飞秒激光辅助LASIK治疗高度近视术后角膜后表面曲率变化的观察

摘要

目的：观察飞秒激光制瓣准分子激光原位角膜磨镶术（LASIK）矫正高度近视手术后角膜后表面曲率的变化。方法选择行飞秒激光制瓣LASIK矫正高度近视患者54例（102眼），分别在术前、术后1周、1月、3月、6月测量角膜后表面曲率。结果术后各时间点角膜后表面曲率同术前相比差异无统计学意义（P>0.05）。结论飞秒激光LASIK矫正高度近视术后角膜后表面曲率未发生明显变化，对于高度近视飞秒激光LASIK手术安全有效，但需要长期观察其安全性及有效性。%Objective To observe the change of posterior corneal curvature after LASIK with Femtosecond for high my-opia. Methods Chose 54 high myopia patients (102 eyes) for the correction by LASIK with Femtosecond. The posterior corneal curvature were measured before and after operation at 1 week, 1 month, 3 months , 6 months. Results There was no statistically significant difference in the changes of posterior corneal curvature between preoperation and postoperation. Con-clusion There is no significant change after LASIK with Femtosecond for high myopia. LASIK with Femtosecond is safe and effective for high myopia. But its safety and efficacy need long-term observation.
