PURPOSE: To evaluate the clinical outcomes of a new extended depth of focus (EDOF) intraocular lens (IOL) in patients with cataracts.
SETTING: Qvision, Department of Ophthalmology, VITHAS Almería Hospital, Almería, Spain.
DESIGN: Retrospective observational.
METHODS: Data were retrospectively reviewed for a cohort of 51 consecutively operated patients with cataract implanted with the ELON IOL and followed over a 12-month period. The variables collected for analysis included visual acuities (VAs) at various distances (far, intermediate, and near), light distortion index (LDI), defocus curves, and prediction error. In addition, patient-reported outcomes were gathered to assess spectacle dependence, satisfaction with vision, positive dysphotopsia, difficulties in daily activities, and patients' willingness to undergo the same IOL procedure again.
RESULTS: Monocular data for efficacy were available for 36 patients at the 3-month follow-up and 23 patients at the 12-month follow-up. Median monocular distance-corrected VAs were 0 logMAR, 0.1 logMAR, and 0.3 logMAR at 4 m, 66 cm, and 40 cm, respectively, at 3 months and 12 months. Correlations between VAs and pupil diameter were found but only at near for binocular uncorrected (ρ = 0.38, P = .02) and monocular distance corrected (ρ = 0.31, P = .07). The median LDI reduced up to 9% at 12 months. No significant differences were found between follow-up visits for VAs and LDI ( P > .05); however, satisfaction, positive dysphotopsia, and willingness to undergo the same IOL procedure significantly improved from 3 to 12 months ( P < .05).
CONCLUSIONS: The ELON IOL extended the depth of field from far to intermediate distances, with some patients with smaller pupil diameters also achieving near vision restoration.
