原位角膜磨镶术后迟发性弥漫性板层角膜炎

目的：报告1例LASIK术后11mo由于角膜损伤引起的弥漫性板层角膜炎（diffuse lamellar keratitis，DLK）。方法：22岁女患者应用laser Sight SLX准分子激光机和MoriaII角膜板层刀行双眼原位角膜磨镶术（1aser in situ keratomileusis，LASIK），术中和术后早期未见并发症发生。结果：LASIK术后11mo，由于书页损伤角膜上皮，右眼诊断为I级DLK。经局部应用皮质类固醇激素，2wk后DLK很快治愈，没有并发症发生。结论：DLK经常发生于术后早期，但也可发生于术后数月，一旦确诊应迅速治疗，效果良好。

Delayed onset diffuse lamellar keratitis following laser in situ keratomileusis

AIM: To report a case of late onset diffuse lamellar keratitis (DLK) after laser in situ keratomileusis(LASIK) in 11 months due to corneal trauma. ·METHODS: A 22-year-old female patient underwent uneventful bilateral LASIK using a laserSight SLX excimer laser and Moria II microkeratome. No complications were observed during the operation and the early postoperative period.·RESULTS: 11 months after LASIK, grade I DLK was diagnosed after the book paper hurt the right corneal epithelium. The DLK responded rapidly to topical corticosteroid therapy, and healed in 2 weeks without complication. ·CONCLUSION: Although DLK Wpically develops in the early postoperative period, it could occur months after surgery. Treatment should begin as soon as DLK is diagnosed.
