BINOCULAR IMPLANTATION OF NEW DIFFRACTIVE TRIFOCAL INTRAOCULAR LENS FOR PRESBYOPIA CORRECTION

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 <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.
