Для определения толщины подлинзового водного слоя в вертикальном и горизонтальном меридианах было выполнено исследование у 33 человек на 46 глазах. Среди пациентов были 25 мужчин и 8 женщин в возрасте от 18 до 59 лет (в среднем 37,3 ± 9,5 года). Основным показанием для использования склеральных линз явилась неэффективность других методов коррекции зрения. </p></sec><sec><title>Результаты</title><p>Результаты. Среднее значение уменьшения толщины подлинзового водного слоя в общей группе обследованных пациентов, использующих склеральные линзы, составило 9,3 %, или 37,73 мкм, через 1 час ношения и 20,8 %, или 84,48 мкм, через 4 часа ношения по сравнению с исходными значениями.</p></sec><sec><title>Выводы</title><p>Выводы. Самые большие и клинически значимые изменения толщины подлинзового водного слоя происходят в течение первого часа ношения линзы, что составляет, по данным нашего исследования, примерно 40 микрон. Учитывая временну´ю динамику изменения толщины подлинзового водного слоя, окончательный расчет параметров необходимо производить не ранее чем через 1 час ношения склеральной линзы. Толщину подлинзового водного слоя необходимо оценивать в привязке ко времени, проведенному в склеральной линзе. По данным нашего обследования, за весь период наблюдения у всех пациентов, использующих склеральные линзы, происходит уменьшение толщины подлинзового водного слоя по мере увеличения длительности ношения, что требует дальнейшего дополнительного исследования для выявления точных причин и факторов, лежащих в основе данного процесса.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study. To analyze the change in the thickness of the sub­lens water layer depending on the time of wearing lenses in patients using scleral lenses using the SkyOptix Laboratory lenses as an example.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. To determine the thickness of the sublens water layer in the vertical and horizontal meridians, a study was performed in 33 people in 46 eyes. Among the patients there were 25 men and 8 women, from 18 to 59 years old (mean 37.3 ± 9.5 years). The main indication for the use of scleral lenses was the ineffectiveness of other methods of vision correction.</p></sec><sec><title>Results</title><p>Results. The mean sublens water layer thickness reduction in the total group of examined patients using scleral lenses was 9.3 % or 37.73 μm after 1 hour of wear and 20.8 % or 84.48 μm after 4 hours of wear compared to initial values.</p></sec><sec><title>Conclusions</title><p>Conclusions. The largest and clinically significant changes in the thickness of the sublens water layer occur during the first hour of lens wear, which, according to our study, is approximately 40 microns. Considering the temporal dynamics of changes in the thickness of the sublens water layer, the final calculation of the parameters must be made no earlier than after 1 hour of wearing the scleral lens. The thickness of the sublens water layer should be assessed in relation to the time spent in the scleral lens. According to our survey, over the entire period of observation in all patients using scleral lenses, there is a decrease in the thickness of the sublens water layer over time of wearing, which requires further additional research to determine identifying the exact causes and factors underlying this process.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>склеральные линзы</kwd><kwd>линзы</kwd><kwd>контактные линзы</kwd><kwd>клиренс</kwd><kwd>центральный клиренс</kwd><kwd>коррекция зрения</kwd><kwd>под­линзовый водный слой</kwd><kwd>кератоконус</kwd><kwd>кераторефракционные операции</kwd></kwd-group><kwd-group xml:lang="en"><kwd>scleral lenses</kwd><kwd>lenses</kwd><kwd>contact lenses</kwd><kwd>clearance</kwd><kwd>central clearance</kwd><kwd>vision correction</kwd><kwd>sublens water layer</kwd><kwd>keratoconus</kwd><kwd>keratorefractive surgery</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">Pullum KW, Buckley RJ.
