Visx20/20B准分子激光治疗系统激光腔状态与治疗效果的关系分析

目的 分析Visx20/20B准分子激光系统激光腔状态与治疗效果的关系，探讨最佳激光腔状态，同时提出改进激光腔状态的方法，以获取手术最佳疗效。方法观察手术过程中激光腔的各种状态和术后病人的治疗效果，将激光腔各种状态与病人疗效进行对比，做出定性分析。在以后的工作中，随时根据激光腔状态来调整我们的治疗方案，从而力争达到病人的最佳治疗效果。结果 激光腔状态包括气体、激光腔本身清洁度、CV值、前后镜等几部分，对病人疗效影响较大。结论 准分子激光手术中，Visx20/20B型准分子激光系统激光腔各部分的状态与手术疗效有很大关系，必须随时关注激光腔状态，以保证手术最佳疗效。

Analysing the relation between the state of the Laser cavity and the treating effect of Visx20/20B Excimer Laser system

0bjective Analysing the relation between the state of the Laser cavity and the treating effect of Visx20/20B Excimer Laser system. Discussing the best state of the Laser cavity. Bring forward the methods of improving on the state of the Laser cavity so that, obtain the best treating effect. Methods Observing all kinds of the state of the Laser cavity in course of operation and the treating effect of the patient after operation. Comparing all kinds of the state of the Laser cavity and the treating effect of the patient so that make out qualitative analysis. Then adjusting the plan of cure according the stale of the Laser cavity for obtain the best treating effect.Result The state of the Laser cavity that include the state of gas,sanitary degree of the Laser cavity, CV value,the anterior and posterior mirror, etc.They influence the treating effect greatly. Conclusion In course of Excimer Laser Operation, the state of every part of the Laser cavity of Visx20/20B Excimer Laser system are connected with the treating effect of the operation. We must pay attention to the state of the Laser cavity, and correct it at any moment for the best treating effect.
