Do congenital cataracts in children need removing?

Congenital cataracts, caused by a genetic defect or illness in the mother during pregnancy, do not always require cataract surgery. 

If the congenital cataract affects the periferal, outer edge of the lens children will retain central vision and may not need surgery. Likewise, small cataracts do not always need to be removed. 

If cataract extraction surgery is performed, not all children are suitable for intraocular lenses. If an IOL is not placed after the cataract is removed, children will need to wear glasses after surgery.

If a multifocal or monofocal lens is used to replace the damaged lens in children, it is likely that this lens will need replacing as the child develops.
