Infant Aphakia Treatment Study (IATS)

Congenital Cataract

The primary purpose is to determine whether infants with a unilateral congenital cataract are more likely to develop better vision following cataract extraction surgery if they undergo primary implantation of an intraocular lens or if they are treated primarily with a contact lens. In addition, the study will compare the occurrence of postoperative complications and the degree of parental stress between the two treatments.
