摘　　要：目的探讨机械法准分子激光角膜上皮瓣下磨镶术(epi-LASIK)中上皮异常发生的原因及处理方法。方法回顾性分析70例139眼epi-LASIK手术操作记录。结果上皮异常共有10种,其中7种能通过术中适当应用技巧处理,使术毕时仍保持上皮完整。除瓣延展外,上皮完整22眼,发生率为15.8%;上皮缺失13眼,发生率为9.3%,二者发生率差异无统计学意义。结论Epi-LASIK术中出现上皮异常大部分可通过熟练技术避免,适当处理对手术效果影响甚微。Objective To investigate the t）pes and treatment of the epithelial flap complications during epipolie laser assisted in-situ keratomileusis procedure （LASIK）. Methods The incidence of epithelial flap complications was studied based on the surgical records of 139 LASIK operations and the reasons and treatment regimens were elucidated. Results There are 10 types nf abnormal epithelial flaps, uf which 7 couht well be treated by appropriate surgieal techniques and kept the flap complete. Except for flap ductility （ 100% incidence）, the incidence of abnormal flaps was 15.8% （22/139）, epithelial absence, including small epithelial flap, irregular epithelial flap and free epithelial flap, was 9.3% （13/19）. There was no si~,mificant differ- enee in the rate of enmplieations between epithelial existence and epithelial absence . Conclusion Abnormal epithelial flap is commonly seen in epipolic -LASIK, but it can be prevented by skilled technique and no signifieant adverse effect on the outcome.
