【摘要】 目的 分析FEMTO LDV飞秒激光制瓣的LASIK(飞秒LASIK)手术并发症的发生原因,寻求相应对策。方法 回顾性系列病例研究。总结2009年12月至2013年10月在我院行FEMTO LDV飞秒LASIK手术治疗近视及近视散光的患者共1187例(2352眼),对其手术并发症进行临床分析。结果 术后3个月,UCVA达1.0以上者为94.64%,等效球镜度在±0.5 D内者为92.81%。共发生并发症35例(38眼,1.6%),术中并发症有角膜瓣偏心或超小瓣11眼(0.47%),角膜瓣形成不全2眼(0.08%),游离瓣1眼(0.04%),角膜瓣边缘切割不完全3眼(0.13%),角膜瓣边缘切割不规整3眼(0.13%),角膜瓣层间切割不完全而掀瓣困难2眼(0.08%),术中角膜上皮剥脱2眼(0.08%),气体垂直爆破3眼(0.13%),角膜缘气泡或层间气泡4眼(0.17%)。术后并发症有黄斑出血1眼(0.04%),病毒性角膜炎复发2眼(0.08%),角膜上皮下混浊4眼(0.17%)。以上并发症经过恰当的术中和(或)术后处理均获得满意的临床效果。结论 FEMTO LDV飞秒LASIK手术虽然具有较高的安全性、有效性和可预测性,但仍需防范并发症的发生。

【Abstract】 Objective To investigate the causes and the treatments of the complications from femtosecond laser flap creation for LASIK. Methods This clinical study of intraoperative and postoperative complications involved 2352 eyes of 1187 myopic and astigmatic patients who underwent FEMTO LDV femtosecond laser flap creation for LASIK between December 2009 and October 2013. Results Three months postoperatively, 94.64% of UCVA reached 1.0 or above and 92.81% of spherical equivalent refractions were ±0.5 D. Thirty-eight eyes of 35 patients developed complications, among them, 11 eyes had decentered or short flaps (0.47%), 2 eyes had button holes (0.08%), 1 eye had a loose flap (0.04%), 3 eyes had flaps with an incomplete margin (0.13%), 3 eyes had flaps with an irregular margin (0.13%), 2 eyes had an incomplete interlayer keratectomy (0.08%), 2 eyes had major epithelial sloughing (0.08%), 3 eyes had a vertical gas breakthrough (0.13%), 4 eyes had an opaque bubble layer (0.17%), 1 eye had a postoperative macular hemorrhage (0.04%), 2 eyes had viral keratitis (0.08%), and 4 eyes had subepithelial haze (0.17%). All patients had satisfactory clinical results with proper intraoperative and/or postoperative treatment. Conclusion Although FEMTO LDV femtosecond laser flap creation for LASIK is relatively safe, efficacious and predictable, the prevention of complications is still important.
