摘要
目的:探讨飞秒激光制瓣应用与准分子激光手术的临床效果。方法:选取准分子激光治疗中高度近视患者400例,随机分为两组,使其有可比性。其中对照组患者使用板层刀制作角膜瓣;观察组患者使用飞秒激光制作角膜瓣。对两组患者术后裸眼视力以及角膜瓣实测厚度进行比较。结果:术后1d、7d、1月、3月观察组患者裸眼视力较术前提高者分别占总数的41.50%、64.75%、68.25%和73.25%,均明显高于对照组;观察组患者术后实测角膜瓣厚度与设置值相比平均偏离15.46um,角膜瓣平均厚度与角膜顶点处角膜瓣厚度相差0.06um,而对照组上述两值分别为36.68um和16.54um。两组比较差异明显,有统计学意义(P<0.05)。结论:飞秒激光制作角膜瓣应用于准分子激光手术与传统板层刀相比具有更好的稳定性和安全性,是一种值得在临床中进行推广的手术技术。
Objective： To observe the clinical effects of application of femtosecond laser for valve and excimer laser operation.Method： 400 cases with high myopia treated with excimer laser operation were divided into 2 comparable groups,the control group and the observation group.The control group applied lamellar knife to make corneal flap,and the observation group used femtosecond laser to make corneal flap.Comparing the uncorrected visual acuity and corneal flap thickness measurement of the patients in 2 groups after operation.Result： A preoperative increase respectively of the patients in the observation group 1 day,7 days,1 month and 3 months after operation accounted for 41.50%,64.75%,68.25% and 73.25%,which was higher evidently than the control group.Measurement of corneal flap thickness and the set value of observation groups deviated 14.56um averagely,and the difference between corneal flap thickness and the average corneal vertex corneal flap thickness was 0.06um,but as for the control group,the 2 values above was 36.68um and 16.54um.The difference between the two groups was evident,which had statistical difference（P0.05）.Conclusion： Femtosecond laser making corneal flap applied in excimer laser operation has better stability and safety compared with traditional lamellar knife,and is a kind of operation technique which is worthy to be promoted.
