The main technical task of all procedures of endothelial keratoplasty is an obligatory complete or almost complete post-operative adjacency of endothelial transplant to stroma of recipient. However, there are publications concerning resorption of edema in case of separation of endothelial transplant and even at its absence. The purpose of study. To analyze, on the basis of limited clinical observations, the results of partial discemetorexis (5.25 mm) without transplantation in patients with endothelial dystrophy of cornea (Fuchs).The materials and methods. The study was implemented concerning maximal correcting visual acuity, central thickness of cornea, density of endothelial cells and optical density of cornea, before, in one day, in one week, in 1, 3 and every 6 months after operation. The study covered 6 patients with Fuchs dystrophy (average age 63 ± 6,5 years) operated in 2015-2016 with period of observation neither less than 6 months. The visual acuity before operation in average made up to 0,32 ± 017 mkm, average central thickness of cornea - 677 ± 76 mkm. The native crystalline lens was present in 2 patients. The study was supported by ethical committee of the Helmholtz Moscow research institute of eyes diseases. The results. The resorption of edema of cornea occurred in 2 patients (33%), visual acuity increased from 0.45 to 0.6. In different periods density of endothelial cells varied from 549 to 689 kl/mm2. The central thickness of cornea decreased from 613 ± 33 mkm to 553 ± 15 mkm in 12 months after operation. Conclusion. The discemetorexis (5.25 mm) is more often efficient in case of availability of native crystalline lens, at earlier stages of dystrophy independently of patient's age. The discemetorexis ensures lower indices of maximal correcting visual acuity and density of endothelial cells and higher values of central thickness of cornea in comparison with DMEK. The indices of central thickness of cornea and optical density of cornea are exposed to fluctuations in different periods after discemetorexis (5.25 mm).</p></abstract><trans-abstract xml:lang="ru"><p>В последние 20 лет сквозная кератопластика уступила свое лидирующее место селективной послойной кератопластике, при которой избирательно заменяют патологически измененные слои роговицы, в том числе эндотелий. Основная техническая задача всех методик эндотелиальной кератопластики - обязательное полное либо почти полное послеоперационное прилегание эндотелиального трансплантата к строме реципиента. Однако в литературе есть сообщения о резорбции отёка при неприлегании эндотелиального трансплантата и даже при его отсутствии.Цель исследования. На основании ограниченных клинических наблюдений проанализировать результаты частичного десцеметорексиса (5,25 мм) без трансплантации у пациентов с эндотелиальной дистрофией роговицы (Fuchs).Материал и методы. Исследовали максимальную корригируемую остроту зрения (МКОЗ), центральную толщину роговицы (ЦТР), плотность эндотелиальных клеток (ПЭК) и оптическую плотность роговицы (ОПР) до, через 1 день, 1 нед, 1, 3 и каждые 6 мес после операции. В исследование вошли 6 пациентов с дистрофией Fuchs (средний возраст 63 ± 6,5 года), прооперированных в 2015 и 2016 гг., со сроком наблюдения не менее 6 мес. Острота зрения до операции в среднем составила 0,32 ± 017, средняя ЦТР 677 ± 76 мкм. У 2 больных присутствовал нативный хрусталик. Исследование одобрено этическим комитетом НИИ ГБ им. Гельмгольца.Результаты. Резорбция отёка роговицы произошла у 2 (33%) пациентов, острота зрения увеличилась с 0,45 до 0,6. В разные сроки ПЭК варьировала от 549 до 689 кл/мм2, ЦТР спустя 12 мес после операции уменьшилась с 613 ± 33 мкм до 553 ± 15 мкм.Заключение. Десцеметорексис (5,25 мм) эффективен чаще при наличии нативного хрусталика, на более ранних стадиях дистрофий, вне зависимости от возраста пациента; десцеметорексис обеспечивает более низкие, чем DMEK, показатели МКОЗ и ПЭК, большие величины ЦТР. Показатели ЦТР и ОПР подвержены флюктуациям в разные сроки после десцеметорексиса (5,25 мм).</p></trans-abstract><kwd-group xml:lang="en"><kwd>discemetorexis</kwd><kwd>endothelial keratoplasty</kwd><kwd>endothelial dystrophy</kwd><kwd>Fuchs dystrophy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>десцеметорексис</kwd><kwd>эндотелиальная кератопластика</kwd><kwd>эндотелиальная дистрофия</kwd><kwd>дистрофия Фукс</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Balachandran C., Ham L., Verschoor C.A., Ong T.S., van der Wees J., Melles G.R.
