Measured results were presented as Mean ± Standard Deviation [95% confidence interval], except IOP of PAC/APCG group and total participants as Median (Minimum, Maximum) for their abnormal distribution.
IOP intraocular pressure, PD pupil diameter, ACD anterior chamber depth, LT lens thickness, CCT central corneal thickness, WTW white to white, K keratometry, AL axial length, LT/AL lens thickness/axial length.
P1: Significance of difference among three time points in total. Bold values indicated significant differences based on p value.
P2: Significance of changing pattern between groups. Bold values indicated significant differences based on p value.
P3: Significance of difference among three time points in group PACS. Bold values indicated significant differences based on p value.
P4: Significance of difference among three time points in group PAC/PACG. Bold values indicated significant differences based on p value.
*Indicated p < 0.05, while **indicated p < 0.01 for measurements after intervention compared with that measured at baseline.
#Indicated p < 0.05 and ##indicated p < 0.01 when measurements compared between the two groups at each time point.
фIndicated p < 0.05 for measurements after LPI compared to that measured under miosis.
aCompared using paired samples T-test for PACS group, and related samples Wilcoxon signed rank test for PAC/PACG group for its non-normal distribution.
