Purpose: To determine the effect of age at penetrating keratoplasty (PKP) on graft survival and visual outcome in children with corneal opacities transplanted during infancy.
Methods: In this two-center retrospective consecutive cohort study, the medical records of infants who underwent unilateral or bilateral PKP during the first year of life between 2004 and 2011 were reviewed retrospectively. PKP was categorized as early (age 0-90 days) or late (age 91-365 days).
