    This study compared anterior segment measurements between Sirius Plus and Pentacam AXL in 80 myopic patients scheduled for refractive surgery.

  • 2

    Significant discrepancies were found in most anterior segment parameters, except for anterior flat keratometry and astigmatism measurements.

  • 3

    High intraclass correlation coefficients indicated strong consistency for anterior flat keratometry, steep keratometry, and white-to-white measurements.

  • 4

    Goodness-of-fit analysis showed R2 values greater than 0.85 for several parameters, confirming strong correlations between the two devices.

  • 5

    The study supports the use of anterior corneal keratometry and white-to-white as reliable reference points in clinical practice.
