Impact of Age-Related Changes in Lens Shape on the Increased Risk of Posterior Capsule Opacification Observed in Pediatric Cataract Patients.

ABSTRACT:

Purpose

Posterior capsule opacification (PCO) rates are higher in young cataract patients compared to adults, a phenomenon attributed to a higher proliferative potential of young lens epithelial cells (LECs). This study investigates the hypothesis that implanting standard (adult-sized) intraocular lenses (IOLs) in pediatric patients, whose lenses are smaller and more spherical, results in a low contact between the IOL and the posterior lens capsule (PLC), thus contributing to elevated pediatric PCO rates.

Methods

Simulated PLCs (sPLC) modeling the size and curvatures of human lenses of eight-year-old (8y-sPLC), 25-year-old (25y-sPLC), and 65-year-old (65y-sPLC) individuals were fabricated. The physical interactions between standard IOL and the sPLCs were quantified using opt
