Вероятность рефракционной ошибки особенно велика при расчете у пациентов с радиальной кератотомией (РК) в анамнезе. Единого подхода к тактике и методике расчета для данной категории пациентов на данный момент времени не выработано. Исследования проведены в группе из 17 пациентов (26 глаз) с РК в анамнезе. В качестве основной для расчета выбрана формула Haigis, не использующая кератометрию для прогнозирования эффективной позиции ИОЛ (ELP). Расчет ИОЛ и биометрия проводились на IOL-Master, но в опциональные поля кератометрии в ручном режиме вводились скорректированные данные TCP IOL (Ray Traced), полученные на кератотомографе Galilei. В качестве проверочных использованы формулы Burrett True-K и Hoffer Q, расчет проводился также на IOL-Master с использованием скорректированных данных Galilei. Во всех случаях получена послеоперационная рефракция, близкая к эмметропической. Сферический компонент рефракции составил от +0,5 до -1,0 дптр, цилиндрический — от 0,0 до 4,0 дптр по данным авторефрактометрии. Острота зрения без коррекции составила от 0,4 до 1,0. Некорригированная острота зрения 0,8 и выше получена в 65,38 % случаев. Реализованный алгоритм расчета с применением формулы Haigis в сочетании с использованием индивидуально скорректированных кератометрических данных TCP IOL (Ray Traced, Galilei) позволил значительно повысить точность расчета оптической силы ИОЛ у пациентов с РК в анамнезе и достичь целевой рефракции даже в случаях сложной и нерегулярной топографии роговицы. </p></abstract><trans-abstract xml:lang="en"><p>IOL power calculation after keratorefractive surgery is an important applied aspect of cataract surgery. The probability of refractive error is especially high when calculating in patients with a history of radial keratotomy. There is no unified approach to the tactics and methodology of calculation for this category of patients at the moment. The studies were conducted in a group of 17 patients (26 eyes) with a history of RK. The Haigis formula, which does not use keratometry to predict ELP, was chosen as the main one for the calculation. IOL calculation and biometrics were carried out on the IOL-Master, but corrected TCP IOL (Ray Traced) data obtained on the Galilei keratotomograph were manually entered into the optional keratometry fields. Thу Burrett True-K and Hoffer Q were used as verification formulas, the calculation was also carried out on IOL-Master, using corrected Galilei data. In all cases, postoperative refraction close to emmetropic was obtained. The spherical component of refraction ranged from +0.5 to -1.0 D, cylindrical — from 0.0 to 4.0 D, according to autorefractometry. Visual acuity without correction ranged from 0.4 to 1.0. Uncorrected visual acuity of 0.8 and higher was obtained in 65.38% of cases. The calculation algorithm implemented by us using the Haigis formula in combination with the use of individually adjusted keratometric TCP IOL data (Ray Traced, Galilei), allowed us to significantly improve the accuracy of IOL power calculating in patients with a history of RK and achieve target refraction even in cases of complex and irregular corneal topography. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>радиальная кератотомия</kwd><kwd>катаракта</kwd><kwd>расчет оптической силы ИОЛ</kwd><kwd>эффективная позиция ИОЛ</kwd><kwd>Scheimpflug-кератотомограф</kwd><kwd>технология Ray Traced</kwd><kwd>формула Haigis</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radial keratotomy</kwd><kwd>cataract</kwd><kwd>IOL power calculation</kwd><kwd>effective lens position</kwd><kwd>Scheimpflug-keratotomograph</kwd><kwd>Ray Traced technology</kwd><kwd>Haigis formula</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">Аветисов С.Э.
