Cataracts are one of the most treatable causes of visual impairment du
ring infancy. Recent epidemiological studies have shown that they have
a prevalence of 1.2 to 6.0 cases per 10,000 infants. The morphology o
f infantile cataracts can be helpful in establishing their etiology an
d prognosis. Early surgery and optical correction have resulted in an
improved outcome for infants with either unilateral or bilateral catar
acts. While contact lenses continue to be the standard means of optica
lly correcting an infant's eyes after cataract surgery intraocular len
ses are gaining in popularity as an alternative means of optically cor
recting these eyes. Post-operative complications occur more commonly a
fter infantile than adult cataract surgery and many of these complicat
ions do not develop until years later. As a result, it is critical tha
t children be followed closely on a long term basis after infantile ca
taract surgery.
