Mathematic proof of Schachar's hypothesis of accommodation.
To evaluate whether there is increased or decreased zonular tension during accommodation, we developed a qualitative small displacement model using Rayleigh's method to determine the characteristics of the human lens changes that occur during accommodation. We found that the optical power of the human lens increased linearly with zonular tension. Our results definitely prove Schachar's hypothesis of accommodation.
