目的:探讨LASEK术中使用乙醇软化角膜上皮的理想时间和影响上皮瓣制作的原因.方法:总结2007-01/2008-03在我院行LASEK的581例(1 146眼)使用200mL/L乙醇采取不同时间软化角膜制作上皮瓣,其中15s者67眼,18s者230眼,20s者271眼,22s者70眼,25s者235眼,28s者273眼.术前配戴角膜接触镜0.5a以上者424眼(37.00%).结果:上皮瓣制作成功1 019眼(88.92%),各时间组的成功率分别是:15s者58.21%,18s者85.65%,20s者87.82%,22s者91.43%,25s者94.47%,28s者94.87%.术前配戴角膜接触镜的424眼的成功率分别是15s者33.33%,18s者71.43%,20s者75.00%,22s者87.50%,25s者87.21%,28s者88.10%.无角膜接触镜配戴史722眼的成功率分别是:15s者72.09%,18s者96.21%,20s者95.32%,22s者94.74%,25s者98.66%,28s者97.88%.结论:LASEK术中采用200mL/L乙醇浸泡角膜的合理时间在术前无角膜接触镜配戴史的是18s,配戴角膜接触镜0.5a以上的应延长到25s,长期配戴角膜接触镜是影响上皮瓣制作的主要原因.
