Пациенты и методы. В исследование вошел 31 пациент (31 глаз), которым была выполнена факоэмульсификация (ФЭ) с имплантацией ТИОЛ Clareon® Toric CNW0T2-T9 (Alcon, США). Биометрия передней поверхности роговицы выполнялась на аппарате IOL-Master 700 (Carl Zeiss, Германия), кератотопография обеих поверхностей роговой оболочки — на приборе CASIA OCT SS-1000 (Tomey, Япония). Расчет ТИОЛ производился по формулам Kane и BTC. Сравнивались параметры средней центроидной ошибки (СЦО), ее значения по модулю (МЦО), а также частота попадания в расчетные значения астигматизма в пределах ±0,25, ±0,50, ±0,75, ±1,00 и свыше 1,00 дптр. Результаты. Наименьшее значение СЦО (0,19 ± 0,92 дптр) и МЦО (0,82 ± 0,43 дптр), а также бóльшую частоту попадания (90 %) в расчетные значения астигматизма в пределах ±1,00 дптр обеспечила формула Kane, опирающаяся на параметры передней поверхности, полученные с помощью IOL-Master. Калькулятор BTC при учете данных передней поверхности роговицы, полученных на биометре IOL-Master, и задней — на топографе CASIA, оказался чуть менее точным — СЦО (0,27 ± 0,96 дптр), МЦО (0,86 ± 0,48 дптр), частота попадания в расчетные значения астигматизма в пределах ±1,00 дптр — 84 %. Заключение. Калькулятор Kane демонстрирует наилучшие рефракционные результаты расчета ТИОЛ при использовании стандартных данных кератометрии IOL-Master.</p></abstract><trans-abstract xml:lang="en"><p>Purpose. To compare Kane and Barrett toric formulas using different keratometric parameters. Material and methods. The study included 31 patients (31 eyes) who underwent phacoemulsification (PE) with implantation of the Clareon® Toric CNW0T2-T9 TIOL (Alcon, USA). Biometry was performed on IOL-Master 700 (Carl Zeiss, Germany), and keratopography on CASIA OCT SS-1000 device (Tomey, Japan). TIOL was calculated using Kane and Barrett toric calculator (BTC) formulas using various keratometric data. Mean centroid error (MCE) and mean absolute centroid error (MACE), frequency of target cylinder hitting within ±0.25, ±0.50, ±0.75, ±1.00, and over 1.00 D were compared. Results. The lowest MCE (0.19 ± 0.92 D) and MACE (0.82 ± 0.43 D), as well as a higher frequency of target cylinder hitting (90%) were shown by Kane formula when IOL-Master keratometric values were used. BTC was slightly less accurate — MCE (0.27 ± 0.96 D), MACE (0.86 ± 0.48 D), the frequency of target cylinder hitting within ±1.00 D was 84% when anterior corneal surface data by IOL-Master and the posterior corneal values by CASIA topographer were used. Conclusion. Kane formula demonstrates the best refractive results for TIOL calculation using standard IOL-Master keratometry data.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>факоэмульсификация</kwd><kwd>астигматизм</kwd><kwd>торические интраокулярные линзы</kwd><kwd>расчет ИОЛ</kwd><kwd>биометрия</kwd><kwd>кератотопография</kwd><kwd>астигматизм задней поверхности роговицы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>phacoemulsification</kwd><kwd>astigmatism</kwd><kwd>toric intraocular lenses</kwd><kwd>IOL calculation</kwd><kwd>biometry</kwd><kwd>keratotopography</kwd><kwd>posterior corneal astigmatism</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">Melles RB, Kane JX, Olsen T, Chang WJ.
