Aim. To study the rehabilitative effect of treatment of cataracts by implanting trifocal refractive-diffractive soft intraocular lens MIOL-Record 3.Methods. 192 patients (216 eyes) who were operated on for cataract participated in the study. The first (main) group included 63 patients (72 eyes) in whom cataract extraction and implantation of the domestic trifocal refractive-diffractive monolithic (soft) intraocular lens MIOL-Record 3 was performed. The second group included 64 patients (70 eyes) in whom cataract extraction and implantation of the domestic bifocal refractive-diffractive lens MIOL-Accord was performed. The third group consisted of 65 patients (74 eyes) in whom cataract extraction and implantation of the domestic monofocal lens MIOL-2 was performed. Preoperative examination was performed the day before surgery, postoperative - after 7 days, 1, 3, 6 and 12 months.Results. The mean value of visual acuity at a distance of 50 cm without correction in the group of patients with MIOL-Record 3 1 month after surgery was 0.42±0.01 and was significantly higher than such in patients with MIOL-Accord and MIOL-2 - 0.14±0.01 and 0.1±0.001, respectively. A questionnaire survey revealed that in the group with MIOL-Record 3 additional correction with glasses is never used at the intermediate distance in 98.62% of the cases, in groups with MIOL-Accord - in 54.28%, and with MIOL-2 - in 25.68% of cases. Patients with MIOL-Record 3 were completely satisfied with the results of surgery in 70.84% of the cases, and in groups with MIOL-Accord and MIOL-2 - in 54.28, and 27.03% of cases, respectively.Conclusion. The conducted studies have established the best rehabilitative effect of the treatment of cataract during implantation of a trifocal refractive-diffractive intraocular lens MIOL-Record 3.
