Cataracts

In many places around the world, the simple operation to remove a cataract is unaffordable or inaccessible.

A cataract is a clouding of the lens of the eye. The lens is located near the front of the eye and it focuses on the retina, at the back of the eye, to form the image we see. A cataract may affect just a small part of the lens, or it may cloud the entire lens. Although not preventable, cataracts are treatable with a straightforward and inexpensive surgical procedure.

Cataracts remain the leading cause of blindness around the world, except for in developed countries such as Canada. Cataracts account for almost half of visual impairment.

There are many types of cataracts. Most are caused by a change in the chemical makeup of the lens. Certain medications (such as steroids), genetics, eye injuries or certain diseases can also cause cataracts.

  • Age-related cataracts are the most common, and they may occur as early as age 40.
  • Congenital cataracts appear in babies at birth. They may have been inherited or precipitated by a medical condition in the child’s mother.
  • Traumatic cataracts can occur in people of any age. This type of cataract is caused by an injury to the eye – such as a hard blow, puncture, intense heat or chemical burns – which damages the lens.
  • Certain diseases such as diabetes can also cause cataracts at an early age.

Operation Eyesight was founded in response to the need to treat cataracts, at what is today Arogyavaram Eye Hospital in Sompeta, India. We’ve been working there since 1963 and have made a great impact, thanks to people like you.
