Agreement of anterior corneal aberrations between a Placido-disk-based wavefront analyzer and a Scheimpflug system in myopic candidates for refractive surgery

Key Points

• The systems showed moderate correlations but could not replace one another for accurate measurements.
• Correlation metrics in Zernike terms indicate some level of agreement, yet critical differences remain.
• Observational analysis compared a Placido-disk-based wavefront analyzer to a Scheimpflug system in myopic candidates.
• Implications suggest tailoring patient selection for refractive surgeries based on specific corneal aberrations.
