The study sampling included 22 patients underwent UTinvFS-DSEK during 2012-2014 in the Helmholtz Moscow research institute of eye diseases. The average time-period of observation made up to 9.6 ± 4.3 months. The Fuchs dystrophy occurred in 31.8%, secondary dystrophy - in 45.4%, inconsistency of endothelium of kerato-transplant - in 22%. All patients were applied photo-registration, visiometry, auto-refractokeratometry, bio-microscopy, tonometry, kerato-analyzing, optical coherent tomography of front segment, confocal microscopy. During the first three years after transplantation, the average loss by endothelium cells made up to 60% of initial level. At that, average loss of density of endothelium cells made up to 1256 ± 450 cells per mm2. In time-periods of six months after surgery the average loss of density of endothelium cells made up to 64% of initial level. The loss of density of endothelium cells remained at the level of 64% after 12 months. In two patients under observation the average density of endothelium cells made up to 996±161 cells per mm 2 after 24 months. The analysis of dynamics of loss by endothelium cells after applied keratoplastry with formation of transplant using femtosecond laser from the side of endothelium demonstrated that received values of loss by cells in existing time-periods exceed, according publications' data, similar indicator after reach-through keratoplastry, standard endokeratoplastry and transplantation of Descemet's membrane with endothelium. The actual study has such certain limitations as average time-periods of observation, limited number of patients, minimal number of patients within time-period more than 24 months.</p></abstract><trans-abstract xml:lang="ru"><p>Представлены результаты анализа потери плотности эндотелиальных клеток (ПЭК) после эндотелиальной кератопластики с формированием ультратонкого трансплантата фемтосекундным лазером со стороны эндотелия (UTinvFS- DSEK). В исследование включены 22 пациента, которым в ФГУ МНИИ ГБ им. Гельмгольца в период с 2012 по 2014 г. была проведена UTinvFS-DSEK. Средний срок наблюдения составил 9,6 ± 4,3 мес. В 31,8% случаев имела место дистрофия Фукса в 45,4% - вторичная дистрофия, в 22% - несостоятельность эндотелия кератотрансплантата. Всем пациентам проводились фоторегистрация, визометрия, авторефрактокератометрия, биомикроскопия, тонометрия, кератоанализирование, оптическая когерентная томография переднего отрезка, конфокальная микроскопия. За первые 3 мес после трансплантации средняя потеря клеток эндотелия составила 60% от исходного уровня, при этом средняя ПЭК составила 1256 ± 450 клеток/мм 2. В сроки 6 мес после операции потеря плотности в среднем составила 64% от исходного уровня. Через 12 мес потеря ПЭК сохранилась на уровне 64%. Через 24 мес у двух находящихся под наблюдением пациентов средняя плотность эндотелиальных клеток составила 996 ± 161 клеток/мм 2. Изучение динамики потери эндотелиальных клеток после выполненных кератопластик с формированием трансплантата фемтосекундным лазером со стороны эндотелия показало, что полученные значения потери клеток в имеющиеся сроки наблюдения превышают, по данным литературы, аналогичный показатель после сквозной кератопластики, стандартной эндокератопластики (DSEK) и трансплантации десцеметовой мембраны с эндотелием (DMEK). Данное исследование имеет ряд ограничений, таких как средние сроки наблюдения, ограниченное количество пациентов, минимальное количество пациентов в сроки наблюдения более 24 мес.</p></trans-abstract><kwd-group xml:lang="en"><kwd>DSEK</kwd><kwd>endothelium keratoplastry with descemetorexis</kwd><kwd>femtosecond laser</kwd><kwd>standard endokeratoplastry</kwd><kwd>density of endothelium cells</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эндотелиальная кератопластика с десцеметорексисом</kwd><kwd>фемтосекундный лазер</kwd><kwd>плотность эндотелиальных клеток</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Shtein R.M.
