The difference of mean intraocular pressure among readings obtained with the lens in place, after lens removal and lens reinsertion were not statistically significant in bandage contact lens group and in low myopic contact lens group. But the high myopic contact lens group showed statistically significant difference of mean intraocular pressure obtained with the lens in place, after lens removal and lens reinsertion. In addition, the intraocular pressure readings measured immediately after myopic contact lens reinsertion revealed poor reliability.关键词 Tono-Pen , Soft contact lenses

我们把受测者分为三组：低度近视组，高度近视组和配戴治疗性隐形眼镜组，每组分别以受测者未戴隐形眼镜时的眼压做基准，而以其他三种情形的眼压分别与之比较，结果发现以Tono-Pen测量低度近视组和配戴治疗性隐形眼镜组的眼压值可信度较高，但是戴上隐形眼镜之后马上测量的眼压值较不准确，而高度近视组的测量值则出现变异的现象，可信度较低。

It is difficult to be simulated and analyzed due to the excessive surfaces, complex structure and locomotory parts in zoom lens. All the transmission planes taken as the partial reflection and partial transmission planes were simulated with ASAP（advanced system analysis program）and the stray rays on "dangerous surfaces" which easily generate the ghost images in zoom lens were analyzed. Based on it, the zoom lens was optimized and the quality of image was improved by changing the curvature and refractive index of the second reflection planes.

利用ASAP软件模拟每个透射面作为部分透射、部分反射的表面，对变焦光学系统非轴上光进行分析，模拟出变焦系统的光学元件表面和光机内壁，实行实际光线追迹，然后以像面为研究对象，进一步实施实际光线追迹，模拟出全部散射光在像面上的能量分布，找出鬼像形成的原因，并在此基础上通过改变二次反射所在面的曲率或改变所在面的折射率两种方法对变焦光学系统进行优化，减小鬼点数目，以提高系统的成像质量。
