Abstract
Aim. Evaluation of the visual and functional results of bilateral implantation of the diffractive trifocal intraocular lens (IOL), the incidence of adverse optical phenomena and the degree of patient satisfaction. Methods. A prospective, open-label study included 82 patients (164 eyes) with presbyopia who underwent cataract phacoemulsification (n = 128) or refractive lensectomy (n = 36) with bilateral implantation of a new multifocal IOL AT LISA tri 839MP. The mean age of the patients was 61.2 ± 11.8 (32-84) years. The period of observation of patients was from 6 to 36 (18.3 ± 3.9) months. Results. After 1 year of follow-up, the increase in UCNVA was observed from 0.19 ± 0.17 to 0.89 ± 0.21, UCIVA from 0.18 ± 0.20 to 0.78 ± 0.17, UCDVA from 0.26 ± 0, 23 to 0.9 ± 0.12 (p
