    The study validated a regression-based keratometric prediction model for refractive outcomes in pterygium-affected eyes post-cataract surgery.

  • 2

    A paired analysis of 20 unilateral eyes showed significant differences in keratometric methods, but no significant difference between postoperative K and predicted K.

  • 3

    Sensitivity analyses confirmed consistent findings, indicating the reliability of the regression model for predicting refractive outcomes.

  • 4

    Preoperative corneal characteristics may influence refractive predictability, suggesting the need for careful assessment before surgery.

  • 5

    The findings support the clinical utility of prediction-based keratometry, although larger prospective studies are needed for confirmation.
