目前世界是有8亿人患近视,苏联专家研究出矫正这种疾患的新方法,即辐向角膜切割术。采用这种方法可使90％的患者恢复视力,其余人的视力也将大大改善。苏联专家认为,这种手术实际上是胶原分子手术,是借助于器械来再生分子结构,这种器械已由苏联研制成功,称之为超薄钻石刀。角膜基质胶元纤维的厚度是在190～1000(?),采用金属刀片时切缝宽度大 There are 800 million people in the world now suffering from myopia. Soviet experts have developed a new method to correct this condition, namely radial keratoplasty. Using this method will enable 90% of patients to restore vision, the rest of the people’s vision will also be greatly improved. Soviet experts believe that this surgery is actually a collagen molecular surgery, is the use of equipment to reproduce the molecular structure, this device has been successfully developed by the Soviet Union, called the thin diamond knife. Corneal collagen glue fiber thickness is 190 ~ 1000 (?), When using a metal blade kerf wide width
