| 目的：通过人工角膜曲率计、自动角膜曲率计和角膜地形图仪三种不同仪器测量角膜曲率的对比研究，了解此类仪器在白内障术前测算人工晶体屈光度中提供K值的精确性。方法：应用三种仪器对102例135眼测量角膜曲率，分别计算人工晶体屈光度，然后进行统计学分析。结果：三种仪器测得的角膜曲率最大值、最小值、平均曲率和人工晶体屈光度计算结果略有差异，但经统计学分析差异无统计学意义（P >0.05）。 结论：三种仪器测量的角膜曲率值均可用于人工晶体屈光度的计算，且数据准确可靠，但对于角膜过平、过陡者，则推荐使用角膜地形图仪。 |

| Objective:To compare the corneal curvature measured in determining the power of intraocular lens by three kind devices, keratometer, auto-refractomer and corneal topographer．Methods:The corneal curvature of 135 eyes of 102 cases with cataract were measured using keratometer，auto-refractomer and corneal topographer．corneal curvature and the calculated power of intraocular lens have been analyzed using SPSS．Results:There were no statistically sighnificant difference among the measuring data from 3 different devices on the items of maximum，minimum and mean values of corneal curvature．Also there is no significant difference in calculated degrees of intraocular lens．Conclusions:All three methods are effective in measuring central corneal curvature and are reliable in calculating the power of intraocular lens．Corneal topographer is more reliable for the patients cornea was too steep or flat. |
