    Posterior capsule opacification (PCO) after cataract surgery is caused by lens epithelial cells migrating and producing collagen. In vivo microscopy reveals these cells

    Area of Science:

    • Ophthalmology
    • Cell Biology

    Background:

    • Posterior capsule opacification (PCO) is a common complication after extracapsular cataract extraction (ECCE).
    • It results from the proliferation and migration of lens epithelial cells (LECs) onto the posterior capsule.

    Observation:

    • This study utilized high-magnification, in vivo specular microscopy to examine human posterior capsules post-ECCE.
    • The in vivo observations were correlated with established histopathologic findings of opacified posterior capsules.

    Findings:

    • Lens epithelial cells migrate onto the posterior capsule and exhibit myoblastic features.
    • These cells produce collagen and basement membrane, leading to fibrotic opacities and wrinkling.
    • Cellular contraction contributes to visual distortion.

    Implications:

    • In vivo specular microscopy is a valuable tool for studying PCO.
    • This technique can aid in evaluating treatments aimed at preventing or managing PCO.
