To describe the indications and technique for repositioning the laser in situ keratomileusis (LASIK) flap at the slit lamp.
We present a description of patients with striae or slippage of the flap who had repositioning of the flap at the slit lamp.
Indications for repositioning at the slit lamp are mostly flap striae. However, it can also be done for a displaced flap and small amounts of debridement. This procedure is not recommended for taking cultures, irrigation of diffuse lamellar keratitis, suturing the flap, or epithelial ingrowth. Repositioning the flap is done by finding the edge of the flap with the cannula, lifting the flap, sweeping the cannula to release the entire wound, and infusing balanced salt solution under the entire flap. We did not encounter infection or recurrent epithelial erosion in these patients.
Repositioning the LASIK flap at the slit lamp was effective and safe in the treatment of striae or flap slippage. It saved time, money, and, anxiety for the patient.
描述在裂隙灯下重新定位准分子原位角膜磨镶术（LASIK）角膜瓣的适应证及技术。
我们介绍了在裂隙灯下对出现角膜瓣条纹或移位的患者进行角膜瓣重新定位的情况。
在裂隙灯下重新定位的适应证主要是角膜瓣条纹。不过，对于移位的角膜瓣和少量清创也可进行此操作。不建议将此操作用于采集培养物、冲洗弥漫性层间角膜炎、缝合角膜瓣或上皮内生的情况。通过用套管找到角膜瓣边缘、掀起角膜瓣、用套管扫过以松开整个伤口并在整个角膜瓣下注入平衡盐溶液来重新定位角膜瓣。在这些患者中我们未遇到感染或复发性上皮糜烂的情况。
在裂隙灯下重新定位LASIK角膜瓣在治疗角膜瓣条纹或移位方面有效且安全。它为患者节省了时间、金钱和焦虑。
