柱面散光轴位角进行手动测量，数码显示的数字化屈光度测量仪。本仪器采用特殊的处理电路，消除了外来噪声产生的误触发脉冲及输出错误积累而引起的位置偏移。

This instrument has a rotary encoding and raster and it has a special processing circuit not only eliminating trigger pulse case by noise but also clearing up position accumulates error.

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。

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.

报道对无明显眼病，屈光度在- 6.00 D以上的高度近视患者155例(287眼)，分别行角膜厚度、角膜前面曲率半径测量及角膜内皮细胞计数。

The results of corneal thickness, radius of curvature and endothelium in 155 patients 287 eyes who had high myopia with over -6.00d and no distinct ocular disorders are reported.
