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.<h4>Results</h4>The β parameter (homogeneity) increased by 5% after wearing both CL materialsOphthalmic & physiological optics : the journal of the British College of Ophthalmic Opticians (Optometrists)35-45https://www.ebi.ac.uk/biostudies/studies/S-EPMC10099478biostudies-literatureCorneal tissue changes following short-term soft contact lens wear of different materials.PMC10099478Remon LConsejo ATrillo-Moreno IfalseCorneal tissue changes following short-term soft contact lens wear of different materials.<h4>Purpose</h4>To study the effect of different soft contact lens (CL) materials during short-term wear on corneal tissue.<h4>Methods</h4>Twenty-two healthy participants wore both silicone hydrogel (MyDay, CooperVision) and hydrogel soft CLs (Biomedics 1 day extra, CooperVision) for 8 h per lens.
