Result The epithelium was thinner 54.3±8.44μm in the contact lens group than for the control group, and the density of basal epithelium was cells was lower too(3705.00±447.62/mm^2), and an increased number of microdot opacities in the contact lens group compared to the control group as apparent (P.05), more Langhans cells in the contact lens group is dendriform.

结果 1。佩戴角膜软性接触镜组与对照组相比，基底上皮细胞密度减少，为3705.00±447.62个／平方公厘(P.05)，角膜上皮层厚度变薄，为54.3±8.44μm(P.05)，并有部分剥脱。2。

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。
