Фемтолазерная факоэмульсификация катаракты с имплантацией трифокальных линз RayOne

Abstract

Purpose. To study the results of femtosecond laser-assisted cataract surgery (FLACS) using RayOne diffractive trifocal IOLs in comparison with bifocal lenses. Material and methods. The patients were divided into 2 groups: the first group included 32 patients (46 eyes) who were implanted with a bifocal refractive IOL M-flex 630 F with +3 dptr addidation during FPCS. The second group consisted of 34 people (49 eyes) with implanted RayOne trifocal IOL. The surgical treatment was evaluated by determining uncorrected visual acuity (UCVA) in the distance, at close (30-45 cm) and medium distance (50-70 cm) at discharge, 1 month and six months after the operation in photopic and mesopic lighting conditions, with the study of postoperative refractometry data, the construction of a defocusing curve, and subjective assessment of patient satisfaction. Results. A month after tthe operation the postoperative spheroequivalent in the range of ±0.5 D was achieved in group 1 in 82.6% of cases and in group 2-in 91.8. Six months after surgery near visual acuity without correction in photopic and mesopic light conditions was on average 0.61±0.08, while in patients of group 2, the average values were recorded at 0.64±0.09 and 0.62±0.07, respectively. By this time, the patients of group 1 had significantly lower rates of UCVA at long and medium distances: 0.81±0.08 in photopic lighting conditions and 0.79±0.08 in mesopic conditions, and group 2 0.41±0.08 and 0.40±0.10, respectively. Conclusion. Patients who underwent FLACS with an implanted RayOne trifocal IOL, compared with patients with bifocal IOLs, had higher rates of subjective satisfaction with the results of surgical treatment and UCVA at various distances (including greater comfort with actions performed at close and medium distances) at different light levels.
