世界人口的1/4是近视患者,而我国更是近视眼高发区,据上海等地调查医科大学生毕业时近视眼患病率高达70％,且还有上升趋势,防治近视眼是有关民族健康的大问题。 判断一种治疗方法是否有效,可从其作用原理来考察分析,用手术改变角膜曲率(如角膜放射状切开,准分子激光光学角膜切除等)与戴眼镜(包括角膜接触镜)一样可矫正屈光不正,使所视物成像在视网膜上。此外,几乎无任何方法可改变真性近视。 配戴框架眼镜矫正屈光不正是科学、安全的方法,几百年沿用至今。但对于高度屈光参差患者,二侧物象相差悬殊,不能融合,导致无立体感,无双眼单视,并可 One-fourth of the world’s population is myopic patients, and myopia is the high incidence of myopia, according to Shanghai and other places survey of medical students graduate myopia prevalence rate as high as 70%, and there is an upward trend in the prevention and treatment of myopia is related to national health Big problem Determine whether a treatment method is valid, from the principle of its role to examine the analysis, surgery to change the corneal curvature (such as corneal radial incision, excimer laser optical corneal resection, etc.) and wear glasses (including contact lenses) can be corrected Light is not correct, so that the visual image of the retina. In addition, there is almost no way to change true myopia. Wear glasses to correct refractive errors is a scientific and safe method, which has been used for hundreds of years. However, patients with a high degree of anisometropia, the difference between the two sides of the image, can not be integrated, resulting in no stereoscopic, binocular vision, and
