Abstract:
coefficient of variation, corneal endothelium hexagonal cell ratio, anterior corneal surface curvature ratio of horizontal(HK) and vertical curvature(VK) were not statistically significant before and after wearing for 6mo, 1, and 2a (P > 0. 05). The uncorrected visual acuity increased significantly, and the diopter decreased significantly after their wearing (P<0.05). There was no significant difference in axial length after wearing OK lens for 6mo,1,and 2a (P>0.05). CONCLUSION: The orthokeratology lenses can significantly increase uncorrected visual acuity and improve refractive power for juvenile myopia without severe corneal or conjunctival complications occurred, which has little influence on corneal endothelial cells and corneal thickness with a certain degree of safety.
