AL axial length, SER spherical equivalent of refractive error, ACD anterior chamber depth, SFChT subfoveal choroidal thickness, CCP central cornea power, PBM group photobiomodulation therapy group, Control group single-vision spectacles group. The P values were determined by the independent samples.
at-test of the two groups, with the exception of gender, for which the bChi-square test was used.
