目的　探讨 L ASIK后角膜异物的临床特点 ,寻找较好的处理方法 ,避免产生严重并发症。方法　对 34例 L ASIK后角膜异物 ,根据异物的大小、化学性质、嵌入角膜的深浅、所引起角膜与前房的反应情况及 L ASIK后时间的长短 ,给予不同处理。结果　所有病例均无角膜瓣移位及皱折 ,除外角膜瞳孔区留有瘢痕者 ,其余均对矫正视力无影响。结论L ASIK后早期 ,患者对角膜异物感觉不明显 ,自觉症状较正常情况轻 ,一旦异物损伤角膜较深 ,角膜反应重并波及前房发生炎症反应。但只要及时正确处理 ,一般预后较好 Objective To investigate the clinical features of corneal foreign bodies after LASIK and to find a better treatment method to avoid serious complications. Methods Thirty-four cases of corneal LASIK corneal foreign bodies were treated with different treatments according to the size, chemical properties, depth of cornea embedded, corneal reaction with the anterior chamber and the length of time after LASIK. Results No cases of corneal flap displacement and crease in all cases, except for those with scarring in corneal pupil area, the rest had no effect on corrected visual acuity. Conclusion In the early stage after LASIK, the patients had no obvious sensation to corneal foreign bodies and the symptoms were less than normal. Once cornea was damaged by foreign body, the corneal reaction was heavy and inflamed the anterior chamber. But as long as the proper treatment in time, the general prognosis is good
