Методы. Пациент М., 51 год, поступил с диагнозом: болезнь роговичного трансплантата, состояние после сквозной кератопластики, иридоартифакия, авитрия, субатрофия зрительного нерва, миопия высокой степени левого глаза. Для лечения болезни трансплантата пациенту была выполнена задняя послойная кератопластика с применением фемтосекундного лазера (ФСЛ) «ФемтоВизум» 1 МГц. Через 12 мес. после задней послойной фемтокератопластики для коррекции иррегулярного посткератопластического астигматизма и сопутствующей миопии высокой степени, выявленных после восстановления прозрачности сквозного роговичного трансплантата, выполнена имплантация кольца MyoRing в сквозной роговичный трансплантат с помощью ФСЛ. Результаты. После проведения задней послойной фемтокератопластики полностью восстановилась прозрачность сквозного роговичного трансплантата, а также стабилизировались показатели визометрии, рефрактокератометрии и кератопахиметрии к 6 мес. после операции. Через 12 мес. после задней послойной кератопластики с применением ФСЛ некорригированная острота зрения (НКОЗ) увеличилась с 0,03 до 0,06, корригированная острота зрения (КОЗ) — с 0,03 до 0,15. Потеря плотности эндотелиальных клеток заднего послойного трансплантата составила 27,4 %. Имплантация интрастромального кольца MyoRing в сквозной роговичный трансплантат позволила значительно повысить НКОЗ с 0,05 до 0,5, КОЗ — с 0,15 до 0,6. Сферический компонент рефракции снизился с -6,25 до -0,75 дптр, цилиндрический компонент рефракции — с -9,25 до -1,25 дптр, увеличились регулярность, сферичность роговичного трансплантата и его биомеханические свойства (фактор резистентности роговицы изменился с 8,2 до 9,4 мм рт. ст., корнеальный гистерезис — с 7,9 до 9,1 мм рт. ст.). Заключение. Комплексная этапная методика задней послойной фемтокератопластики с последующей имплантацией кольца MyoRing в роговичный трансплантат с применением фемтосекундного лазера является эффективным и безопасным методом лечения болезни трансплантата у пациента с имплантированной иридохрусталиковой диафрагмой и сопутствующей посткератопластической аметропией.</p></abstract><trans-abstract xml:lang="en"><p>The purpose: to analyze the clinical and functional results of the complex staged treatment of graft disease in patient with an implanted iris lens diaphragm and concomitant postkeratoplastic ametropia using descemet’s stripping endothelial keratoplasty using a femtosecond laser (FS-DSEK) and MyoRing implantation into a corneal graft using a femtosecond laser on the example of a clinical case. Methods. Patient M., 51 years old, was admitted with a diagnosis of the left eye: corneal transplant disease, condition after penetrating keratoplasty, iridoartifakia, avitria, optic nerve subatrophy, high myopia. To treat the graft disease, the patient underwent FS-DSEK using a FemtoVisum 1 MHz (Troitsk, Russia). Twelve months after FS-DSEK to correct irregular postkeratoplastic astigmatism and concomitant high-grade myopia detected after restoration of the transparency of the penetrating corneal graft, the MyoRing was implanted into the penetrating corneal graft using a femtosecond laser. Results. After performing FS-DSEK, the transparency of the penetrating corneal graft was completely restored, visometry, refractokeratometry, and keratopachymetric data were stabilized by 6 months after the operation. 12 months after FS-DSEK, uncorrected visual acuity (UCVA) increased from 1.6 to 1.2 LogMAR, best corrected visual acuity (BCVA) increased from 1.6 to 0.8 LogMAR. Loss of endothelial cell density of the posterior layered graft was 27.4 %. MyoRing implantation into a penetrating corneal graft made it possible to significantly increase the UCVA from 1.3 to 0.3 LogMAR and the BCVA from 0.8 to 0.2 LogMAR. The spherical component of refraction decreased from -6.25 to -0.75 D, the cylindrical component of refraction — from -9.25 to -1.25 D, the regularity, sphericity of the corneal graft and its biomechanical properties increased (corneal resistance factor increased from 8.2 to 9.4 mm Hg, corneal hysteresis — from 7.9 to 9.1 mm Hg). Conclusion. A complex staged technique of descemet’s stripping endothelial keratoplasty using a femtosecond laser followed by MyoRing implantation into the corneal graft using a femtosecond laser is an effective and safe method for treating graft disease in a patient with an implanted iris lens diaphragm and concomitant postkeratoplastic ametropia.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>задняя послойная кератопластика</kwd><kwd>посткератопластический астизматизм</kwd><kwd>кольцо MyoRing</kwd></kwd-group><kwd-group xml:lang="en"><kwd>descemet’s stripping endothelial keratoplasty</kwd><kwd>postkeratoplastic astismatism</kwd><kwd>MyoRing</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">Krysik K, Wroblewska-Czajka E, Lyssek-Boron A, Wylegala EA, Dobrowolski D.
