Analysis of measuring corneal refractive power by corneal topographer compared with by keratometer

角膜地形图仪和角膜曲率计测量角膜屈光力的差异分析

Sex, refractive state, accommodative power, anterior chamber depth, vitreous chamber length and head circumference affected ocular axis length.

影响眼轴长的因素有性别、屈光状态、调节能力、前房深、玻璃体腔长和头围。

Results After surgery, refractive power on corneal anterior surface decreased significantly in peripheral zone at 1 week ( P < 0.01).

结果巩膜环扎外加压术引起角膜前表面周边部术后1周屈光度显著减小（P<0.01）；

平山病颈椎屈曲度异常的X线征象及其诊断价值角膜地形图仪和角膜曲率计测量角膜屈光力的差异分析

Similar to the case of cubic nonlinear refractive index, the loss will make the width of the power gain spectra of modulation instability become narrower and the peak gain smaller.

和只有三阶非线性的情况类似，损耗也会使不稳定增益谱的谱宽变窄，谱峰减小；

Efficacy measures include axial length, keratometric power and mean absolute refractive error.

有效测量值包括眼轴长度, 角膜曲率和绝对屈光误差值等内容.
