There are certain differences that are unique to each type of cataract, resulting in the need for a classification system. Ophthalmologists generally identify the different types of cataracts according to two criteria: location and origin.

Cataracts Classified by Location Several types of cataracts are classified based on the location of the clouding of the eye's lens:Nuclear sclerotic - This type of cataract forms near the center of the lens, also called its nucleus. It causes a gradual yellow clouding and hardening of the central portion of the lens. This is the most common location for cataract formation.Cortical - This type of cataract develops on the outer portion of the lens, called the cortex. It looks like spokes of a wheel which shoot towards the center of the lens, scattering light that passes through the cataracts.
