我院自2006年元月开始 LASEK 手术,观察其对中、高度近视的矫治效果,现报告如下。资料与方法一、一般资料:共40例(80眼),年龄19～36岁;男性12例,女性28例。术前近视度数-6.00～-12.00,术前角膜厚度460～530um,术后随访6个月,采用 LASEK 的患者均为中、高度近视且角膜厚度偏薄,不适合 LASIK 的患者。二、手术方法:1.配制20%酒精。注意新鲜配置(1份酒精,4份无菌用水。注意不要使用塑料器皿及注射器),最好在术前10分钟以内配置,以减少挥发。2.用薄边环钻代替微型角膜刀标记手术区,然后在手术区域角膜表面用20%酒精浸泡大约30秒,使角膜边缘松解。3.再用角膜刮刀分离出一个厚度为60～80微米,直径8～10mm,带蒂的弧度为30°的上皮瓣(epitelial flap),掀开角膜
Our hospital from January 2006 LASEK surgery began to observe its effect on the treatment of high myopia, are as follows. Materials and Methods First, the general information: a total of 40 cases (80 eyes), aged 19 to 36 years; 12 males and 28 females. Preoperative myopia -6.00 ~ -12.00, preoperative corneal thickness 460 ~ 530um, postoperative follow-up 6 months, patients with LASEK are medium and high myopia and thin corneal thickness, is not suitable for patients with LASIK. Second, surgical methods: 1 preparation of 20% alcohol. Pay attention to the fresh configuration (1 alcohol, 4 sterile water, be careful not to use plastic containers and syringes), the best configuration within 10 minutes before surgery to reduce the volatility. 2. Replace the corneal knives with a thin-edged ring drill instead of the surgical area, and then soak the corneal surface with 20% alcohol in the surgical area for about 30 seconds. 3. Then use a corneal scraper to separate an epithelial flap (flap) with a thickness of 60 to 80 microns, a diameter of 8 to 10 mm, and a pedicle with an arc of 30 ° to open the cornea
