所述的马丁内兹展宽器由凹球面反射镜、平面反射镜和光栅组成；所述的压缩器由平面反射镜、内直角形反射镜和光栅组成，其特征在于，展宽器的光栅条纹密度大于压缩器的光栅条纹密度；展宽器中的凹球面反射镜曲率半径位0.9～1.2米，光栅距凹球面反射镜的位置为凹球面反射镜曲率半径的1/3～1/2。

The eyes were periodically examined by retinoscopy, and A-scan ultrasonography. Two weeks later, the eyeballs were removed and the apoptotic cells were determined by electron microscopy, TUNEL technique and flow cytometry in scleras. Both bFGF and the bcl-2 protein were determined by the immunohistochemisty method and the Western-blot method. Results: All eyes treated with -10.00D or -20.00D concave lens produced defocus-induced myopia.
