Posterior Capsule Opacification Management in Ophthalmology
Summary
Posterior capsule opacification (PCO) remains the principal long-term complication of cataract surgery, arising from the proliferation and migration of residual lens epithelial cells across the posterior capsule. Clinically, PCO manifests as reduced visual acuity, contrast sensitivity loss and glare. Standard management comprises neodymium-doped yttrium aluminium garnet (Nd:YAG) laser capsulotomy to restore the visual axis, but carries risks of intraocular pressure spikes, retinal detachment and macular oedema. Preventive strategies have evolved towards refinements in intraocular lens (IOL) design—particularly optic edge configuration and biomaterial selection—to inhibit cell adhesion and migration. Emerging approaches include surface modifications of IOLs, pharmacological coatings for controlled drug delivery and light-triggered therapies. A comprehensive grasp of the cellular mechanisms, global epidemiology and device innovations is vital to optimise outcomes and reduce the burden of retreatment worldwide.

Technical terms
Posterior Capsule Opacification (PCO): Clouding of the posterior lens capsule caused by postoperative proliferation and migration of residual lens epithelial cells.
Intraocular Lens (IOL): An artificial lens implanted within the capsular bag to replace the natural crystalline lens after cataract extraction.
Nd:YAG Capsulotomy: A non-invasive laser procedure that creates an aperture in the opacified posterior capsule to restore the visual axis and improve acuity.
