Снижение прозрачности роговицы приводит к рассеиванию энергии фемтосекундного лазера (ФСЛ), что может затруднять формирование интрастромальных разрезов и ограничивать его использование на глазах с рубцами и помутнениями. Цель данной работы — демонстрация возможности успешного выполнения операции по технологии ReLEx SMILE у пациентки с поверхностным помутнением роговицы, располагающимся в парацентральной зоне.  Клинический случай. Пациентка Р., 29 лет, обратилась с жалобами на снижение зрения обоих глаз с детства. При проверке острота зрения OD = 0,1 с коррекцией sph –2,75D = 1,0; OS = 0,1 с коррекцией sph –3,50D cyl –0,75D ax 165° = 1,0. При биомикроскопии правого глаза визуализировалось поверхностное полупрозрачное помутнение роговицы размером 5×3 мм, располагающееся на 5.30–6 часах на расстоянии 1,3 мм от оптического центра. По данным оптической когерентной томографии (ОКТ) переднего отрезка глаза глубина залегания помутнения составила 73–78 мкм и была ограничена боуменовой мембраной. Для коррекции миопии проведена операция по технологии ReLEx SMILE на обоих глазах с формированием лентикулы диаметром 6,7 мм, расположенной на глубине 120 мкм, которая перекрывала зону помутнения на 1,1 мм. Операция прошла стандартно, интраоперационных осложнений не было. Через 7 дней после операции пациентка жалоб не предъявляла. Некорригированная острота зрения (НКОЗ) составила 1,0 на оба глаза (бинокулярно 1,2). По данным ОКТ переднего отрезка на правом глазу на глубине 141–147 мкм визуализировалась гиперрефлективная линия — зона интерфейса; в нижних парацентральных отделах над этой линией визуализировалось помутнение поверхностных слоев роговицы. Через 1 месяц после операции острота зрения пациентки не изменилась: НКОЗ = 1,0 на обоих глазах (бинокулярно 1,2).  Заключение. Технология ReLEx SMILE может быть рассмотрена как один из вариантов лазерной коррекции при поверхностных помутнениях роговицы, расположенных в парацентральной зоне. Требуется большее количество наблюдений для оценки эффективности данной технологии на роговице с парацентральным помутнением, различным по размеру и располагающимся на разной глубине.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Reduced corneal transparency leads to dissipation of energy of the femtosecond laser (FSL), which may complicate the formation of the intrastromal incision and limits the use of FSL in eyes with corneal opacities and scars. The purpose of this work is to demonstrate the possibility of successful ReLEx SMILE in a patient with superficial corneal opacity located in the paracentral zone.  Case report. Patient R., 29 years old, complained of decreased vision in both eyes since childhood. Visual acuity OD = 0.1 sph –2.75D = 1.0; OS = 0.1 sph –3.50 D cyl –0.75D ax 165° = 1.0. Biomicroscopy of the right eye visualized a superficial semi-transparent corneal opacity of 5 x 3 mm located at 5.30–6 hours at a distance of 1.3 mm from the optical center. According to the anterior segment optical coherence tomography (AS-OCT) the depth of the opacity was 73–78 microns and was limited by the Bowman’s membrane. ReLEx SMILE for myopia correction was performed on both eyes with 6.7 mm lenticule diameter at a depth of 120 µm, which covered the opacity area by 1.1 mm. The surgery was standard and uncomplicated. Seven days postoperatively the patient did not complain. Uncorrected visual acuity (UCVA) was 1.0 for both eyes (and binocularly it was 1.2). According to the AS-OCT data, a hyperreflective line of the interface zone was visualized on the right eye at the depth of 141–147 µm; the opacified superficial corneal layers were detected in the lower paracental zone over the interface line. In one month after the surgery the visual acuity did not change: UCVA = 1.0 in both eyes (binocularly 1.2).  Conclusion. ReLEx SMILE technology can be considered as one of the options for myopia correction in patients with superficial corneal opacity located in the paracental zone. More observations are required to evaluate the effectiveness of this technology on corneas with paracentral opacities different in sizes and located at different depths.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фемтосекундный лазер</kwd><kwd>ReLEx SMILE</kwd><kwd>роговица</kwd><kwd>помутнение</kwd><kwd>миопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>femtosecond laser</kwd><kwd>ReLEx SMILE</kwd><kwd>cornea</kwd><kwd>opacity</kwd><kwd>myopia</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">Sletten K.R., Yen K.G., Sayegh S., Loesel F., Eckhoff C., Horvath C., et. al.
