Comparison of higher-order aberrations between different P-Dist groups at 3 months (the pupil diameter is 5.0 mm).

100% group	0.24 ± 0.15	0.30 ± 0.17	−1.434	0.142
t value	−0.516	−0.186
value	0.234	0.258

Note. (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 the large-angle k group (65 eyes in the 50% group and 59 eyes in the 100% group).
