Capsular Outcomes of Pediatric Cataract Surgery With Primary Intraocular Lens Implantation (capsular)

March 12, 2021 updated by: Yune Zhao

Capsular Outcomes of Pediatric Cataract Surgery With Primary Intraocular Lens

Lens capsular often changes after pediatric cataract surgery，causing complications such as anterior capsulerhexis shrinkage, visual axis opacification (VAO), zonular dehiscence and so on. The aim of study was to prospectively investigate the capsular outcomes of pediatric cataract surgery with primary intraocular lens (IOL) implantation.

Detailed Description

To investigate the capsular outcomes from a case series of children who underwent cataract surgery and primary IOL implantation at the Eye Hospital of Wenzhou Medical University between 2016 and 2019. Took Digital retro-illumination photographs of pediatric eyes at baseline and 6 months, 12 months, and the last visit postoperatively. Compare the capsular outcomes of the posterior capsule opening (PCO) area and visual axis transparent area at those time points, and analysis the correlations between the PCO area and influential factors, such as age at surgery, axial growth, and follow-up duration.

Cohorts and Interventions

Group / Cohort
pediatric cataract group
Children who underwent cataract surgery and primary IOL implantation at the Eye Hospital of Wenzhou Medical University (Hangzhou, China) between 2016 and 2019 were included in the study. Every surgery included posterior capsulorhexis or capsulotomy and anterior vitrectomy. Patients accept slit-lamp-adapted anterior segmental photography at 1 week, 2 weeks, 1 month, 3 months, and 6 months postoperatively.
