Fig. 2From: Effect of short-term orthokeratology lens or ordinary frame glasses wear on corneal thickness, corneal endothelial cells and vision correction in adolescents with low to moderate myopiaChanges of corneal curvature, intraocular pressure and axial length. a: Compared with the control group, the corneal curvature in the experimental group decreased significantly at the 3rd, 6th and 12th months, ***p < 0.0001. b: There was no statistical difference in intraocular pressure between the two groups at each time point (all p > 0.05). c: The axial length at the 6th and 12th months in the control group was significantly higher than that in the experimental group, **p < 0.01, ***p < 0.001Back to article page
