Comparative study of the biophysical changes in senile, complicated and congenital cataracts

Refractive index, electrophoretic mobility and protein content of the soluble lens proteins were studied in senile, complicated, and congenital cataracts. In senile cataract, the refractive index and protein content showed remarkable decrease accompanied with significant increase in the electrophoretic mobility. Obtained results of complicated cataract demonstrated marked fluctuations as compared with the healthy controls. Refractive index and the soluble protein content in congenital cataract showed general decrease while the electrophoretic mobility revealed slight increase
