Types of Cataracts

There are different types of cataracts. They’re classified based on where and how they develop in your eye.

    Type of Cataract
  • Nuclear cataracts form in the middle of the lens and cause the nucleus, or the center, to become yellow or brown.
  • Cortical cataracts are wedge-shaped and form around the edges of the nucleus.
  • Posterior capsular cataracts form faster than the other two types and affect the back of the lens.
  • Congenital cataracts, which are present at birth or form during a baby’s first year, are less common than age-related cataracts.
  • Secondary cataracts are caused by disease or medications. Diseases that are linked with the development of cataracts include glaucoma and diabetes. The use of the steroid prednisone and other medications can sometimes lead to cataracts.
  • Traumatic cataracts develop after an injury to the eye, but it can take several years for this to happen.
  • Radiation cataracts can form after a person undergoes radiation treatment for cancer.
