  • Proposal of design criteria for future prevalence studies.

    • Main Results:

    • Comparability is a critical, yet often overlooked, property in prevalence studies.
    • Specific design criteria can enhance the ability of studies to detect risk factors.
    • Standardized approaches are needed for accurate cataract prevalence assessment.

    Conclusions:

    • Standardized and comparable cataract prevalence studies are vital for accurate global health assessments.
    • Well-designed studies are crucial for identifying modifiable and non-modifiable risk factors.
    • Future research should prioritize methodological consistency to improve data reliability.
