Оценка зрительных функций и сумеречного зрения у пациентов после имплантации различных видов ИОЛ

Abstract

Purpose. To compare NCOSIS in the distance, at an average distance and near, twilight vision and sensitivity to blinding in patients after implantation of various IOL models. Materials and methods. Сataract phacoemulsification was performed in 60 patients, Hoya iSert 250 IOL was implanted in Group I, Lentis Comfort IOL was implanted in Group II, Acrysof IQ PanOptix IOL was implanted in Group III. In the postoperative period, twilight vision and sensitivity to bright light were evaluated. Results. The threshold value with a contrast level of 1: 23 and 1: 5 without illumination was achieved in patients of all the studied groups in 100% of cases; with a contrast of 1:2 in 90% of cases in patients of group I, in 80% of cases-in patients of group II and III; with a contrast of 1:2.7 in 60% of groups I and II, in 50% in patients of group III. The threshold value with a contrast level of 1:23 was achieved in patients of all the studied groups in 100% of cases, with a contrast of 1:5 in 100% of cases in patients of groups I and III, in patients of group II in 80% of cases; with a contrast of 1:2.7 with illumination in 80% of patients of group I and 60% of patients of groups II and III; with a contrast of 1:2 and illumination in 50% of patients of group I, 40% of group II and 20% of patients of group III of the study. Conclusion. Under mesopic conditions with high contrast indicators, all three types of IOLs show equally high results of visual quality. In light conditions, monofocal IOL allows you to get a higher quality of vision in low contrast conditions, at high and medium levels, IOL indicators do not differ statistically significantly, with a significantly larger range of vision in bifocal and multifocal IOLs. Key words: cataract phacoemulsification, intraocular lenses, twilight vision.
