Внутрикапсульное положение ИОЛ является наилучшим с точки зрения оптики, а в анатомическом смысле приводит к формированию у пациента новой структуры — комплекса «ИОЛ — капсульный мешок» (КИКМ). Стабильное положение ИОЛ в послеоперационном периоде в ряде случаев может быть нарушено по причине фиброза капсульного мешка либо прогрессирующего инволюционного разрушения зонулярной связки на фоне псевдоэксфолиативного синдрома. Нарушение правильного положения оптики ИОЛ (наклон/децентрация) приводит к снижению зрения и появлению оптических аберраций. КИКМ является динамической структурой с точки зрения архитектоники. Уплотнение капсульных листков, увеличение размера экваториальных хрусталиковых масс (кольца Земмеринга) могут привести к изменению положения ИОЛ в отсроченном послеоперационном периоде. Точное определение данных параметров принципиально для оценки влияния на зрительные функции. Существующие методы определения положения ИОЛ основаны на разных принципах, поэтому сравнение параметров, полученных на разных приборах, некорректно.</p></sec><sec><title>Цель</title><p>Цель: разработать метод по определению наклона и децентрации интраокулярной линзы (ИОЛ) при помощи оптической когерентной томографии (Optovue, AS-OCT), а также определить данные параметры после шовной фиксации комплекса «ИОЛ — капсульный мешок» к радужной оболочке в отсроченном послеоперационном периоде.</p></sec><sec><title>Пациенты и методы</title><p>Пациенты и методы. Проведена оценка параметров 50 глаз, прооперированных в период 2014–2016 гг. по поводу дислокации КИКМ. Данные пациенты были повторно обследованы спустя 5 лет и более. Определение положения ИОЛ проводилось при помощи оптической когерентной томографии (Optovue, AS-OCT) с использованием протокола сканирования Cornea Crossline. Для оценки полученных параметров и отклонения их от нормы проведено сравнение исследуемой группы с группой из 30 артифакичных глаз и с высокой некорригированной остротой зрения.</p></sec><sec><title>Результаты</title><p>Результаты. В исследуемой группе получены следующие результаты: среднее значение угла наклона в горизонтальном меридиане ИОЛ составило 3,02° ± 2,04°, в вертикальном меридиане — 2,39° ± 1,40°. Децентрация относительно центра немидриатического зрачка составила в горизонтальном меридиане 396 ± 222 мкм, в вертикальном меридиане 455 ± 278 мкм. В группе сравнения: среднее значение угла наклона в горизонтальном меридиане ИОЛ составило 3,04° ± 1,28°, в вертикальном меридиане 1,43° ± 0,53°, децентрация относительно центра немидриатического зрачка в горизонтальном меридиане — 190 ± 114 мкм, в вертикальном меридиане 259 ± 108 мкм (p &lt; 0,05).</p></sec><sec><title>Заключение</title><p>Заключение. Разработанный метод позволяет бесконтактно определять положение ИОЛ (наклон/децентрация) при помощи оптической когерентной томографии (Optovue, AS-OCT). Полученные данные позволяют говорить о стабильном правильном фронтальном положении оптики ИОЛ при использовании шовной фиксации КИКМ к радужной оболочке в отсроченном послеоперационном периоде. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Intracapsular IOL position is optimal from optical point of view and in anatomical sense results in formation of a new structure — IOL-capsular bag complex (ICBC). Stable IOL position in post-op period in some cases may be disturbed in some cases due to capsular bag fibrosis or progressive involution zonulolysis against the background of pseudoexfoliation syndrome. The disturbance of correct IOL optic part position (tilt/decentration) results in a decrease of visual acuity and appearance of optic aberrations. ICBC is a dynamic structure from architectonic point of view. Fibrosis of capsular sheets and increase of equatorial cortex (Zommering ring) may result to IOL shift in long term post-op period. Accurate definition of these parameters is crucial for estimation of impact on visual functions. The existing methods of IOL position definition are based on various principles, therefore, it is not correct to compare the parameters obtained with various devices.</p></sec><sec><title>Pursope</title><p>Pursope. To develop a method of IOL tilt and decentration definition with optical coherence tomography (Optovue, AS-OCT) and to define these parameters after suture fixation of IOL-capsular bag complex to the iris in remote post-op period.</p></sec><sec><title>Methods</title><p>Methods. The parameters of 50 eyes operated from 2014 to 2016 for ICBC dislocation were estimated. The patients were examined again in 5 years or later. Definition of IOL position was performed with optical coherence tomography (Optovue, ASOCT) using Cornea Crossline protocol. For estimation of obtained parameters and their deviation from normal the study group was compared with a control group of 30 pseudophakic eyes with high uncorrected visual acuity.</p></sec><sec><title>Results</title><p>Results. In the study group the following data was obtained. Mean value of IOL tilt angle was 3.02 ± 2.04° in the horizontal meridian and 2.39 ± 1.4° in the vertical meridian. Decentration from the center of non-mydriatic pupil was 396 ± 222 microns in the horizontal meridian and 455 ± 278 microns in the vertical meridian. In the control group mean value of IOL tilt angle was 3.04° ± 1.28° in the horizontal meridian and 1.43° ± 0.53° in the vertical meridian. Decentration from the center of non-mydriatic pupil was 190 ± 114 microns in the horizontal meridian and 259 ± 108 microns in the vertical meridian. The difference between the groups is statistically significant (p &lt; 0,05).</p></sec><sec><title>Conclusion</title><p>Conclusion. The developed method allows non-contact definition of IOL position (tilt/decentration) with optical coherence tomography (Optovue, AS-OCT). The obtained data shows stable correct frontal position of IOL optic part in remote post-op period after suture fixation of ICBC to the iris. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>наклон/децентрация ИОЛ</kwd><kwd>контракционный капсулярный синдром</kwd><kwd>подшивание ИОЛ к радужке</kwd></kwd-group><kwd-group xml:lang="en"><kwd>IOL tilt / decentration</kwd><kwd>contraction capsular syndrome</kwd><kwd>IOL suturing to the iris</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">Kamiya K., Igarashi A., Hayashi K., Negishi K., Sato M., Bissen-Miyajima H.
