On account of four distortions such as signal lag, radial distortion, eccentric distortion and thin lens, etc. a precision distortion correction model is established.
新模型考虑了信号滞后、径向、偏心和薄透镜等四种畸变，建立了精确的畸变矫正模型。
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。
