目的:通过对620例合并感染的角膜铁质异物在裂隙灯下取出的临床分析总结治疗操作技巧,减少严重并发症的发生。方法:对620例合并感染的角膜铁质异物在局部麻醉后裂隙灯下用异物针取出。结果:通过上述方法将合并感染角膜异物取出无铁锈残留,无角膜穿孔及色素膜炎继发青光眼、眼球萎缩等并发症的发生。结论:在裂隙灯显微镜下取出,合并感染的角膜异物,视野清晰,操作方便,易观察到异物位置、深浅铁质氧化感染范围及前房色素膜反应,具有准确取出及时控制感染抢救视力等优点,便于在基层医院推广应用。

AIM:To reduce severe complications occurrance by analysis the infection cornea with iron foreign in 620 cases. METHODS:Totally 620 cases of infective cornea with iron foreign underwent topical anesthesia and the foreign body was removed with needle. RESULTS:The infective corneas by the above method had no residual of corneal foreign bodies,and no uveitis, corneal perforation,secondary glaucoma or ocular atrophy occurred. CONCLUSION:The infective cornea with foreign body needle under slit-lamp have a clear vision,accurate, infection,easy to operate and suit to primary hospitals; This method also can observe the location,scope of foreign body and depth of anterior chamber infection,and oxide pigment membrane reaction.
