目的:对比分析飞秒激光和角膜板层刀行准分子激光原位角膜磨镶术(laser
in situ keratomileusis,LASIK)术后患者的视觉质量及角膜瓣变化。
方法:选取2009-03/2012-03将接受飞秒激光35例70眼患者和接受角膜板层刀的患者45例90眼进行对比研究,两组术后视觉质量和角膜瓣进行对比。
结果:视觉质量比较:两组患者所行的手术均有显著的可预测性、有效性及安全性,且术后像差和对比敏感度及视力差异不显著,组间差异无统计学意义(P>0.05); 角膜瓣比较:两组患者在水平方向的角膜瓣厚度组间差异无统计学意义(P>0.05)。
结论:飞秒激光和角膜板层刀行LASIK术后具有良好的视觉效果,且角膜瓣厚度差异不显著,值得临床推广使用。

[Abstract]
AIM: To compare changes in visual quality and the corneal flap after LASIK surgery with femtosecond laser and microkeratome.
METHODS: The study enrolled 80 patients who received LASIK surgery from March 2009 to March 2012 in our hospital. Among them, femtosecond laser was used for 35 patients and microkeratome was used in the other 40 patients, The two groups were compared with each other in postoperative visual quality and the corneal flap.
RESULTS: Visual quality: the two surgical procedures both had significant predictability, efficacy and safety, and there was no significant difference between the two groups in postoperative visual aberrations and contrast sensitivity(P>0.05); Corneal flap: There was no significant difference between the two groups in corneal thickness at the same horizontal points(P>0.05).
CONCLUSION: LASIK surgeries with femtosecond laser and microkeratome, both produce good outcome of vision and the difference in the postoperative corneal flap thickness between the two techniques is not significantly different.
