Eye Lens and Cataract Trends

Abstract

Karan Aggarwala and Maciej Czepita

In this paper we present facts on the ocular lens, and its loss of transparency, which after some time, is termed as cat- aract. We touch upon cataract caused by environmental toxins: mercury in particular, and some clinical physiology. Conclusive proof on steroid-induced cataract does not exist at the time of this writing. Trends on frequency of eye surgery by geographic region, and the tendency to wait upon first diagnosis-- or to remove the cataract urgently, are not meant to suggest it is unethical, instead, it is epidemiology.
