目的:探讨配戴软性角膜接触镜对中央角膜厚度的影响。方法:应用超声角膜测厚仪检测中央角膜厚度,在我院近视患者中随机抽取配戴软性角膜接触镜者及不戴镜者各100例200眼,做统计分析。再在近视患者中按戴镜时间<1a,1～3a,3～5a,5～7a,≥7a分组,每组随机抽取60例120眼,做统计分析。结果:配戴软性角膜接触镜者与不戴镜者的角膜厚度比较,差异有统计学意义(P<0.05)。戴镜时间<1a,1～3a,3～5a,5～7a者的角膜厚度比较,差异有统计学意义(P<0.05)。结论:配戴软性角膜接触镜者平均中央角膜厚度薄于不戴角膜接触镜者,并且配戴软性角膜接触镜的时间越长中央角膜厚度越薄。

·AIM:To investigate the effect of soft corneal contact lens on central corneal thickness.·METHODS:Central corneal thickness was detected with ultrasonic corneal pachymetry,myopic patients who wore soft contact lens and who did not wear soft contact lens of 100 cases 200 eyes were randomly selected in our hospital for statistical analysis.Then according to the wearing time <1 year,1-3,3-5,5-7,≥ 7 years they were grouped,60 patients(120 eyes)were randomly selected from each group to do statistical analysis.·RESULTS:Corneal thickness of those who wore soft contact lens being compared with those who did not wear soft contact lens,the difference was statistically significant(P<0.05).For comparison of corneal thickness with wearing time <1 year,1-3,3-5,5-7,≥ 7 years,the difference was statistically significant(P<0.05).·CONCLUSION:The average central corneal thickness of those who wear soft contact lens is thinner than those who do not wear contact lens,the longer they wear soft contact lens,the thinner their central corneal thickness is.·
