non-progressive keratoconus provides an effective and practically safe means of correcting high myopia and astigmatism.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>кератоконус</kwd><kwd>коррекция кератоконуса</kwd><kwd>факичные интраокулярные линзы</kwd><kwd>роговичная миопия</kwd><kwd>астигматизм</kwd></kwd-group><kwd-group xml:lang="en"><kwd>keratoconus</kwd><kwd>keratoconus correction</kwd><kwd>phakic intraocular lenses</kwd><kwd>corneal myopia</kwd><kwd>astigmatism</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">авторы не получали финансирование при проведении исследования и написании статьи</funding-statement><funding-statement xml:lang="en">the authors received no specific funding for this work</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Vinciguerra P, Albe E, Trazza S, Seiler T, Epstein D.
