Проведено ретроспективное нерандомизированное исследование данных 174 пациентов (174 глаза), которым был выполнен гиперметропический ФемтоЛАЗИК. Все пациенты были разделены на три группы: I группа — пациенты с гиперметропией слабой степени (34 глаза), II группа — с гиперметропией средней степени (97 глаз), III группа — с гиперметропией высокой степени (43 глаза). Средний сфероэквивалент рефракции в I группе составил +1,94 ± 0,61 дптр, во II группе +3,8 ± 2,19 дптр, в III группе +5,7 ± 0,9 дптр. Проведена оценка стабильности кератотопографических данных после операции: показателей средней кератометрии, индекса регулярности поверхности (SRI) и индекса асимметрии поверхности роговицы (SAI). Оценка результатов проводилась на следующий день, через 1, 6 месяцев, через 1 и 3 года после оперативного вмешательства.</p></sec><sec><title>Результаты</title><p>Результаты. Статистически значимых изменений кератометрии в I и II группе в 1-й день после операции и через 3 года отмечено не было (p &gt; 0,05). В III группе определено статистически значимое снижение кератометрии через 6 месяцев после операции на 1,35 ± 2,48 дптр (p = 0,003), однако    в дальнейшем на протяжении 3 лет кератометрия оставалась стабильной (p &gt; 0,05). В I и II группах SRI статистически значимо увеличился по сравнению с дооперационными значениями на всех сроках после операции (p &lt; 0,05), во II группе отмечено увеличение SAI (p &lt; 0,05), в III группе SRI и SAI увеличились на всех сроках после операции (p &lt; 0,05). Однако, хотя увеличение индексов являлось статистически значимым, оно незначительно выходило за пределы нормальных значений.</p></sec><sec><title>Заключение</title><p>Заключение. Коррекция гиперметропии слабой и средней степени методом ФемтоЛАЗИК отличается значительной стабильностью кератотопографических данных на протяжении 3 лет после операции. Коррекция гиперметропии высокой степени сопряжена с постепенным уплощением роговицы в течение полугода после операции, однако далее в течение 3 лет остается стабильной, что важно учитывать в клинической практике для прогнозирования рефракционного эффекта.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose. To analyze changes of the corneal topography in the long-term period after hyperopic FS-LASIK in patients with low, moderate and high hyperopia.</p></sec><sec><title>Patients and Methods</title><p>Patients and Methods. This retrospective non-randomized study included data of 174 patients (174 eyes). All patients were performed hyperopic FS-LASIK. All patients were divided into three groups. Group I included patients with low hyperopia (34 eyes), group II included patients with moderate hyperopia (97 eyes), group III included patients with high hyperopia (43 eyes). Before the surgery, the mean cycloplegic spherical equivalent in group I was +1.94 ± 0.61 D, in group II +3.8 ± 2.19 D, in group III +5.7 ± 0.9 D. The stability of corneal topography after surgery was analyzed: mean keratometry, Surface Asymmetry Index (SAI), Surface Regularity Index (SRI). The results were evaluated the day after the surgery, 1 month later, 6 months later, 1 year later and 3 years after the surgery.</p></sec><sec><title>Results</title><p>Results. There were no statistically significant changes in keratometry in groups I and II on the first day after surgery and 3 years later (p &gt; 0.05). In group III, there was a statistically significant decrease in keratometry at 6 months after surgery by 1.35 ± 2.48. D (p = 0.003); however, keratometry remained stable for 3 years thereafter (p &gt; 0.05). In groups I and II, SRI increased at all periods after surgery (p &lt; 0.05), in group II there was an increase in SAI (p &lt; 0.05), in group III, SRI and SAI increased at all periods after surgery (p &lt; 0.05). Although the increase in the indices was statistically significant, it slightly exceeded the normal limits.</p></sec><sec><title>Conclusions</title><p>Conclusions. After correction of low and moderate hyperopia by FS-LASIK, corneal topography remains stable for 3 years after surgery. Correction of high hyperopia is associated with gradual flattening of the cornea within six months after surgery, but then keratometry remains stable for 3 years. It is important to take it into account in clinical practice.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ФемтоЛАЗИК</kwd><kwd>гиперметропия</kwd><kwd>кератотопография</kwd><kwd>кератометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>FS-LASIK</kwd><kwd>hyperopia</kwd><kwd>corneal topography</kwd><kwd>keratometry</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">Barrett BT, Bradley A, Candy TR.
