目的：探讨角膜塑型术后眼的前房深度(ACD)、晶状体厚度(LT)、眼轴长度(AL)的变化。
方法：对进行角膜塑型镜治疗的120例120眼进行了前瞻性临床研究，将角膜塑形术术前及术后1a的超声检查结果进行比较。
结果：角膜塑型镜治疗1a后，LT较治疗前增厚，其中低度近视组增厚0.14mm，差异有显著的统计学意义(P<0.01)。中高度近视组增厚0.05mm，差异有统计学意义(P<0.05)。前房深度﹑眼轴长度的差异没有统计学意义(P>0.05)。
结论：角膜塑型术后，存在着晶状体屈光力的改变。调节因素可能参与着角膜塑型镜延缓近视发展的机制。

[Abstract]
AIM: To discuss the change of anterior chamber depth(ACD), lens thickness(LT)and axial length(AL)for following orthokeratology.
METHODS:Orthokeratology was performed for 120 patients(120 eyes), and conducted a prospective clinical study. The ultrasound examination results were compared before and after 1a of orthokeratology.
RESULTS: The LT value increased by 0.14mm in the group of low and moderate myopia(P<0.01)and 0.05mm in the group of moderate and high myopia, indicating a statistically significant difference. No significant difference was found in ACD value and AL value following orthokeratology(P>0.05).
CONCLUSION: Crystalline lens power is changed following orthokeratology. Accommodation factor may be the possible mode of action of orthokeratology in reducing myopic progression.
