Purpose: comparative analysis of the results of implantation of bifocal refractive-difractive IOLs and new trifocal single-piece aspherical difractive IOLs. Material and Methods. A prospective open study included 193 patients (291 eyes) with presbyopia. The average age of patients was 58.4±11.3 years. Group I consisted of 71 patients (108 eyes) with implantation of the AcrySof PanOptix trifocal IOL; Group II — 122 patients (183 eyes) with the AcriSof Restor bifocal IOL with addidation 3 Dioptr. Results. After 6 months of follow-up in group I, an increase in UCNVA from 0.2±0.09 to 0.85±0.17, an UCFVA from 0.2±0.07 to 0.78±0.13, and a UCIVA from 0.3±0.1 to 0.84±0.2, BCNVA from 0.58±0.24 to 0.98±0.21, BCFVA from 0.68±0.26 to 1±0.1 and BCIVA with 0.59±0.28 to 0.95±0.18 (p<0.05 in all cases). In group II, signifcantly lower values of UCNVA (0.62±0.09), UCIVA (0.31±0.14) and BCIVA (0.6±0.19) were observed when compared with group I (p<0.05). In all groups, a decrease in the spherical and cylindrical component of refraction was observed. Level of contrast sensitivity after implantation of the AcrySof Restor was higher for all frequencies. According to the results of the survey on a scale of VF-14 in group I, the average value was 97.9±1.2 points, and in group II — 80.1±6.4 (p<0.05). Conclusion. In this paper an advantage of a new trifocal IOL for vision correction at an average distance under various lighting conditions is shown, as well as the best indicators of vision quality on the VF-14 scale.
