摘　　要：目的近视眼有极高的发病率,文中通过108例青少年近视患者配戴角膜塑形镜前后的眼压变化,探讨角膜塑形镜对青少年眼压的影响。方法对108例(190只眼)患者配戴角膜塑形镜前后的眼压、屈光度及中央角膜厚度变化进行测量,对结果进行统计学分析。结果 108例青少年近视患者配戴角膜塑形镜前后角膜中央厚度、角膜曲率、屈光度降低(P<0.05)。非接触眼压计(non-contact tonometer,NCT)所测眼压降低(P<0.05),动态轮廓眼压计(dynamic contact tonometer,DCT)所测眼压与戴镜前相比无统计学意义(P>0.05)。结论青少年配戴角膜塑形镜会引起NCT测量数值降低,但不会引起眼压的降低。Objective The incidence of myopia is high in the Chinese population. This study aimed to investigate the intraocu lax pressure （IOP） change before and after orthokeratology lens wear. Methods Using noncontact tonometry （NCT） and dynamic contour tonometry （DCT）, we measured the lOP, diopter and central corneal thickness of 108 eases of myopia in 190 eyes, and statisti cally analyzed the data obtained. Results The central corneal thickness, corneal curvature, diopter and IOP were significantly reduced （ P 〈 0.05 ）, but the lOP measured by DCT showed no statistically significant difference from that before orthokeratology lens wear （ P 〉 0.05）. Conclusion Orthokeratology lens wear does not reduce IOP in adolescents.
