LASIK术中角膜刀与角膜瓣厚度关系的临床研究

目的：通过对角膜瓣厚度的临床观察，找出角膜刀与角膜瓣厚度的相关因素，从而确保手术的安全性。方法：对在我院行LASIK治疗的患者进行术后追踪观察3～6个月，分为90刀组和110刀组，通过统计学处理找出90刀及110刀制作角膜瓣的厚度值。结果：90刀组的角膜瓣厚度值为（116．55±12．36）μm，110刀为（138．37±12．48）μm。结论：LASIK术中角膜瓣的厚度在理论上是固定的，但在临床实践中发现角膜瓣的厚度与理论值存在较大偏差，故提醒我们设计角膜切削深度时一定要结合本单位设备情况及术者的经验找出自己的角膜瓣厚度值．从而确保手术的安全性。

Clinical Study of the Correlation between Microkeratome and Corneal Flap Thickness in LASIK Surgery

Objective:By clinical observation of corneal flap thickness,find out the relevant factors of the correlation between microkeratome and corneal flap thickness,so as to ensure the safety of surgery.Method: Patients in my hospital for LASIK treatment with follow-up after 3 to 6 months,the knife is divided into 90 groups and 110 groups through statistical analysis to find out the value of the thickness of the corneal flap that 90 and 110 knife make.Results: Corneal flap thickness value of the group of 90 knife ...
