To determine the physical effect of a change in the equatorial lenticular diameter on optical power, sclera-ciliary bodies of bovine eyes were stretched radially. The effective optical power and lenticular equatorial diameter were measured. We found that an increase in the equatorial diameter of the bovine lens produced an increase in its effective optical power. Our results directly contradict Helmholtz's hypothesis of accommodation and its modifications. These results support Schachar's hypothesis of accommodation, which states that there is increased zonular tension during accommodation.
为了确定赤道部晶状体直径变化对屈光力的物理影响，对牛眼的巩膜 - 睫状体进行径向拉伸。测量有效屈光力和晶状体赤道直径。我们发现牛晶状体赤道直径的增加会导致其有效屈光力增加。我们的结果直接与亥姆霍兹调节假说及其修正观点相矛盾。这些结果支持沙查尔调节假说，该假说认为在调节过程中悬韧带张力增加。
