　　目的：探讨角膜塑形镜对角膜前后表面曲率半径和前房深度的影响。方法：用Orbscan-Ⅱ角膜地形图，检查17例31眼配戴角膜塑形镜3个月后角膜前后表面曲率半径和前房深度的变化。结果：配戴角膜塑形镜3个月后所有患者屈光度下降，裸眼视力上升（P<0.001），角膜前表面曲率半径明显改变（P<0.05），后表面曲率半径、前房深度无明显影响（P>0.05）。结论：角膜塑形镜主要通过改变角膜前表面的曲率，压平角膜前表面达到矫正近视的目的，对角膜后表面与前房深度无明显影响。

Objective To find out the affect of orthokeratology lens to the anterior and posterior corneal sur-face and anterior chamber depth.Methods 17 patients ,31eyes, after 3 months orthokeratology wearing, corneal topography examination with Orbscan-Ⅱ,record the changes of the anterior and posterior corneal surface radius and anterior chamber depth.Results After 3 months orthokeratology wearing, the refraction diopter decline, uncor-rected visual acuity increased (P<0.001),the radius of anterior corneal surface change significantly (P<0.05), No significant differences in the radius of posterior corneal surface, and the depth of anterior chamber depth (P>0.05).Conclusion Orthokeratology lens mainly affects the shape of the anterior corneal surface , flatten the anteri-or corneal surface, rather than change of the posterior corneal surface radius and anterior chamber depth to achieve the effect of reducing refraction.
