The feasibility of multifocal intraocular lenses in cataract surgery in the elderly

Purpose: to evaluate the effect of changes in pupil size on visual acuity after implantation of multifocal intraocular lenses in patients with senile cataract, to assess the influence of multifocal intraocular lenses on the quality of life of elderly people. Material and Methods. 50 eyes of 50 elderly patients (32 men, 18 women aged 48–81 years) after cataract surgery in 2019–2021 were retrospectively examined. Preoperative and postoperative pupil sizes were measured using an Oasis pupillometer. We assessed the quality of life using a special questionnaire NEI–VFQ-25 (National Eye Institute Visual Function Questionnaire, version 2000), before and one month after the operation. Results. The average preoperative pupil size decreased to 4.1±0.9 from 4.9±1.0 mm during the first postoperative month (р=0.05). In the total score for the quality of life the patients had an increase after surgery from 49.5±15.1 to 64.7±14.4 points (р<0.05). Conclusion. The change in the pupil size after surgery does not affect or only slightly affects the clinical results of implantation of multifocal intraocular lenses (MF-IOLs). Multifocal intraocular lenses allow elderly people to improve their quality of life.
