Cataract extraction and intraocular lens implantation in an infant with a monocular congenital cataract.

A cataract extraction and primary capsulotomy with intraocular lens (IOL) implantation was performed on a 17-day-old infant with a monocular mature congenital cataract. The IOL power, calculated at the time of surgery, was undercorrected to compensate for the growth of the eyeball. Two additional surgical procedures were required to resolve visual axis obstruction caused by lens epithelial cell proliferation. Follow-up was 18 months, during which amblyopia prevention therapy was instituted.
