What is a congenital cataract?

A congenital cataract is a cataract, clouding of the eye lens, that is present at birth.

Congenital cataracts can be a result of a genetic abnormality, have no identifiable cause or can be triggered by illness in the mother during pregnancy. Congenital cataracts that are likely to impair vision can be removed with cataract extraction surgery after the child is 16 weeks old.
