Types of Congenital Cataracts and Its Causes

A cataract is known to be the clouding of the lens of the eye that occurs later in life. If it is present at birth, it is called a congenital cataract.

Cataract surgery may be recommended to prevent amblyopia and blindness in infants but it depends on the location of the opacification and density.

There are some cases of congenital cataracts that affect only a small part of the lens which does not become a hindrance in normal vision to warrant surgery.

It is good timing to remove cataract while the child is an infant to promote normal vision development. There are experts who suggest that the optimal time to remove cataracts is 6 weeks and 3 months.

It is important to discuss the timing to remove the congenital cataract with eye surgeons as a parent to be aware of what to do. After cataract surgery, vision correction is advised because, without it, it can impede the vision development of the infant. It can be in the form of a surgically implanted intraocular lens (IOL), contact lens, or eyeglasses.
