Complications Occurring Through 5 Years Following Primary Intraocular Lens Implantation for Pediatric Cataract

IMPORTANCE: Lensectomy with primary intraocular lens (IOL) implantation is often used in the management of nontraumatic pediatric cataract, but long-term data evaluating the association of age and IOL location with the incidence of complications are limited. OBJECTIVE: To describe the incidence of complications and additional eye surgeries through 5 years following pediatric lensectomy with primary IOL implantation and association with age at surgery and IOL location. DESIGN, SETTING, AND PARTICIPANTS: This prospective cohort study used Pediatric Eye Disease Investigator Group cataract registry data from 61 institution- and community-based practices over 3 years (June 2012 to July 2015). Participants were children younger than 13 years without baseline glaucoma who had primary IOL implantation (345 bilateral and 264 unilateral) for nontraumatic cataract. Data analysis was performed between September 2021 and January 2023. EXPOSURES: Lensectomy with primary IOL implantation. MAIN OUTCOME AND MEASURES: Five-year cumulative incidence of complications by age at surgery (
