Clinical Outcomes and Patient Satisfaction with the ELON Extended Depth-of-Focus Intraocular Lens: A Prospective Comparative Study

Abstract: PURPOSE: To evaluate patient-reported satisfaction, visual performance, and refractive predictability of the ELON extended depth-of-focus (EDoF) intraocular lens (IOL), as compared to monofocal IOLs in a Swiss single-centre clinical cohort. Abstract: METHODS: This was an observational cohort study of 32 patients who underwent cataract surgery with implantation of the ELON IOL. A matched monofocal control group was used to enable comparison. Patient-reported satisfaction included visual performance, expectation fulfillment, and satisfaction. Secondary outcomes included postoperative refractive error, best corrected distance visual acuity (BCVA), and reported incidence of halos/glare. Abstract: RESULTS: The ELON group reported high visual performance (mean 4.19/5), expectations met (mean 4.45/5), and overall satisfaction (mean 4.94/5). Compared to the adapted monofocal group (visual performance 4.05/5, expectations 4.18/5), ELON patients reported equivalent or superior scores across all measures. Halos or glare were reported in 9.4% of ELON patients. Refractive predictability was high, with 90.6% of eyes within ± 0.50 D spherical equivalent. Mean BCVA was logMAR 0.04. Abstract: CONCLUSION: The ELON IOL provides great patient satisfaction, strong refractive predictability, and minimal dysphotopsia. These results suggest that ELON is a promising alternative to monofocal IOLs for patients desiring enhanced functional vision with a continuous range of focus.
