Clinical and Aberrometric Evaluation of a New Refractive Intraocular Lens with Central Extended Depth-of-Focus (Lucidis©)


Purpose: To assess the visual performance of a new refractive/extended depth of focus (EDOF) hybrid intraocular lens

Methods: This is a monocentric, retrospective study of 94 patients (158 eyes), carried out in a tertiary-care glaucoma
research center. All patients underwent implantation of the Lucidis (Swiss Advanced Vision, SAV-IOL SA, Neuchâtel,
Switzerland) IOL during cataract surgery. Near, intermediate and far best corrected visual acuity and uncorrected visual
acuity were collected at baseline and 3-month postoperatively. Adverse events, contrast sensitivity, optical aberrations,
subjective satisfaction and spectacle independence were also analyzed at 3-month.

Results: At 3-month post-operatively, mean photopic uncorrected monocular distance, intermediate and near Snellen visual
acuity were 0.2 logMAR (~20/32), 0.07 logMAR (~20/23) and 0.15 logMAR (~20/28) respectively. Mean best corrected
Snellen visual acuity was 0.1 logMAR (~20/25) for distance and 0.03 logMAR (~20/21) for near vision.

Conclusion: The Lucidis IOL demonstrates good safety profile, with an acceptably low complication rate. The uncorrected
visual performances of this new optical design are inferior to those of other EDOF IOLs for distance-vision, but achieve
better results in intermediate and near vision, with consistently near-normal contrast sensitivities. Interestingly, selfreported spectacle independence and subjective patient satisfaction are high for all distances.
