Step-by-step explanation:
A posterior polar cataract is a specific type of cataract that forms at the back of the lens in the eye. It is characterized by a cloudiness or opacity that affects the posterior pole of the lens. This type of cataract can cause vision problems and may require surgical intervention to restore clear vision.
One of the main causes of a posterior polar cataract is genetic or inherited factors. It can also be associated with other eye conditions or trauma to the eye. The clouding of the lens in a posterior polar cataract can disrupt the passage of light and cause vision to become blurry or distorted.
