Objective:Since some limitaions of SRK Ⅱ formula,the dual cubic curved regressive formula was designed. methods:By means of computer,statistical analysis and regressive treatment of kerato diopter,axial length and emmetropic IOL diopter of 415 pseudophakia was done.

针对目前临床上常用的SRKⅡ公式在计算人工晶体屈光度时的局限性，对415只后房型人工晶体眼的角膜屈光力、眼轴长度和正视化人工晶体屈光度进行回归分析后，设计出一种不同于传统的线性回归公式的曲线回归公式——二元三次计算公式。

Objective To investigate the difference in amplitude of accommodation between emmetropic and myopic subjects with three methods of push-up test, minus-lens test and infrared optometer.

目的 分析正视和近视儿童用不同测量方法测量的眼调节幅度的差异(amplitude of accommodation， AMP)并初步探讨不同方法测量对眼AMP测量的影响。

Objective: To study the higher order aberrations of emmetropic and ametropic eyes with wavefront aberrometer.

目的：借助波阵面像差仪研究正视眼及屈光不正眼的高阶像差。

Methods: Forty of cases 77 emmetropic and ametropic eyes were measured with an aberrometer based on Tscherning's principle with the pupils dilated. The Zernike coefficients and root mean square values of wavefront aberrations up to the 6th order were recorded and statistically analyzed.

40人77只正视眼及屈光不正眼，散瞳后用基于Tscherning原理的波阵面像差仪进行测量，记录高达6阶的波阵面像差Zernike系数和均方根值，并进行统计学分析。

There was no significant difference of higher order wavefront aberrations between emmetropic and ametropic eyes. Comparing the age of 40 years or less with the age over 40 years, there were significant differences in RMS3 between the two under 7 mm pupil size, and statistical diffenences in RMS6 and RMSh between the two under 4 mm pupil size.

除第2阶像差均方根(RMS2)以外，正视眼及近视眼各阶像差平均RMS值在7 mm与4 mm瞳孔下，差异均无统计学意义。40岁及以下者与40岁以上者相比，在7 mm瞳孔时，两者第3阶像差均方根(RMS3)差异有统计学意义；而在4 mm瞳孔时，两者第6阶像差均方根(RMS6)及高阶像差均方根差异均有统计学意义。

Methods 129 healthy emmetropic subjects were divided into four groups according to their age.

将129例正视状态健康成人按年龄分为4组：A组为20~29岁，B组为30~39岁，C组为40~49岁，D组为50岁以上。

Objective To study the relationship between surgical prognosis of retinal detachment in emmetropic or myopic eyes and vitreous changes.

目的 研究正视眼视网膜脱离(retinal detachment，RD)患者的手术预后及其与玻璃体改变的关系。

It is possible that the vitreous characteristics in emmetropic eyes with RD have relationship to the occurrence and development of PVR that has the influence on the prognosis to some extent.

这种正视眼RD玻璃体的特殊病理过程，更易导致PVR的发生、发展，从而影响手术预后

Group 2 comprised 124 myopic, 206 emmetropic and 257 hypermetropic subjects.

近视，正视和远视的高血压患病率没有显著差异。

The surgical prognosis of RD especially by initial operation is worse in emmetropic group than that in myopic group. The lower occurrences of PVD and liquefaction but higher occurrence of focal vitreous concentration in emmetropic eyes may have impact on the prognosis.

正视眼RD患者的手术总治愈率及1次手术成功率明显低于近视眼RD患者，这与正视眼RD患者特有的PVD低发生率、玻璃体浓缩高发生率及较低的液化率有重要关系。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
