Note. P-Dist: distance between the pupil center and the coaxially sighted corneal light reflex. （the paired t-tests were used to detect differences between the 50% group and the 100% group; correlations with different P-Dist were determined using the unpaired t-test). There were 130 eyes in small-angle k group (62 eyes in the 50% group and 68 eyes in the 100% group) and 124 eyes in large-angle k group (65 eyes in the 50% group and 59 eyes in the 100% group).
