Paper Abstract

As the crystalline lens ages and as cataracts develop, highly concentrated proteins in lens fiber cells undergo rearrangements leading to substantial increases in scattered light. By exploiting a relationship between scattered light and refractive index, it is shown that a rearrangement of proteins necessarily leads to increased index as well. This change in refractive index is a second-order effect and must be quite small in most cases. However, it offers a possible explanation for the increase in index and refractive power associated with the development of nuclear cataract.
