There were no statistically significant differences in peripheral
J0 and
J45 between the two groups at baseline (at all eccentricities,
P > 0.05). After 2 years, peripheral
J0 showed significant positive shifts at 10T and 20T, with the changes of 0.25 ± 0.33 D (
P < 0.0001) and 0.25 ± 0.47 D (
P < 0.0001), respectively, in the DIMS group. In the SV group, significant positive shifts were observed at 10T (mean difference: 0.29 ± 0.28 D,
P < 0.0001), 20T (mean difference: 0.54 ± 0.50 D,
P < 0.0001), 20N (mean difference: 0.17 ± 0.38,
P < 0.0001), and 30N (mean difference: 0.16 ± 0.47,
P = 0.004). There were no changes in peripheral
J45 within the DIMS or SV groups (at all eccentricities,
P > 0.05). There was no significant difference of peripheral
J0 between two groups after 2 years nor in peripheral
J45 over 2 years after Bonferroni correction (
P > 0.008;
