To compare the differences, consistencies, and correlations of anterior segment biological parameters measured by Sirius Plus and Pentacam AXL in a healthy myopic population.
Key Findings:
No significant differences in anterior flat keratometry, anterior vertical/horizontal astigmatism, and anterior oblique astigmatism at 45° between the two devices.
Significant differences were observed in other parameters, including central corneal thickness and anterior chamber depth.
Intraclass correlation coefficients for anterior flat keratometry, anterior steep keratometry, and white-to-white were 0.965, 0.963, and 0.932, respectively.
Goodness-of-fit analysis showed R2 values >0.85 for several key parameters, indicating strong correlation.
Interpretation:
The study indicates that anterior corneal keratometry and white-to-white measurements are consistent and reliable between the two devices, suggesting their effective use in clinical practice for refractive surgery.
Limitations:
The study was limited to a specific population (myopic patients) and may not generalize to other populations, potentially affecting the applicability of the results.
Only one eye per participant was measured, which may affect the overall data representation and limit the robustness of the findings.
Conclusion:
Sirius Plus and Pentacam AXL provide comparable measurements for certain anterior segment parameters, suggesting their suitability for clinical applications in refractive surgery.
