METHODS:The optical quality of the EDOF IOL and a reference monofocal IOL was evaluated with three corneas (A, B, and C, with SA =+0.135, +0.290, +0.540 µm, respectively, for a 5.15-mm pupil at the IOL plane). The through-focus modulation transfer function area (MTFa) curves were obtained between −5.00 and +2.00 diopters (D) defocus range. The halo was also assessed with the three corneas. RESULTS:Through-focus MTFa curves for a 4.5-mm IOL pupil showed a slight decrease in the maximum MTFa value provided by the EDOF IOL compared to the monofocal IOL in the three corneal situations (A: 45.9 vs 38.6 units; B: 41.1 vs 33.1 units, and C: 26.9 vs 23.8 units). For the 3.0-mm pupil, the EDOF IOL also had lower maximum MTFa than the monofocal IOL; however, the depth-of-focus increased to −2.20 D. With corneas A and B, the halo induced was of low energy with both IOLs. With cornea C, the EDOF IOL created a much larger and intense halo. CONCLUSIONS:The EDOF IOL provided a good distance optical performance and an extended range of focus of approximately 2.00 D, with a halo of low intensity when evaluated with a corneal SA similar to the one induced by a low to moderate myopic ablation. With a high myopic ablation, the halo induced would be of considerable size and energy.engjournal articlehttps://doi.org/10.3928/1081597X-20221215-02https://journals.healio.com/doi/10.3928/1081597X-20221215-02restricted access617.7-089.243681.73612.844Intraocular lensAberrationSpherical aberrationCorneaLaser ablationsOptical qualityIOLsÓptica y optometríaÓptica oftálmicaMateriales ópticos2209 Óptica2209.14 Propiedad ópticas de los sólidos
