A cross-sectional study was carried out in Torrecárdenas Hospital, Almería, Spain, between February 2018 and July 2019. It included 250 keratoconus patients. Two groups were created according to a grading system of V.L. based on RETICS (Red Temática de Investigación Cooperativa en Salud) classification: keratoconus patients with no V.L. (best spectacle-corrected visual acuity (BSCVA) ≤ 0.05 logMAR) and keratoconus patients with V.L. (BSCVA > 0.05 logMAR). Correlations and a binary logistic regression were established. V.L. was correlated with maximum curvature (r = 0.649, p  0.05 logMAR). Correlations and a binary logistic regression were established. V.L. was correlated with maximum curvature (r = 0.649, p enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/AdultArea Under CurveCorneal TopographyCorneal Wavefront AberrationCross-Sectional StudiesFemaleHumansKeratoconusMaleMiddle AgedROC CurveRefraction, OcularRegression AnalysisSpainVision DisordersVisual AcuityYoung Adultresearch article33168906open access10.1038/s41598-020-76489-12045-2322PMC7652865https://www.nature.com/articles/s41598-020-76489-1.pdfhttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC7652865/pdf
