AX axis, BCEA bivariate contour ellipse area, BCVA best corrected visual acuity, CYL cylinder, LogMAR Logarithm of the Minimum Angle of Resolution, OD right eye, OS left eye, PRL preferred retinal locus, SPH sphere. The median PRL eccentricity was 0.45° from the foveal centre (IQR 0.18°, range 0.05°–0.99°), median 63% BCEA was 0.3 deg2 (IQR 0.3 deg2, range 0.1 deg2–2.2 deg2), the median retinal sensitivity was 27.2 dB (IQR 1.2 dB, range 25.7–29.0 dB), and the median PRL sensitivity was 29.2 dB (IQR 1.9 dB, range 26.5–31.3 dB).
