准分子激光角膜屈光成形术(PRK)是近年发展的新技术,VISX20/20准分子激光器是由 Charles Munnerlyn博士设计,为 VISX 公司制造的产品。美国 ALCON 公司与其结成商业伙伴并负责它在全球范围的销售。现有近200台 VISX20/20准分子激光机分布在世界30余个国家和地区,治疗近视、散光及远视患者逾十余万,有效率100%。该机特点:(1)总输出能量500mJ,激光储备能量高、寿命长。(2)近视治疗光学区6mm,无术后眩光。(3)激光束能量分布均匀,角膜基质切削表面平滑,可加速术后上皮再生,减少术后远视改变。(4)光滑切削模板可供镜度计检查,并分析激光器工作状况。(5)碎屑回收系统保证角膜基质切削表面的平滑,避免医源性散光。(6)超低温气
Excimer laser keratomileusis (PRK) is a new technology developed in recent years, VISX20 / 20 excimer laser designed by Dr. Charles Munnerlyn, VISX company’s products. American ALCON company and its business partners and responsible for its worldwide sales. Nearly 200 existing VISX20 / 20 excimer laser machines are located in more than 30 countries and regions in the world. The treatment of myopia, astigmatism and hyperopia in patients with more than ten million, the efficiency of 100%. The machine features: (1) the total output energy 500mJ, high energy laser storage, long life. (2) myopia treatment optical zone 6mm, no postoperative glare. (3) uniform energy distribution of the laser beam, corneal stripping surface smooth, can accelerate postoperative epithelial regeneration, reduce postoperative hyperopia changes. (4) smooth cutting template for mirror inspection, and analyze the working conditions of the laser. (5) debris recovery system to ensure that the corneal stromal cutting surface smooth, to avoid iatrogenic astigmatism. (6) ultra-low temperature
