From the weight of the lenses of patients with senile cataract, ultrasonic measurements of the eyes of patients with acute diabetic refractive changes, and calculations on the basis of Legrand's theoretical eye, it appears that the conclusion can be drawn that these refractive changes are due to alterations in the refractive indices of the lens.
通过对老年性白内障患者晶状体重量的研究、对急性糖尿病性屈光变化患者眼睛的超声测量以及基于勒格兰德理论眼的计算,似乎可以得出这样的结论:这些屈光变化是由于晶状体折射率的改变所致。
