Background:

Assessing corneal geometry post-refractive surgery is crucial for understanding outcomes.
Current methods using standard corneal topography may have limitations in accuracy.
Laser-assisted in situ keratomileusis (LASIK) is a common refractive surgery procedure.

Purpose of the Study:

To evaluate the reliability of an intrinsic corneal reference system for characterizing post-LASIK corneas.
To compare corneal parameters derived from the intrinsic system versus standard topographer data.
To improve the accuracy of corneal geometry characterization in refractive surgery patients.

Main Methods:

Analysis of data from 90 eyes that underwent LASIK for myopia and astigmatism correction.

Calculation of corneal curvature radii and asphericity using an intrinsic corneal reference system.

Comparison of these parameters with those obtained directly from a corneal topographer.

Main Results:

The intrinsic reference system provides better characterization of corneal geometry.
Corneal parameters derived from the intrinsic system exhibit lower variability.
Discrepancies between experimental and predicted values are significantly reduced (21% mean relative error vs. 81%).

Conclusions:

An intrinsic corneal reference system offers a more reliable method for corneal characterization after refractive surgery.
This approach enhances the understanding of corneal geometry and reduces prediction errors.
The findings are essential for improving the precision and outcomes of refractive surgery.
