Clinical Results Of A New Advanced Monofocal Iol

Enhanced monofocal IOL technology is continuously evolving in order to achieve more spectacle independence. Unlike multifocal IOLs, the advanced monofocal IOLs create a single elongated focal point rather than several foci and it is known that elderly patients more often require a dynamic change in focus for intermediate vision.
The aim of this paper is to investigate the clinical results after the implantation of a new enhanced monofocal intraocular lens (IOL), Evolux® (SIFI spa), in a single centre in Italy.

This is a single center prospective study including patients affected by cataract with no ocular comorbidities and corneal astigmatism less than 0.75 diopters(D).
Twenty-five eyes of 20 patients were recruited for the implation of Evolux® IOL (SIFI spa) performing standard cataract procedure. The main outcome measures were monocular and binocular uncorrected and corrected visual acuity at distance (4 m), intermediate (60 cm) and near (40 cm). Binocular defocus curve, binocular contrast sensitivity, aberrometric study, halo and glare perception were also evaluated. Patients-reported visual function was inquired by Catquest-9SF. Study examination were performed preoperatively, 1 week, 1 month, 3 months and 6 months after cataract surgery.

This study included 25 eyes of 20 patients (10 male, 10 female) with a mean age of 68 ± 8 years. No intra-operative or post-operative complications were reported. Best-corrected visual acuity improved from 0.5 ± 0.2 LogMAR to 0.0 ± 0.0 LogMAR (p < 0.01). Refractive outcome was excellent for distance and intermediate vision, worse for near vision where spherical addition was usually required. Most patients were not at all bothered by halos and glare, with no reported severe visual disturbances. No significant reduction in contrast sensitivity was reported. Follow-up visits will be completed in August 2023. Therefore final results will be presented at the ESCRS in Amsterdam.

In patients undergoing cataract surgery, Evolux® IOL (SIFI spa) demonstrated good intermediate and distance vision performance without significant visual disturbances. The final conclusions of the study will be presented at the meeting.
