摘　　要：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。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.
