And a satisfactory effect of fisheye image distortion correction is ultimately achieved by applying spherical coordinate orientation approach based on scans line approach.

在此基础上，采用球面坐标定位校正方法进行图像扭曲变形校正，取得了较好的图像校正效果。

Based on the principle of the correction for spherical myopia using small beam laser, our excimer laser corneal surgery system has been able to performs uch refractive surgery.

基于这种激光修正角膜矫正近视的原理，我们研制的准分子激光眼科治疗仪实现了治疗近视。

Methods: 3 eyes of 2 patients with eccentric ablation and spherical refraction were received correction, with the topography guided LASIK according to the design.

方法：角膜地形图引导准分子激光矫治2例3眼切削偏心，同时，矫正欠矫的球镜度数。
