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

(2024)

This study examined the optical performance and safety of a newly designed multifocal intraocular lens (IOL) with five focal points (two additional "intensifiers") for cataract and presbyopia management. Conducted in Buenos Aires and Ramos Mejia, Argentina, the prospective, non-randomized observational study included 31 patients (61 eyes) who received bilateral implantation between March 2020 and November 2021. At the 3-month follow-up, all eyes achieved an uncorrected distance visual acuity (UCDVA) of at least 0.15 logMAR, with 93% achieving 0.1 logMAR and 44% achieving 0.0 logMAR. For intermediate vision at 80 cm, 98% of eyes achieved at least 0.1 logMAR, and 79% reached 0.0 logMAR. The results highlight the new multifocal IOL’s efficacy, particularly for intermediate and near vision, with high rates of spectacle independence and patient satisfaction.

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 at a tertiary clinical center in Buenos Aires and Ramos Mejia, Argentina. Postoperative examinations with emphasis on uncorrected and corrected visual acuity at distance and near and at two different intermediate distances (80 cm and 60 cm) were performed during the 3
postoperative months.

Results:

Of the 31 patients who underwent implantation of the new IOL, 30 underwent bilateral surgery (61 eyes in total). At 3 months, all 61 eyes had an uncorrected distance visual acuity (UCDVA) of at least 0.15 logMAR; 57 eyes (93%) had an uncorrected distance visual acuity (UCDVA) of 0.1 logMAR and 27 eyes (44%) had an UCDVA of 0.0 logMAR. At 80 cm, 60 eyes (98%) had an uncorrected intermediate visual acuity (UCIVA) of at least 0.1 log MAR and 48 eyes (79%) had an UCIVA of 0.0 logMAR.

Conclusion:

The new multifocal IOL with a novel optical concept (5 foci) showed a wide range of visual acuity especially at intermediate and near distances in patients undergoing cataract surgery. Uncorrected visual acuity was excellent at all tested distances, monocularly and binocularly, spectacle independence and patient satisfaction were high.

This ambispective, non-randomized study evaluated the visual performance, safety, and patient satisfaction of the Intensity SL (Hanita Lenses) five-focus pseudophakic intraocular lens (IOL) over a 24-month period. The study included 120 eyes of 60 patients who underwent femtosecond laser-assisted bilateral cataract surgery. At two years postoperatively, patients demonstrated excellent uncorrected visual acuity across far, intermediate, and near distances (binocular UDVA −0.05 ± 0.05 logMAR; UIVA 0.009 ± 0.05; UNVA 0.04 ± 0.06). Visual stability was maintained between the 6- and 24-month follow-ups. Dysphotopsias such as glare and halos were rare and mild. Patient satisfaction was remarkably high, with 95% reporting being "very satisfied" and 100% indicating they would choose the same IOL again. The findings support the long-term visual efficacy and quality-of-life benefits of the Intensity SL IOL.

This study assessed the refractive outcomes, optical performance, and quality of vision in patients implanted with the Intensity Hanita diffractive intraocular lens (IOL). The prospective, observational study included 64 eyes that underwent bilateral cataract surgery with Intensity IOL implantation, with evaluations conducted at 6 months post-surgery. Results indicated that 66% of eyes achieved uncorrected distance visual acuity (UDVA) of 0.10 logMAR or better. The defocus curve showed optimal vision at distance (0.02 ± 0.07 logMAR at 0.0 D) with stable performance through intermediate and near vision ranges (0.11 ± 0.08 logMAR at -1.5 D, 0.12 ± 0.12 logMAR at -2.5 D). Contrast sensitivity remained stable (p ≥ 0.06), and high-order aberrations were low, with a Strehl ratio of 0.12 ± 0.04. Mild halos and glare were reported but did not interfere significantly with daily activities, and the near activity visual questionnaire (NAVQ) indicated high patient satisfaction with near-vision tasks. These findings support the Intensity Hanita IOL’s effectiveness in providing clear vision across all distances through a five-foci distribution design that enhances depth of focus.
