Children with congenital cataracts do not usually regain normal vision after surgery, and the prognosis for vision after treatment varies from child to child. Children with congenital cataracts may experience symptoms such as decreased vision, nystagmus, and in severe cases, strabismus. After surgery, the child’s vision does not return to normal. Under normal circumstances, after birth, children need light to enter the fundus of the eye and stimulate the retina to further develop before their vision can become clearer and clearer. Most children with congenital cataracts have amblyopia, which affects the development of vision because light cannot pass through the cataract to stimulate the fundus of the eye. After surgery, children need refractive correction and amblyopia training to improve their vision, but it is usually difficult to return to the level of normal peers. It is recommended that children after cataract surgery should follow the doctor’s instructions, have regular checkups and seek medical attention when discomfort occurs.
