Гипоксическая кератопатия (ГК) при длительном ношении контактных линз — наиболее частая причина дис-регенераторных состояний после кераторефракционной хирургии. Цель работы — изучение взаимосвязи осмолярности слезы, индекса поражения глазной поверхности и in vivo гистоморфологических показателей роговицы у пациентов, длительно пользующихся контактными линзами. Пациенты и методы. Обследовано 3 группы пациентов с ГК легкой степени (34 чел.), средней степени (32 чел.) и тяжелой степени (29 чел.). Контролем служили 34 здоровых волонтера. Всем пациентам однократно проводили конфокальную микроскопию роговицы, исследование осмолярности слезы и вычисление индекса поражения глазной поверхности (OSDI). результаты и обсуждение. В контрольной группе по данным конфокальной микроскопии визуализировалась интактная роговица, индекс OSDI составил в среднем 5,1±0,9 балла, а осмолярность слезы — 291,3±9,8 мОсм/л, что соответствовало норме. При ГК слабой степени отмечена умеренная псевдокератинизация эпителия роговицы, индекс OSDI составил в среднем 20,8±4,4 балла, что соответствовало легкому поражению глазной поверхности, а осмолярность слезы — 308,9±23,2, что у большинства пациентов не выходило за границы нормы. При ГК средней степени в роговице визуализиро-вались изменения во всех слоях роговицы с превалированием признаков асептического воспаления; индекс OSDI составил в среднем 22,9±7,2 балла, что достоверно не отличалось от ГК слабой степени, а осмолярность значительно превышала ГК лег-кой степени (332,3±14,2, p&lt;0.05). ГК тяжелой степени характеризовалась выраженными изменениями во всех слоях рогови-цы с преобладанием аутоиммунных воспалительных и дистрофических процессов, индекс OSDI был существенно выше, чем при ГК средней степени (62,5±9,7, p&gt;&lt;0.001), а величина осмолярности слезы (364,9±26,7 мОсм/л) соответствовала средней или тяжелой степени синдрома сухого глаза. &gt;заключение. Применение в практике рефракционных хирургов скрининговых методов оценки ГК позволяет обеспечить быструю оценку состояния глазной поверхности при ношении контактных линз и за счет проведения превентивных и корригирующих мероприятий снизить вероятность послеоперационных дисрегенераторных состояний.</p></abstract><trans-abstract xml:lang="en"><p>background. Hypoxic keratopathy (HK) is the most common cause of dysregenerative conditions after corneal refractive surgery in case of long-term contact lenses wears. purpose: to study the correlation between the tears osmolarity, OSDI index and in vivo histo-morphological lesions in the corneas in patients with long-term contact lenses use. patients and methods. 3 groups of patients with mild (34 people), moderate (32 people) and severe (29 people) degrees of HK were examined. Control group consisted with 34 healthy volunteers. In all patients we performed the confocal microscopy of the cornea, the tears osmolarity assess and the calculation of the OSDI index. results and discussion. According to the confocal microscopy the intact corneas were visualized in the controls as well as the mean OSDI index was 5.1±0.9 points, and the tears osmolarity was 291,3 of ±9.8 mOsm/l, which corresponded to the norm. In the mild degree of HK the moderate pseudo-keratinization of the corneal epithelium was noted, the OSDI index was 20.8±4.4 points, which corresponded to the initial lesion of the ocular surface, and the tears osmolarity was 308.9±23 (most patients were within the limits of the norm values). In the moderate degree of HK cornea showed the changes in all layers with a prevalence of noninfectious inflammation signs; mean OSDI index was 22.9±7.2 points that was not significantly different from the mild HK, and osmolality greatly exceeded the mild HK (332,3±14,2, p&lt;0.05). Severe HK was characterized by the significant changes in all corneal layers with a prevalence of autoimmune inflammatory and degenerative processes; mean OSDI index was significantly higher than in moderate degree of the HK (62,5±9,7, p&lt;0.001), and the value of the tears osmolarity (364,9±26,7 mOsm/l) corresponds to the moderate or severe dry eye syndrome. Conclusion. The screening methods for the HK evaluation in refractive surgery will provide a rapid assessment of the ocular surface during contact lens wear and by conducting the preventive and corrective measures will reduce the frequency of the postoperative dysregenerative conditions. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>гипоксическая кератопатия</kwd><kwd>контактные линзы</kwd><kwd>кераторефракционные операции</kwd><kwd>дисрегенераторные состояния</kwd><kwd>синдром сухого глаза</kwd><kwd>осмолярность слезы</kwd><kwd>конфокальная микроскопия</kwd><kwd>индекс поражения глазной поверхности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hypoxic keratopathy</kwd><kwd>contact lens</kwd><kwd>corneal refractive surgeries</kwd><kwd>dysregenerative conditions</kwd><kwd>dry eye syndrome</kwd><kwd>the tears osmolarity</kwd><kwd>confocal microscopy</kwd><kwd>OSDI</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">Raoof D., Pineda R.
