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.
Key Questions
1. What is a multifocal IOL, and how does it work?
A multifocal intraocular lens (IOL) is an artificial lens implanted during cataract surgery that provides multiple focal points for vision at various distances, helping to reduce or eliminate the need for glasses or contact lenses after surgery.
2. What are the benefits of the new multifocal IOL with five foci?
The new multifocal IOL with five foci offers a wide range of visual acuity, particularly improving intermediate and near vision, providing excellent uncorrected visual acuity and high patient satisfaction.
3. How does the new multifocal IOL compare to traditional IOLs?
The new multifocal IOL, with its innovative design featuring five foci, provides better visual acuity at different distances, especially at intermediate and near ranges, compared to traditional single-focus IOLs.
4. How does the IOL implantation affect post-surgery outcomes?
Post-surgery, the new multifocal IOL improves uncorrected distance visual acuity, intermediate visual acuity, and near vision, leading to high spectacle independence and patient satisfaction.
5. What are the potential complications of multifocal IOL implantation?
Potential complications include glare, halos, and difficulty with contrast sensitivity, but the new multifocal IOL demonstrated low complication rates in this study.
