Cataract Treatment in India

Cataract is caused by clouding in the natural lens of human eyes. This lens lies behind the iris and the pupil and is one of the major causes of vision loss in human beings.

TYPE OF CATARACT

Different types of cataract are as follows

  • subcapsular cataract occurs at the back of the lens. People with diabetes or those taking high doses of steroid medications have a greater risk of developing a subcapsular cataract.
  • nuclear cataract forms deep in the central zone (nucleus) of the lens. Nuclear cataracts usually are associated with aging.
  • cortical cataract is characterized by white, wedge-like opacities that start in the periphery of the lens and work their way to the center in a spoke-like fashion. This type of cataract occurs in the lens cortex, which is the part of the lens that surrounds the central nucleus.
