Methods: Twenty-two healthy participants wore both silicone hydrogel (MyDay, CooperVision) and hydrogel soft CLs (Biomedics 1 day extra, CooperVision) for 8 h per lens. In each session, Scheimpflug images were captured before and immediately after CL removal. Images were analysed using the densitometry distribution analysis, a technique from which two parameters, α (corneal transparency) and β (corneal homogeneity), were estimated. In addition, the central corneal thickness changes after CL wear and the influence of the CL material on corneal transparency were evaluated. Results: The β parameter (homogeneity) increased by 5% after wearing both CL materials (paired t-test, p < 0.001). However, the α parameter (transparency) only increased in half of the participants. No material was found to be more determinant in causing the corneal densitometry changes. Statistically significant but not clinically relevant changes in corneal thickness were observed. Conclusions: Biomarkers of corneal tissue integrity (α and β) were affected by short-term soft contact lens wear. The observed changes in corneal transparency and homogeneity were not clinically relevant but support the importance of participant-material biocompatibility. info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.8 2023 OPHTHALMOLOGY 24 / 95 = 0.253 2023 Q2 T1 1.162 2023 Ophthalmology 2023 Q1 Sensory Systems 2023 Q1 Optometry 2023 Q1 5.1 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Trillo Moreno, Irene Remon, Laura Universidad de Zaragoza (orcid)0000-0002-3979-4528 2002 385 Universidad de Zaragoza Dpto.
