В дизайне проспективного исследования обследованы 78 пациентов (118 глаз). В опытную группу (I) вошли 30 пациентов (52 глаза) с экстремально короткими глазами (средняя аксиальная длина глаза 18,54–20,00 мм (19,60 ± 0,42), группу сравнения (II) составили 48 пациентов (66 глаз) с нормальной аксиальной длиной 22,00–23,77 (22,75 ± 0,46) мм. Всем пациентам имплантировали различные модели монофокальной ИОЛ. Средний период наблюдения составил 13 месяцев. Расчет оптической силы ИОЛ проводили по формуле SRK/T, ретроспективное сравнение — по формулам Hoffer-Q, Holladay II, Olsen, Haigis, Barrett Universal II и Kane.</p></sec><sec><title>Результаты</title><p>Результаты. В группе I максимальная средняя погрешность оценки определена для формулы Haigis (0,88 ± 0,35), далее для формул Olsen, Barrett Universal II, Kane, SRK/T, Holladay 2 и Hoffer-Q (0,51 ± 0,12, 0,16 ± 0,38, 0,13 ± 0,28, 0,10 ± 0,59, 0,05 ± 0,54 и –0,12 ± 0,42 соответственно). Схожие данные получены и для средней абсолютной погрешности — для формул Haigis, Olsen, Barrett Universal II, SRK/T, Holladay 2, Hoffer-Q и Kaneона: 0,85 ± 0,31, 0,78 ± 0,25, 0,21 ± 0,10, 0,79 ± 0,23, 0,73 ± 0,24, 0,19 ± 0,08 и 0,17 ± 0,06 соответственно. При сравнении формул значимые различия выявлены для формул Hoffer-Q, Barrett Universal II и Kane в сравнении с формулами Haigis, Olsen, SRK/T и Holladay II (p &lt; 0,05) во всех случаях, что свидетельствует о преимуществе указанных формул для группы пациентов с экстремально короткими глазами. В группе II значимых различий между исследуемыми формулами не выявлено (p &gt; 0,05).</p></sec><sec><title>Заключение</title><p>Заключение. В настоящей работе представлен анализ собственных данных об эффективности шести формул для расчета оптической силы ИОЛ на экстремально коротких глазах (менее 20 мм) в сравнении с глазами с нормальной аксиальной длиной. Показано преимущество формул Hoffer-Q, Barrett Universal II и Kane по сравнению с Haigis, Holladay 2, Olsen и SRK/T. Для определения точных показаний к использованию данных формул необходимы дальнейшие исследования с учетом глубины передней камеры и меньшей степени гиперметропии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose: to choose the optimal formula for calculating the IOL optical power in patients with an axial eye length of less than 20 mm.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. A total of 78 patients (118 eyes) were included in the prospective study. Group I included 30 patients (52 eyes) with extremely short eyes (average axial eye length of 19.60 ± 0.42 (18.54–20.00) mm), group II consisted of 48 patients (66 eyes) with a normal axial length 22.75 ± 0.46 (22.00–23.77) mm with implantation of various monofocal IOL models. The average follow-up period was 13 months. IOL optical power was calculated using the SRK / T formula, retrospective comparison — according to the formulas Hoffer-Q, Holladay II, Olsen, Haigis and Barrett Universal II.</p></sec><sec><title>Results</title><p>Results. In group I, the maximum average estimation error was determined for the formula Haigis (0.88 ± 0.35), then for the formula Olsen, Barrett Universal II, Kane, SRK / T, Holladay 2 and Hoffer-Q (0.51 ± 0.12, 0.16 ± 0.38, 0.13 ± 0.28, 0.10 ± 0.59, 0.05 ± 0.54 and –0.12 ± 0.42, respectively). Similar data were obtained for the average absolute error — for the formulas Haigis, Olsen, Barrett Universal II, SRK / T, Holladay 2, Hoffer-Q and Kane, it was 0.85 ± 0.31, 0.78 ± 0.25, 0.21 ± 0.10, 0.79 ± 0.23, 0.73 ± 0.24, 0.19 ± 0.08 and 0.17 ± 0.06, respectively. When comparing the formulas, significant differences were found for the formulas Hoffer-Q, Barrett Universal II and Kane in comparison with the formulas Haigis, Olsen, SRK / T and Holladay II (p &lt; 0.05) in all cases, respectively, which indicates the advantage of these formulas for the group patients with extremely short eyes. In group II, there were no significant differences between the studied formulas (p &gt; 0.05).</p></sec><sec><title>Conclusion</title><p>Conclusion. This paper presents an analysis of our own data on the effectiveness of six formulas for calculating the IOL optical power in extremely short (less than 20 mm) eyes in comparison with the normal axial length. The advantage of the Hoffer-Q, Barrett Universal II and Kane formulas over Haigis, Holladay 2, Olsen, and SRK / T is shown. To determine the exact indications for using these formulas, further studies are necessary taking into account the anterior chamber depth and a lesser degree of hyperopia.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>катаракта</kwd><kwd>гиперметропия</kwd><kwd>короткие глаза</kwd><kwd>расчет оптической силы ИОЛ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cataract</kwd><kwd>hypermetropia</kwd><kwd>short eyes</kwd><kwd>calculation of the IOL optical power</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">Hahn U., Krummenauer F., Kolbl B., Neuhann T., Schayan-Araghi K., Schmickler S., von Wolff K., Weindler J., Will T., Neuhann I.
