Abstract
Purpose. To evaluate long-term results of AcrySof IQ Vivity non-diffractive extended-focus intraocular lens (IOL) implantation. Material and methods. 20 patients (20 eyes) underwent phacoemulsification and implanted non-diffractive IOL with expanded depth of focus. The mean age of the patients was 64.4 years (54 to 70 years). All patients were followed up for one year. Long-term results were analyzed. The postoperative period was smooth. Two patients developed secondary cataract 6 months later and IAG-laser discectomy of the posterior capsule was performed. Results. In 12 months after surgery, the uncorrected visual acuity (UCVA) in the distance was — 0.88 ± 0.06, at the middle distance — 0.77 ± 0.02, in the vicinity — 0.60 ± 0.05. Best corrected visual acuity in the distance — 0.93 ± 0.04, in the middle distance — 0.81 ± 0.07, in the vicinity — 0.65 ± 0.01. One patient (5 %) had periodic light scattering circles (halo) and one patient (5 %) — had glare. There were no difficulties with driving in any of the patients. Conclusions. The AcrySof IQ Vivity IOL will provide improved visual acuity at all distances. Some patients will need to use additional spectacle correction, for near distance. 85 % patients rated the results as «excellent», 15 % — «good».
