Pediatric cataract is the most common treatable cause of blindness in children. Prevalence, etiology and morphology vary with the socioeconomic development. The treatment goal is to reduce amblyopia, being difficult management especially in unilateral cases. The decision on aphakia or primary intraocular lens should be individualized as well as correction with contact lens or spectacles. The intraocular lens single-piece hydrophobic acrylic are the most implanted in children and the preferably is in the capsular bag. The Sanders-Retzlaff-Kraff theoretic (SRK/T) stressing […]

A catarata pediátrica é a causa mais comum de cegueira tratável em crianças. Prevalência, etiologia e morfologia variam conforme o desenvolvimento sócioeconômico. O tratamento tem como objetivo diminuir a ambliopia, sendo de difícil manejo principalmente em casos unilaterais.
