Pediatric cataract is one of the leading cause of childhood blindness. Cataract will cause a social and economical burden on the child and family if left untreated.

In cataract, the lens of the eye becomes opaque and causes cloudy vision.  The lens is situated behind the pupil. The pupil is a dark circle present in the centre of the eye. The natural lens allows the light to pass through it and get focused on the retina, a tissue present at the back of the eye.

A cataract is a condition in which the lens of the eye becomes cloudy. The lens of the eye focuses the image onto the retina. Then the brain gets the image  through the retina.

The first few months of life is a critical period of visual development. It becomes extremely important to treat cataract in early childhood.
