В исследование вошли 37 пациентов (50 глаз) с роговичным астигматизмом до -5,0 дптр, прооперированных методом фемтолазерной ИСКП с имплантацией роговичных сегментов. Средний возраст пациентов составил 27,96 ± 3,40 года. Срок наблюдения — от 3 до 12 месяцев. В зависимости от методики выполнения хирургического вмешательства: Verion-ассистированной с применением цифрового разметочного устройства и учетом угла циклоторсии или стандартного без учета угла циклоторсии — все пациенты были разделены на две группы. Соответственно, в первую основную группу вошло 28 глаз (56 %), во вторую контрольную группу — 22 глаза (44 %).</p></sec><sec><title>Результаты</title><p>Результаты. Функциональные результаты после ИСКП в обеих группах были достаточно высокими. В послеоперационном периоде к 3 месяцам отмечена стабилизация функциональных показателей и кератометрических данных. У пациентов основной группы выявлено статистически значимое (р &lt; 0,05) увеличение средней некорригированной остроты зрения до 0,50 ± 0,16, а остроты зрения с максимальной коррекцией — до 0,70 ± 0,12 (р &lt; 0,05). Средние значения кератометрии слабого меридиана снизились до 44,3 ± 1,4 дптр, средние значения кератометрии сильного меридиана — до 50,8 ± 3,2 дптр. У пациентов контрольной группы отмечалось статистически значимое (р &lt; 0,05) увеличение средней некорригированной остроты зрения до 0,45 ± 0,12, а остроты зрения с максимальной коррекцией — до 0,60 ± 0,17. Средние значения кератометрии слабого меридиана снизились до 45,3 ± 1,8 дптр, средние значения кератометрии сильного меридиана — до 51,8 ± 2,2 дптр. Результаты векторного анализа достоверно свидетельствуют о значительно более высокой точности Verion-ассистированной ИСКП, что подтверждается достигнутыми показателями индекса «успеха», расчетного вектора астигматизма, приближенного к фактическому послеоперационному, меньшей величиной вектора разницы оси астигматизма по сравнению с контролем.</p></sec><sec><title>Заключение</title><p>Заключение. Применение Verion-ассистированной интрастромальной методики при кератоконусе снижает риск ошибочного позиционирования роговичных сегментов в тоннель при переносе данных диагностики в операционную, а учет угла циклоторсии при выполнении вреза в интрастромальный тоннель повышает результативную коррекцию цилиндрического компонента рефракции, что подтверждается основными коэффициентами проведенного векторного анализа по N.

These patients were operated with the femtolaser method of ISKP with implantation of corneal segments. The average age of the patients was 27.96 ± 3.40 years. The observation period is from 3 to 12 months. All patients were divided into two groups depending on the surgical technique: Verion-assisted, using a digital marking device and taking into account the angle of cyclotorsia, or standard, without taking into account the angle of cyclotorsia. The first main group included 28 eyes (56 %), the second control group included 22 eyes (44 %) accordingly.</p></sec><sec><title>Results</title><p>Results. The functional results after ISKP in both groups were quite good. Stabilization of functional parameters and keratometric data was noted in the postoperative period, by 3 months. Patients of the main group showed a statistically significant (p &lt; 0.05) increase in average uncorrected visual acuity to 0.50 ± 0.16, and visual acuity with maximum correction to 0.70 ± 0.12 (p &lt; 0.05). The average keratometry of the weak meridian decreased to 44.3 ± 1.4 diopters, the average keratometry of the strong meridian decreased to 50.8 ± 3.2 diopters. Patients in the control group showed a statistically significant (p &lt; 0.05) increase in average uncorrected visual acuity to 0.45 ± 0.12, and visual acuity with maximum correction to 0.60 ± 0.17. The average values of keratometry of the weak meridian decreased to 45.3 ± 1.8 diopters, the average values of keratometry of the strong meridian decreased to 51.8 ± 2.2 diopters. The results of the vector analysis reliably indicate a significantly higher accuracy of the Verion-assisted ISKP. Which is confirmed by the achieved indicators of the “success” index, the calculated astigmatism vector close to the actual postoperative astigmatism vector, the smaller the magnitude of the astigmatism axis difference vector compared to the control.</p></sec><sec><title>Conclusion</title><p>Conclusion. The use of the Verion-assisted intrastromal technique for keratoconus reduces the risk of erroneous positioning of the corneal segments in the tunnel during transferring diagnostic data to the operating room. Taking into account the angle of cyclotorsia during cutting into the intrastromal tunnel increases the effective correction of the cylindrical component of refraction, which is confirmed by the main coefficients of the vector analysis by N.
