目的 探讨FS200飞秒激光制作不同厚度角膜瓣的安全性.方法 采用前瞻性随机临床对照研究.选取2013年6月至2013年12月在泉州180医院眼科行飞秒全激光屈光手术的患者按就诊顺序随机分为四组,每组100只眼,分别采用FS200飞秒激光制作四种厚度(90、100、110、120 μm)的角膜瓣,比较四组术中及术后并发症发生率.结果 四组术前年龄(x2=5.419,P=0.144)、性别(x2=0.362,P=0.948)、角膜曲率(x2=5.865,P=0.118)、角膜厚度(x2=4.783,P=0.188)和患者因素评分(x2=0.007,P =1.000)比较差异无统计学意义(P＞0.05);四组术中及术后并发症发生率比较差异无统计学意义(x2=14.539,P=0.975).结论 术者熟练掌握手术技巧,术中操作认真仔细,设置隧道细致精确,患者配合良好,无小睑裂深眼窝等情况下,FS200飞秒激光制作薄至90 μm不同厚度角膜瓣的安全性是一致的.但瓣不是越薄越好,要权衡利弊,综合考虑,合理选择,不应盲目追求薄的角膜瓣.

Objective To discuss the safety among individual corneal flaps of different thickness created by FS200 femtosecond laser.Methods In a prospective randomized sample controlled clinical study.Patients made all-in-laser refractive surgery in the 180 Hospital of Quanzhou from June 2013 to December 2013 were randomly divided into four groups according to the order of treatment.Each group of one hundred eyes created corneal flaps of four thickness (90,100,110,120μm) by FS200 femtosecond laser.Compared the incidence of intra-and post-operative complications among four groups.Results No statistical differences of age (x2=5.419,P =0.144),sex (x2=0.362,P =0.948),corneal curvature (x2=5.865,P =0.118),corneal thickness (X2=4.783,P =0.188) and patient factors' score (x2=0.007,P =1.000) were found before operation among four groups.There were no difference in the incidence of intra-and post-operative complications among four groups (x2=14.539,P =0.975).Conclusions If the surgeon operates familiarly,the assistant sets up the canal precisely and the patients cooperate well without mild blepharophimosis or deep eye socket,the safety of creating individual corneal flaps of different thickness thinnest to 90μm by FS200 femtosecond laser is uniform.But corneal flap is not the more the better thin.We should weigh the advantages and disadvantages and consider comprehensively to choose reasonably.The blind pursuit of thin flap is unreasonable.
