Data distribution. The histograms show the cross-sectional distribution of age (A), VRQoL composite score (B), near vision subscore (C), distant vision subscore (D), binocular reading acuity (E), and BCVA of the better eye (F). The solid vertical line denotes the median value. Please note, the Radner reading acuity (B) score exhibits a marked floor effect and that, due to the design of the questionnaire, some values in C and D could not be attained.
