    Metformin may reduce the incidence of posterior capsule opacification (PCO) after cataract surgery, a common long-term complication.

  • 2

    A study found that metformin accumulates in the human lens capsule, correlating with serum concentrations in patients with type 2 diabetes.

  • 3

    In vitro assays showed that metformin significantly attenuates lens epithelial cell (LEC) proliferation, a key factor in PCO development.

  • 4

    The findings suggest that metformin use may modify PCO risk, potentially explaining conflicting epidemiological data regarding diabetes.

  • 5

    The authors advocate for larger studies to further explore metformin's role as a pharmacological adjunct in PCO prevention.
