目的比较兔眼LASIK与LASEK两种准分子激光手术后角膜神经损伤和再生修复情况.方法选用健康、纯种新西兰白兔30只,随机分为6组,每组5只,1组为正常对照组,其余5组为实验组,实验组白兔一眼行LASIK手术;另一眼行LASEK手术.术后1、7 d,1、3、6m取兔角膜行氯化金染色,光镜下观察LASIK与LASEK术后角膜神经损伤及修复情况.结果 LASIK与LASEK手术后不同时期角膜神经损伤和再生修复有明显差异.结论 LASIK术后角膜神经损伤的程度比LASEK重,角膜神经再生修复速度慢.

Objective To investigate the comparison with corneal nerve injury and recovery of rabbits after LASIK and LASEK. Methods Selected thirty healthy, peal-bred New Zealand white rabbits, then divided into 6 groups randomly, 5 rabbits each group, 1 was normal control group, the remaining 5 groups as the experimental group. One eye underwent LASIK and LASEK on the contrast eye in the experimental group. The rabbits were killed at 1 day, 7 days, 1 month, 3 and 6months after surgery. Corneal nerves were stained with the gold chloride staining method. The changes in corneal nerve injury and recovery were observed after LASIK and LASEK with microscope. Results There were obvious differences in corneal nerve injury and recovery in different periods after LASIK and LASEK. Conelusions Corneal nerves are injured more severely and recover slower after LASIK than LASEK.
