Clinical and functional results of bifocal and trifocal intraocular lenses implantation: a comparative analysis

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
