Beam-Shaping Extended Depth of Focus Intraocular Lens: Optical Assessment With Corneas of Increasing Spherical Aberration Madrid Costa, David Fernández Vega-Cueto, Luis Azor-Morón, Juan Antonio Vega Lerin, Fidel Millán García-Varela, María Sagrario Alfonso, José F. PURPOSE:To assess the optical quality and halo formation of a beam-shaping extended depth-of-focus (EDOF) intraocular lens (IOL) (AcrySof IQ Vivity; Alcon Laboratories, Inc) with corneas of long-range spherical aberration (SA) such as those resulting from myopic laser ablations. 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. 2023-06-22T12:38:40Z 2023-06-22T12:38:40Z 2023-06-22T12:38:40Z 2023-02-01 journal article https://hdl.handle.net/20.500.14352/72980 1081-597X 10.3928/1081597X-20221215-02 eng info:eu-repo/grantAgreement/AEI/Plan Estatal de Investigación Científica y Técnica y de Innovación 2017-2020/PID2020-114582RB-I00/ES/IMPLANTES OPTICOS INTRAOCULARES CORRECTORES DE LA PRESBICIA PARA UNA COMPENSACION VISUAL PERSONALIZADA/ Madrid-Costa D, Fernández-Vega-Cueto L, Azor-Morón JA, Vega F, Millán MS, Alfonso JF.
