Universidad de Zaragoza Fractal-structured multifocal intraocular lens 2018 Access copy available to the general public Unrestricted In this work, we present a new concept of IOL design inspired by the demonstrated properties of reduced chromatic aberration and extended depth of focus of Fractal zone plates. A detailed description of a proof of concept IOL is provided. The result was numerically characterized, and fabricated by lathe turning. The prototype was tested in vitro using dedicated optical system and software. The theoretical Point Spread Function along the optical axis, computed for several wavelengths, showed that for each wavelength, the IOL produces two main foci surrounded by numerous secondary foci that partially overlap each other for different wavelengths. The result is that both, the near focus and the far focus, have an extended depth of focus under polychromatic illumination. This theoretical prediction was confirmed experimentally by means of the Through-Focus Modulation Transfer Function, measured for different wavelengths. info:eu-repo/grantAgreement/ES/MINECO/DPI2015-71256-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.776 2018 MULTIDISCIPLINARY SCIENCES 23 / 69 = 0.333 2018 Q2 T2 1.1 2018 Agricultural and Biological Sciences (miscellaneous) 2018 Q1 Medicine (miscellaneous) 2018 Q1 Biochemistry, Genetics and Molecular Biology (miscellaneous) 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion García-Delpech, S.
