The study of comparison of corneal diopter measured by corneal keratometer and corneal topographer

角膜曲率计与角膜 地形 图仪测量角膜屈光度的对比研究

The results show that The relativity of Precipitation and macroeconomics topographer is good in time scale .

研究发现，在时间尺度上，降水与宏观 地形 因素有良好的相关性；

Conclusions The corneal diopter measured by the topographer was more accurate than that measured by the keratometer especially for the patients cornea was too steep flat or corneal opacity .

结论角膜 地形 图 仪 系统测量角膜屈光度更为准确、全面，尤其对角膜过陡、过平、有 斑翳、云翳者的检测 结果 更有 参考价值。

Methods : Six kinds of chromium-cobalt pieces with different surface were determined by Talysurf / S5-CD topographer .

方法：用 Talysurf/S5-CD型表面形貌 仪测定六组软质钴铬合金试片表面粗糙度。
