准分子激光屈光矫正系统及实验研究

Development and experimental study of excimer laser refractive system

摘要: 以飞点扫描切削模式为基础,研制小光斑飞点扫描准分子激光角膜屈光矫正系统。利用此扫描系统做了PMMA板和角膜对比实验以及动物和盲眼实验。实验结果表明,该矫正系统具有治疗时间短、矫正精度高、角膜切削表面光滑,易于集成波前像差技术实现“个体化切削”方案等优点,具有较好的临床应用前景。

Abstract: The small scanning-spot excimer laser corneal system was developed based on flying-spot scanning model.The comparative experiment between PMMA and cornea was fulfilled as well as clinical animal and blind eyes experiments.The experimental results show that the excimer laser refractive system is characteristic of short cure time,high accuracy,surface smoothness and easy to integrate the wavefront aberration technology.
