Abstract Details
Purpose:
Evaluation of the visual and functional results of bilateral implantation of the diffractive trifocal intraocular lens, the incidence of adverse optical phenomena and the degree of patient satisfaction.
Setting:
Eximer eye center, Moscow, Russian Federation.
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, 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). 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). 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 and -2.5 D, a high visual acuity (0.04 and 0.09 logMAR, respectively) was noted.
Conclusions:
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). 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.
