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

  • 2

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

  • 3

    In vitro assays demonstrated that metformin significantly attenuates lens epithelial cell proliferation compared to controls.

  • 4

    The findings suggest that metformin use may modify PCO risk, challenging previous epidemiological data on diabetes and PCO.

  • 5

    The authors advocate for larger studies to explore metformin as a potential adjunct treatment for preventing PCO.
