摘　　要：目的评估Ziemer LDV Z6飞秒激光机制作角膜瓣的FS-LASIK手术的并发症处理及长期治疗效果。方法回顾性临床研究。对我院2016年1月至6月采用Ziemer LDV Z6飞秒激光机制作角膜瓣的FS-LASIK手术治疗近视并有至少3年的术后随访资料患者的临床数据进行分析。统计角膜瓣相关各种并发症的发生率,并比较术前及术后6个月、1 a、3 a的视力、等效球镜度等。结果本研究共纳入1741例(3158眼)患者,其中49眼发生并发症,并发症总体发生率为1.55%,与角膜瓣相关的并发症41眼,占总体并发症的83.67%,占总手术眼数的1.30%。术中和术后均未见严重影响术后视力的并发症发生。术后不同时间裸眼远视力和等效球镜度均较术前有明显改善(均为P=0.00);术后不同时间点间的裸眼远视力差异无统计学意义(P>0.05);术后3年等效球镜度较术后6个月有一定回退(P=0.00),但仍保持在轻度过矫远视状态。结论Ziemer LDV Z6飞秒激光机制作角膜瓣的FS-LASIK手术并发症均比较轻微;患眼在术后3年内能够保持良好和稳定的裸眼远视力。Objective To evaluate the incidence and management of complications of laser in situ keratomileusis(LASIK)using Ziemer LDV Z6 femtosecond laser,and to evaluate the long-term therapeutic effect of this surgery.Methods Retrospective clinical study.The clinical data of patients who underwent LASIK using Ziemer LDV Z6 femtosecond laser for treating their myopia with 3 years follow-up from January 2016 to June 2016 were analyzed.The incidence of corneal-flap-related complications was calculated.The differences in visual acuity and diopter were compared before and 6 months,1 year,3 years after operation.Results Totally,1741 patients(3158 eyes)were included in this study.The overall incidence of complications was 1.55%(49 eyes).Complications related to corneal flap accounted for 83.67%(41 eyes)of the total complications and 1.30%of the total number of eyes.There were no intra-and postoperative complications seriously affecting postoperative vision.The uncorrected distance visual acuity and diopter in postoperative period were significantly improved compared with their preoperative data(all P=0.00);there was no difference in uncorrected distance visual acuity at different time points postoperatively(P>0.05).There was a regression in diopter 3 years after operation(P=0.00),but mild hyperopia remained at the end of 3-year follow-up.Conclusion The complications of LASIK using Ziemer LDV Z6 femtosecond laser were mild.The patient can get good and stable uncorrected distance visual acuity for 3 years postoperatively.Ziemer LDV Z6 has a good effect on creating corneal flap for LASIK.
