| 摘 要： | 目的探讨手持式自动角膜曲率计测量角膜屈光度的准确性及临床应用。方法采用天津索维SW-100型手持式自动角膜曲率计及日本TOPCON OM-4型手动角膜曲率计分别对门诊60例118眼进行角膜屈光度测量。结果2种角膜曲率计在平均角膜屈光度最大值K1、平均角膜屈光度最小值K2、平均角膜屈光度（K1＋K2）／2及平均角膜散光度K1-K2上无显著差异，但散光轴向上差异有显著性。结论手持式自动角膜曲率计在测量角膜屈光度上与传统手动角膜曲率计无显著差异，可广泛应用于角膜屈光度的测量。

| Abstract: | Objective To investigate the accuracy of hand-held auto photokeratometer in measuring corneal diopter and its clinical application.Methods The corneal diopter in 60 cases(118 eyes) were measured by hand-held auto photokeratometer (SW-100 Suoer,TianJin) and manual keratometer (OM-4 Topcon,Japan),the results were compared.Results There was no significant difference in the highest(k1) and smallest(k2) value of mean corneal diopter,mean corneal astigmatism obtained from two photokeratometer(P>0.05),but there was significant difference in axes of astigmatism between two photokeratometer(P<0.05).Conclusion The hand-held auto photokeratometer is similar to manual keratometer in clinical value,and can be used in measuring corneal diopter. |
