Instantaneous modulus and equilibrium modulus of stress relaxation of ppSCl in axial direction (MPa, Inst: instantaneous modulus; Equl: equilibrium modulus).

Modulus of scleral stress relaxation of each scleral trip was measured for 3 times repeatedly. Paired-samples test was applied in the intergroup comparison in each quadrant; ANOVA method and post hoc test (LSD, Tukey HSD) were applied in the intragroup comparison in each group ^#Instantaneous relaxation modulus of each quadrant in each group, equilibrium relaxation modulus of each quadrant in the experimental group had no significantly different (). Equilibrium relaxation modulus of each quadrant had significant difference in the control group (). The instantaneous and equilibrium relaxation modulus of each quadrant were higher in the experimental group than that in the control group, with significant difference ()
