Purpose

To analyze the optical performance of a novel non-diffractive intraocular lens (IOL) and to compare it with a clinically established diffractive trifocal IOL under different pupil apertures and defocus

Setting

Clínica Rementería, Madrid, Spain and Department of Physics and Astronomy, University of Florence, Italy

Methods

Using a PMTF optical bench (LAMDA-X Ophthalmics, Belgium), two presbyopia-correcting IOL models were analyzed. The reference diffractive trifocal IOL was the Clareon® PanOptix® while the novel non-diffractive IOL was the RayOne® Galaxy®. Through-focus modulation transfer function (MTF) measurements were obtained across four pupil apertures (2.0, 3.0, 3.75, and 4.5 mm), and halo intensity was quantified via analysis of the point spread function (PSF) tail

Results

The PanOptix IOL demonstrated three consistent focal points across all apertures. The Galaxy IOL maintained high optical quality at distance focus for large pupil sizes; however, with smaller pupils, a myopic shift of the main peak (≈0.75 D) was observed, enhancing intermediate and near visual performance. Additionally, the Galaxy IOL induced a lower-intensity halo profile compared with the PanOptix IOL

Conclusions

The diffractive PanOptix IOL maintained consistent optical performance across pupil sizes; in contrast, the novel Galaxy IOL exhibited pupil-dependent optical behavior, transitioning from optimal distance performance at larger pupils to enhanced intermediate and near performance at smaller apertures, while producing lower halo levels
