После сквозной кератопластики (СКП) в каждом случае отмечен индуцированный роговичный астигматизм от лёгкой до высокой степени. Существующий выбор коррекции посткератопластического астигматизма направлен на поиск индивидуального подхода для того, чтобы скомпенсировать его и не ослабить при этом биомеханические свойства роговичного трансплантата.Цель исследования: анализ клинико-функциональных и морфологических результатов коррекции посткератопластического астигматизма методом имплантации интрастромальных роговичных сегментов (ИРС) с фемтосопровождением.Методы. Обследованы 22 пациента до и через 1 год после операции. Операция проводилась под местной анестезией в два этапа: I этап – формировали интрастромальный туннель с использованием фемтосекундного лазера «Фемто Визум» 1 МГц («Оптосистемы», Россия); II этап – имплантировали ИРС. Оценка результатов проводилась стандартными и специальными методами исследования с помощью оптической когерентной томографии Visante OCT (Zeiss, Германия), кератотопографии (Tomey-5, Япония), оптического анализатора роговицы ORA (Reichert, США), лазерной тиндалеметрии FС-2000 (Kowa, Япония) и конфокального микроскопа Confoscan-4 (Nidek, Япония).Результаты. До операции некорригированная острота зрения в среднем составила 0,09 ± 0,05, через 1 год – 0,50 ± 0,16; корригированная острота зрения – 0,30 ± 0,12 и 0,60 ± 0,05 соответственно; величина цилиндрического компонента рефракции – –10,29 ± 3,12 и –2,20 ± 0,64 дптр соответственно; среднее значение кератометрии – 43,59 ± 2,14 и 38,56 ± 1,75 дптр соответственно; корнеальный гистерезис – 7,92 ± 1,22 и 8,95 ± 1,05 мм рт. ст. соответственно; фактор резистентности роговицы – 7,01 ± 1,81 и 8,44 ± 1,44 мм рт. ст. соответственно; поток белка во влаге передней камеры – 2,97 ± 0,28 и 3,04 ± 0,24 ф/мс соответственно; плотность эндотелиальных клеток – 1521 ± 327 и 1475 ± 419 кл./мм2 соответственно.Заключение. Имплантация интрастромальных роговичных сегментов в роговичный трансплантат с применением фемтосекундного лазера является эффективным и безопасным методом при коррекции посткератопластического астигматизма.</p></abstract><trans-abstract xml:lang="en"><p>Background. After penetrating keratoplasty, mild to high induced corneal astigmatism was observed in each case. The existing choice of correction of postkeratoplastic astigmatism is aimed at fi nding an individual approach in order to compensate for it and not weaken the biomechanical properties of the corneal graft.The aim: to analyze the clinical, functional, and morphological results of postkeratoplastic astigmatism correction by implantation of intrastromal corneal segments using a femtosecond laser.Methods. 22 patients were examined before and 1 year after surgery. The operation was performed under local anesthesia: stage I – an intrastromal tunnel was formed using a femtosecond laser “Femto Visum” 1 MHz (Optosystems, Russia); stage II – the intrastromal corneal segments were implanted. The results were assessed using standard and special research methods using optical coherence tomography Visante OCT (Zeiss, Germany), keratotopography (Tomey-5, Japan), optical corneal analyzer ORA (Reichert, USA), laser tindalemetry FC-2000 (Kowa, Japan) and confocal microscope Confoscan-4 (Nidek, Japan).Results. Before the operation, uncorrected visual acuity averaged 0.09 ± 0.05, after a year – 0.50 ± 0.16; best corrected visual acuity – 0.30 ± 0.12 and 0.60 ± 0.05 respectively; cylindrical component of refraction – –10.29 ± 3.12 and –2.20 ± 0.64 D respectively; mean keratometry value – 43.59 ± 2.14 and 38.56 ± 1.75 D respectively; corneal hysteresis – 7.92 ± 1.22 and 8.95 ± 1.05 mm Hg respectively; corneal resistance factor – 7.01 ± 1.81 and 8.44 ± 1.44 mm Hg respectively; protein fl ux in the moisture of the anterior chamber – 2.97 ± 0.28 and 3.04 ± 0.24 f/ms respectively; endothelial cell density – 1521 ± 327 and 1475 ± 419 cells/mm2 respectively.Conclusion. Intrastromal corneal segments implantation into a corneal graft using a femtosecond laser has efficiency and safety method in correcting postkeratoplastic astigmatism.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>индуцированный астигматизм</kwd><kwd>интрароговичные сегменты</kwd><kwd>фемтосекундный лазер</kwd><kwd>кератопластика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>induced astigmatism</kwd><kwd>intracorneal segments</kwd><kwd>femtosecond laser</kwd><kwd>keratoplasty</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">Gu ZY, Ye MJ, Ji KK, Liao RF.
