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 <0.05). The increase in BCNVA was from 0.49 ± 0.23 to 0.99 ± 0.07, BCIVA from 0.44 ± 0.27 before and 0.96 ± 0.11 and BCDVA from 0.58 ± 0.25 to 1.0 ± 0.04 (p <0.05). The greatest visual acuity (0.0 logMAR for OU) was noted with a defocus of 0, which corresponds to the point of clear vision in the distance. At -1.0 D (the point of clear vision at an average distance) and -2.5 D (the point of clear vision near), a high visual acuity (0.04 and 0.09 logMAR, respectively) was noted, which indicates a good vision correction in all investigated distances. The frequency of achieving SE in the range ± 0.5 D was 92.7%. The primary endpoint of the study (BCDVA = 1.0) in the long-term follow-up period was 95.1%. In all cases, high patient satisfaction and a low incidence of undesirable side effects were noted (glare, halo, difficulty in driving). Conclusion. Implantation of the trifocal IOL AT LISA tri 839MP leads to a good level of functional vision restoration at near, average and far distance after cataract surgery and clear lens removal.AT Lisa trifocalcataractmultifocal IOLtrifocal IOLpresbyopiaAT Lisa trifocalкатарактамультифокальные ИОЛтрифокальные ИОЛпресбиопия[Воскресенская А.А., Поздеева Н.А., Паштаев Н.П., Батьков Е.Н., Треушников В.М., Чередник В.И.
