Universidad de Zaragoza (orcid)0000-0002-9068-7728 On the Relationship between Corneal Biomechanics, Macrostructure, and Optical Properties 2021 Access copy available to the general public Unrestricted Optical properties of the cornea are responsible for correct vision; the ultrastructure allows optical transparency, and the biomechanical properties govern the shape, elasticity, or stiffness of the cornea, affecting ocular integrity and intraocular pressure. Therefore, the optical aberrations, corneal transparency, structure, and biomechanics play a fundamental role in the optical quality of human vision, ocular health, and refractive surgery outcomes. However, the inter-relationships of those properties are not yet reported at a macroscopic scale within the hierarchical structure of the cornea. This work explores the relationships between the biomechanics, structure, and optical properties (corneal aberrations and optical density) at a macro-structural level of the cornea through dual Placido-Scheimpflug imaging and air-puff tonometry systems in a healthy young adult population. Results showed correlation between optical transparency, corneal macrostructure, and biomechanics, whereas corneal aberrations and in particular spherical terms remained independent. A compensation mechanism for the spherical aberration is proposed through corneal shape and biomechanics. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 0.728 2021 Computer Graphics and Computer-Aided Design 2021 Q2 Radiology, Nuclear Medicine and Imaging 2021 Q2 Computer Vision and Pattern Recognition 2021 Q2 4.8 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Marcellán, María Concepción Universidad de Zaragoza (orcid)0000-0002-7516-3029 Remón, Laura Universidad de Zaragoza (orcid)0000-0002-3979-4528 2002 647 Universidad de Zaragoza Dpto.
