摘　　要：目的分析高度近视LASIK治疗中,影响角膜瓣厚度的因素。方法40例(80只眼)屈光度为-7.00D^-9.00D的高度近视患者,运用MoriaM2板层刀制作角膜瓣,对角膜曲率不同、板层刀负压吸引力不同、M2刀片新旧不同进行分组,对术前、术后屈光度、视力及剩余角膜基质床厚度进行分析比较。结果Ⅰ组板层刀负压吸引力相同时角膜曲率不同,制作出的角膜厚度不同,两者有明显差异(P<0.05);Ⅱ组角膜曲率相同,板层刀负压吸引力不同,制作出的角膜瓣厚度不同,两者有明显差异(P<0.05);Ⅲ组板层刀片新旧不同,制作出角膜瓣的厚度不同,两者有明显差异(P<0.05);结论LASIK治疗高度近视时,对一个有经验的手术医生制作一个80~110μm的薄角膜瓣是合理的,能有效防止术后屈光回退和医源性圆锥角膜的发生。Objective To evaluate the intraqoperative thickness in laser situ keratomileusis for high myopia. Methods 80 eyes of 40 cases with high myopia （ - 7.00D ～ - 9.00D） who received lasik, it made the corneal flap using Moria M 2. They were divided 3 groups for different corneal curvature, different of Mofia carriago-Barraguerm icrokeratome, different knife with new or old, The pre-LASIK and post-lasik refactive diopter, visual acuity and residual stromol thickness were compared. Results The knife head was the same, the corneal thickness was different, the corneal flap thickness was different. There were obvious difference in group I （ P 〈0.05）. The corneal curvature was the same the was different, the corneal flap thickness was different, there were obvious difference in group Ⅱ （ P 〈 0.05 ）. The knife was different, the was different, there were obvious difference in group Ⅲ （ P 〈 0.05 ）. Conclusion It is reasonable that the corneal flap thickness was 90 - 110μm in lasik for high myopia. It makes residual stromal thick to prevent regression and keratoconus.
