At the same time, surplus amount of stroma and nonuniform thickness of transplant limit achievement of potential acuity of vision. The development of laser femtosecond techniques permits to form transplant with different thickness and profile. The article presents medium-term biological and functional results of endothelial keratoplasty from the side of endothelium using transplant formed by femtosecond laser LDV Z6 (Ziemer, Switzerland). The sampling included 20 patients after end-to-end keratoplasty with primary and secondary endothelial dystrophy, with artiiridofaquia, avitria, and other concurrent pathology. The term of monitoring consisted 9.6±8.2 months (from 3 to 24 months). The transparency of cornea, acuity of vision, loss of density of endothelial cells, intra- and post-operation complications were studied. The regeneration of transparency of cornea was achieved in all 20 patients. During post-operation period, both complete and partial mismatch of transplant took place. The density of endothelial cells decreasing amounted to 46% in a month and 53% in three months. During three months of monitoring, average acuity of vision increased from 0.04±0.05 to 0.2±0.16. According information of authors, these are the first medium-term results of femtosecond endothelial keratoplasty with formation of flap from the side of endothelium. The results lead to suppose its effectiveness that is confirmed by regeneration of transparency of cornea in all examined patients. However, loss of density of cells in the given set of examinations remains unsatisfactory and analysis of functional results inadequate. There a necessity of further accumulation of experience, investigation of results and their analysis.</p></abstract><trans-abstract xml:lang="ru"><p>Автоматизированная кератомом эндотелиальная трансплантация с десцеметорексисом - в настоящее время наиболее часто выполняемая операция при патологии эндотелия роговицы. В то же время избыточное количество стромы и неравномерная толщина трансплантата ограничивают достижение потенциальной остроты зрения. Развитие лазерных фемтосекундных технологий позволяет формировать трансплантат с различной толщиной и профилем. Целью сообщения является представление среднесрочных биологических и функциональных результатов эндотелиальной кератопластики с использованием трансплантата, сформированного фемтосекундным лазером LDV Z6 (Ziemer, Швейцария) с эндотелиальной стороны. Прооперировано 20 пациентов, в том числе после сквозной кератопластики, с первичной и вторичной эндотелиальной дистрофией, с артииридофакией, авитрией и другой сопутствующей патологией. Срок наблюдения составил 9,6 ± 8,2 мес (от 3 до 24 мес). Изучались прозрачность роговицы, острота зрения, потеря плотности эндотелиальных клеток, интра- и постоперационные осложнения. Восстановление прозрачности роговицы достигнуто у всех 20 пациентов. "В послеоперационном периоде имели место как полное, так и частичное неприлегание трансплантата. Снижение плотности эндотелиальных клеток за 1 мес составило 46%, за 3 мес - 53%. Средняя острота зрения за 3 мес наблюдения увеличилась с 0,04 ± 0,05 до 0,2 ± 0,16. По нашим сведениям, это первые среднесрочные результаты фемтолазерной эндотелиальной кератопластики с формированием лоскута с эндотелиальной стороны. Они дают основание предполагать ее эффективность, что подтверждается восстановлением прозрачности роговиц у всех исследуемых пациентов. Однако потеря плотности клеток в данной серии исследований остается неудовлетворительной, а анализ функциональных результатов неполноценным. Необходимо дальнейшее накопление опыта, изучение результатов и их анализ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>DSEK</kwd><kwd>endothelial keratoplasty</kwd><kwd>femtosecond laser</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эндотелиальная кератопластика с десцеметорексисом</kwd><kwd>фемтосекундный лазер</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Lee W.B., Jacobs D.S., Musch D.C., Kaufman S.C., Reinhart W.J., Shtein R.M.
