For group 1 eyes, Pentacam HR images were captured within one hour of SCL removal and after one month of discontinuation. The evaluated indices included curvature, elevation, and pachymetric parameters.Results: Elevation indices and two pachymetric indices (central corneal thickness and thinnest corneal thickness) did not show significant differences, either between the two groups or in group 1 after SCL discontinuation. Some pachymetric indices (average and maximum corneal pachymetry progression indices, and maximum Ambrosio’s relational thickness index) showed statistically significant (P-value < 0.001), yet clinically irrelevant differences. Contrarily, changes in curvature indices were both statistically significant (P-value < 0.001) and clinically relevant.Conclusion: From a clinical point of view, many elevation and pachymetric indices are robust against SCL wear, and can be relied upon for corneal ectasia screening of SCL wearers, even without abstaining from wearing SCLs.Keywords: soft contact lens warpage, Pentacam HR indices, soft contact lens wearers, silicone hydrogel contact lenses, contact lens discontinuationElkitkat RSBadran TAEbeid WMDove Medical Pressarticlesoft contact lens warpagepentacam hr indicessoft contact lens wearerssilicone hydrogel contact lensescontact lens discontinuation.OphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 15, Pp 1573-1581 (2021)
