Posterior capsular Opacification: Pathogenesis, challenges, and innovative therapeutic strategies

Area of Science:

• Ophthalmology
• Cell Biology
• Biomedical Engineering

Background:

• Posterior capsular opacification (PCO) is a significant complication following cataract surgery.
• It results from the proliferation and migration of residual lens epithelial cells (LECs).
• Despite advances, PCO remains a prevalent issue affecting visual acuity.

Purpose of the Study:

• To review current research on the cellular and molecular mechanisms of PCO.
• To explore novel therapeutic strategies for preventing and treating PCO.
• To bridge the gap between basic science findings and clinical applications.

Main Methods:

• Review of existing literature on PCO pathogenesis.
• Analysis of cellular processes including LEC proliferation, migration, and epithelial-mesenchymal transition (EMT).
• Examination of molecular factors such as oxidative stress, extracellular matrix accumulation, and inflammation.

Main Results:

• PCO pathogenesis involves complex cellular and molecular pathways.
• Key mechanisms include LEC proliferation, migration, EMT, oxidative stress, and inflammation.
• Current research highlights various innovative therapeutic avenues.

Conclusions:

• Further research into PCO pathogenesis is crucial.
• Translating foundational discoveries into clinical practice is essential for improving patient outcomes.
• Future strategies may involve IOL modifications, pharmacological treatments, and gene therapy.
