Fig. 4From: Long-term follow-up of changes in ocular biometric parameters in orthokeratology lens wearers with relatively large-scale axial length reductionThe trend of ocular parameters over one year of Ortho-K treatment in the AL reduction and AL elongation groups. a Central corneal thickness (CCT); b Anterior chamber depth (ACD); c Crystalline lens thickness (CLT); d Vitreous chamber depth (VCD); e Axial length (AL). Data are expressed as the means and standard error of the mean. Unpaired t-test; *P < 0.05, **P < 0.01 indicate significant differences between the different groupsBack to article page
