目的探讨准分子激光原位角膜磨镶术(LASIK)后角膜层间异物情况。方法在行LASIK手术的2135例(4223眼)中,对术后出现角膜层间异物残留病例的相关原因和处理方法进行临床分析。所有手术均实施规范化操作,术毕以裂隙灯显微镜检查,如发现角膜瓣下异物,即刻以掀瓣冲洗或手法去除等方法,力争手术当日处理完毕。术后按常规时间复诊观察角膜情况,术后次日以后尽可能不予掀瓣处理异物。结果 102眼(1.92%)出现角膜层间异物残留。其中,21眼(0.50%)采用异物剔除和冲洗等及时合理的措施处理;81眼(1.92%)无需处理。所有病例预期的矫正视力均无明显影响。结论 LASIK术后出现角膜层间异物残留并发症的比例较低,多数病例无需处理。及时合理的处理方法能提高视觉质量,LASIK手术安全可靠。从业人员技术、环境设备等多方面加强预防,可明显降低术中异物的发生率。
Objective To investigate the corneal foreign body after excimer laser in situ keratomileusis (LASIK). Methods In 2135 cases (4223 eyes) undergoing LASIK surgery, the causes and treatment of postoperative residual corneal interlaminar foreign body were analyzed. All operations were implemented standardized operation, surgery completed by slit lamp microscopy, such as the discovery of corneal flap foreign body, immediately flap lift or removal methods, and strive to deal with the day of surgery. Follow-up routine postoperative observation of corneal situation, after surgery the next day as far as possible not to lift the flap to handle foreign body. Results 102 eyes (1.92%) had corneal intercostal foreign body residue. Among them, 21 eyes (0.50%) were treated with timely and reasonable measures such as rejection and flushing of foreign bodies; 81 eyes (1.92%) did not need treatment. Corrected vision in all cases had no significant effect. Conclusion The residual corneal foreign body residual complications after LASIK are low, and most cases do not need to be treated. Timely and reasonable treatment can improve visual quality, LASIK surgery safe and reliable. Practitioners, technology, environmental equipment and many other aspects of prevention, can significantly reduce the incidence of intraoperative foreign body.
