LASIK术后9年外伤致角膜瓣撕裂1例

One Case Which Injury Lead to Corneal Flap Laceration after LASIK Nine Years Ago

摘要: LASIK术后外伤致角膜瓣移位、皱褶时有报道，及时复位角膜瓣是公认的处理原则，但是在复位术中如果处理不当可于术后出现上皮植入、上皮内生、角膜瓣融解、角膜感染、层间弥漫性角膜炎(DLK)等并发症。特别是板层刀作瓣的LASIK手术，与飞秒制瓣相比在外伤状况下更容易发生角膜瓣移位甚至撕裂。本文回顾了1例9年前曾行角膜板层刀制瓣的LASIK手术患者的临床资料，其在1个月前被抓伤致角膜瓣撕裂，伤后一天于我院行角膜瓣复位，术后恢复良好。但是该病例也提醒我们，角膜瓣层间的愈合非常微弱，向患者宣教LASIK术后的注意事项十分必要。

Abstract: Corneal flap dislodged and folds after LASIK have been reported repeatedly. Resting corneal flap is accepted principles of acute. However, improper handling operation may show up epithelial in-growth, corneal flap melting, corneal infection, DLK and other complication. Especially, LASIK using moria microkeratome will more easily show corneal flap dislodged, even laceration. This paper retrospect the clinical data of surgical patients who received operation of LASIK happened 9 years ago. Last month, the patient has been scratched and led to corneal flap laceration. One day after that, the patient do corneal flap resting operation in our hospital, and recover very well. But this case also reminds us that the layer between corneal flap is very weak. So it is very important to tell the patient notes after LASIK.
