Types Of Cataracts

Cataracts can be classified based on where and how they develop in the eye. They are divided into the following categories:

• Nuclear Cataracts

  This type of cataract forms in the middle of the lens and causes the nucleus to turn brown or yellow.

• Cortical Cataracts

  They are wedge-shaped cataract types that form around the edges of the nucleus.

• Posterior capsule cataracts

  They form faster than the other two types and affect the back of the lens.

• Congenital Cataracts

  Congenital cataracts are the cataract types that are present at birth or develop during a baby’s first year and are less common than age-related cataracts.

• Secondary Cataracts

  Secondary cataracts are caused by diseases or medications such as glaucoma and diabetes. The use of the steroid prednisone and other medications can sometimes lead to cataracts.

• Traumatic Cataracts

  They are aftereffects of an eye injury. This type usually takes several years to develop.

• Radiation Cataracts

  Radiation cataracts can form after a person undergoes radiation treatment for cancer.

There are different types of cataracts. They’re classified based on where and how they develop in the eye. They are nuclear cataracts, cortical cataracts, posterior capsular cataracts, congenital cataracts, secondary cataracts, and radiation cataracts.
