Обследованы 55 пациентов (55 глаз), которым была проведена факоэмульсификация катаракты (ФЭК) или рефракционная ленсэктомия с фемтолазерным сопровождением и имплантацией мультифокальной ИОЛ (Acrysof IQ PanOptix) с достижением рефракции цели на разных расстояниях. Ретроспективный расчет оптической силы ИОЛ проводили по биометрическим данным OA-2000 и кератометрическим показателям Pentacam (зоны от 0,5 до 5 мм с шагом 0,5 мм по карте Axial/Sagittal с центрацией по апексу и зрачку) с использованием 10 формул (SRK/T, Holladay 1, Holladay 2, Haigis, Hoffer Q, Barrett 2 Universal, Olsen, Kane, EVO ver. 2.0, Hill RBF ver. 3.0). Для каждой комбинации «зона / значение кератометрии / формула» рассчитана средняя ошибка послеоперационной прогнозируемой рефракции, отличие ее от нуля (критерий Уилкоксона), значение медианы с учетом знака, средняя (MAE) и срединная (MedAE) абсолютные ошибки расчета сферического эквивалента ИОЛ, стандартное отклонение средней абсолютной ошибки (SD).</p></sec><sec><title>Результаты</title><p>Результаты. Для всех формул наблюдался сдвиг в миопическую рефракцию, кроме формулы Haigis, которая смещалась в сторону гиперметропии. Отсутствие достоверного отличия от нуля показала только формула Kane в зонах 3,5, 4,5–5,0 мм при центрации по апексу и в зонах 0,5, 1,5, 2,5–5,5 мм при центрации по зрачку. Самые высокие значения MAE обнаружены у формул Haigis и Olsen, а минимальные показатели наблюдались у большинства формул в зонах 4,5–5,0 мм. Самые низкие значения MedAE во всех диапазонах показали формулы Kane, EVO, Holladay 1 и Holladay 2. Минимальные значения SD выявлены у формул Kane, EVO, Holladay 1 и Holladay 2.</p></sec><sec><title>Заключение</title><p>Заключение. Наиболее точной оказалась формула Kane в зоне 4,5–5,0 мм, затем следуют формулы EVO 2 и Holladay 1 в 4,0-мм зоне. Формула Haigis оказалась наименее точной. Остальные формулы могут быть рекомендованы к использованию с данными SimK Pentacam в зонах 4,0–5,0 мм.</p></sec></abstract><trans-abstract xml:lang="en"><p>Purpose of the study is to determine the zones of standard keratometry according to keratotopography data, which will allow for more accurate calculation of multifocal IOL using 10 formulas.</p><sec><title>Material and methods</title><p>Material and methods. The study included 55 patients (55 eyes) who underwent phacoemulsification of cataract or refractive lensectomy with femtolaser accompaniment, implantation of multifocal IOL (Acrysof IQ PanOptix) and achieved the target refraction at different distances. Retrospective calculation of the optical power of the IOL was carried out using biometric data from OA-2000 and keratometric indicators of Pentacam (zones from 0.5 mm to 5 mm in increments of 0.5 mm on the Axial/Sagittal map centered on the apex and pupil) using 10 formulas (SRK/T, Holladay 1, Holladay 2, Haigis, Hoffer Q, Barrett 2 Universal, Olsen, Kane, EVO ver. 2.0, Hill RBF ver. 3.0). For each combination of zone/keratometry value/formula, the average error of postoperative predicted refraction, its difference from zero (Wilcoxon criterion), the median value taking into account the sign, the mean (MAE) and median (MedAE) absolute errors in calculating the spherical equivalent of the IOL, the standard deviation of the mean absolute error (SD) were calculated.</p></sec><sec><title>Results</title><p>Results. All formulas had a shift to myopic refraction, except for the Haigis formula, which shifted towards hyperopia. The absence of a significant difference from zero was shown only by the Kane formula in zones 3.5, 4.5–5.0 mm when centered on the apex and in zones 0.5, 1.5, 2.5–5.5 mm when centered on the pupil. The highest values of MAE were found in Haigis and Olsen formulas, and the minimum values were observed in most formulas in the 4.5–5.0 mm zones. The lowest MedAE values in all ranges were shown by the formulas Kane, EVO, Holladay 1 and Holladay 2. The minimum SD values were found for the formulas Kane, EVO, Holladay 1 and Holladay 2.</p></sec><sec><title>Conclusion</title><p>Conclusion. The Kane formula turned out to be the most accurate in the 4.5–5.0 mm zone. This is followed by the EVO 2 and Holladay 1 formulas in the 4.0 mm zone. The Haigis formula turned out to be the least accurate. The remaining formulas can be recommended for use with SimK Pentacam data in 4.0–5.0 mm zones.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>кератометрия</kwd><kwd>кератотопография</kwd><kwd>зона роговицы</kwd><kwd>мультифокальная ИОЛ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>keratometry</kwd><kwd>keratotopography</kwd><kwd>corneal zone</kwd><kwd>multifocal IOL</kwd></kwd-group><funding-group><funding-statement xml:lang="en">no author has a financial or property interest in any material or method mentioned</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Малюгин Б.Э., Морозова Т.А.
