作者于1962年根据加利略望远镜放大原理,于前房内植入一凹透镜,使眼的屈光力等于-30屈光度,在角膜前13毫米处再放+20屈光度的透镜,可使物象放大1.75倍。但由于凸透镜的物镜,视野将缩小约35度,故此镜最好用于双眼黄斑部有病变,而周 The author in 1962 according to Galileo telescope principle of amplification, implanted in the anterior chamber of a concave lens, the refractive power of the eye is equal to -30 diopters, 13 mm in front of the corpus and then put +20 diopter lens, the image can be magnified 1.75 times . However, due to the convex lens objective lens, field of vision will be reduced by about 35 degrees, so the mirror is best used for macular lesions in both eyes, and weeks
