Clinical results with a multifocal intraocular lens with a novel optical design

Abstract

Background To evaluate the optical performance and safety of a new multifocal lens with a novel optical design featuring two additional foci (or intensifiers) in patients with cataract and presbyopia. Methods In this single-center, non-randomized prospective observational study, 31 patients underwent implantation of the new multifocal IOL between March 2020 and November 2021 in a tertiary clinical center in Buenos Aires and Ramos Mejia, Argentina. Postoperative examinations with an emphasis on uncorrected as well as corrected visual acuity for distance and near vision and over two different intermediate (80 cm and 60 cm) distances were performed over the 3 postoperative months. Results Of the 31 patients who underwent implantation of the new IOL, 30 had a bilateral operation (a total of 61 eyes). At 3 months, all 61 eyes had an uncorrected distance visual acuity of at least 0.15 logMAR ; 57 eyes (93%) had an uncorrected distance visual acuity (UCDVA) of 0.1 log MAR and 27 eyes (44%) an UCDVA of 0.0 logMAR. At a distance of 80 centimeter, 60 eyes (98%) had an uncorrected intermediate visual acuity (UCIVA) of at least 0.1 log MAR and 48 eyes (79%) an UCIVA of 0.0 logMAR. Conclusion The new multifocal IOL with a novel optical concept (5 foci) showed an extensive range of vision, particularly for intermediate and near distances, in patients undergoing cataract surgery. Uncorrected visual acuity over all tested distances, monocularly and binocularly, was excellent, spectacle-independence and patient satisfaction was high.
