摘要:
 目的　比较配戴软性及硬性角膜接触镜对角膜形态及前房深度的影响。方法　选取屈光不正患者６０例（１２０眼），分别予以配戴软性角膜接触镜（ｓｏｆｔｃｏｎｔａｃｔｌｅｎｓ，ＳＣＬ）及透气性硬性角膜接触镜（ｒｉｇｉｄｇａｓｐｅｒｍｅａｂｌｅｃｏｎｔａｃｔｌｅｎｓ，ＲＧＰＣＬ），其中ＳＣＬ组３０例（６０眼），ＲＧＰＣＬ组３０例（６０眼），ＯｂｓｃａｎⅡ角膜地形图观察戴镜前及戴镜后１ａ、２ａ角膜屈光力、角膜前后表面Ｄｉｆｆ值、中央角膜厚度、前房深度的变化。结果　戴镜前ＲＧＰＣＬ组角膜上下表面屈光力差值为（０．９８±０．４９）Ｄ，戴镜后１ａ为（０．６６±０．４３）Ｄ，戴镜后２ａ为（０．５９±０．３７）Ｄ，均较戴镜前减小（Ｐ＜０．０５）；戴镜后１ａ、２ａ角膜前表面屈光力均较戴镜前降低，差异均有统计学意义（均为Ｐ＜０．０５）。ＳＣＬ组戴镜后１ａ、２ａ角膜前后表面屈光力、Ｉ－Ｓ值、前后表面Ｄｉｆｆ值、前房深度与戴镜前比较，差异均无统计学意义（均为Ｐ＞０．０５）；戴镜前中央角膜厚度为（５４９±２６）μｍ，戴镜后１ａ为（５２７±２９）μｍ，与戴镜前比较差异无统计学意义（Ｐ＞０．０５），戴镜后２ａ为（５０９±３１）μｍ，与戴镜前比较差异有统计学意义（Ｐ＜０．０５）。结论　长期配戴ＲＧＰＣＬ对角膜代谢和功能影响不明显，且能够提供更好的光学矫正效果。
Abstract:
 Objective To evaluate and compare the effects of soft contact lens ( SCL) and rigid gas permeable contact lens ( RGPCL) on corneal topography and anterior chamber depth. Methods One hundred and twenty eyes of 60 contact lens users were divided into two groups :SCL group and RGPCL group,30 cases ( 60 eyes) in each group. The corneal refraction , anterior and posterior corneal surface Diff values . central corneal thickness , anterior chamber depth before wearing CL and I year,2 years after wearing CL were measured and compared. Results The corneal I - S value before wearing RGPCL was ( 0. 98 + 0. 49 ) D ,1 year after wearing RGPCL was ( 0. 66 +0. 43 ) D . and 2 years after wearing RGPCL was ( 0. 59 + 0. 37 ) D. there was statistical difference compared with that before wearing RGPCL ( P < 0. 05 ) . At 2 years after wearing RGPCL , the average refractive power of anterior corneal surface was lower than that before wearing RGPCL ( P < 0. 05 ) . There was no statistical difference in refractive power of anterior and posterior corneal surface. I-S value. anterior and posterior corneal surface Diff values and anterior chamber depth at 2 years after wearing SCL compared with before wearing SCL ( all P > 0. 05 ) ; Central corneal thickness before wearing SCL was (549 +26) ym, at I year after wearing SCL was (527 + 29) ym , there was no statistical difference (P > 0. 05 ) .and at 2 years after wearing SCL was (509 + 31) ym, there was statistical difference (P < 0. 05 ) . Conclusion RGPCL does not change the corneal metabolism and function.and can provide the better corrected refractive effects.
