Aberration-guided Intraocular Lens Power Calculation in Keratoconus: Ray Tracing Optimization.

Bland-Altman analysis showed good agreement between ray tracing optimization-predicted and postoperative subjective refraction, particularly for spherical equivalent (spherical equivalent) and J0 (with/against-the-rule astigmatism).

Cataract surgery in keratoconic eyes did not induce significant variations in the corneal Zernike coefficients.

Ray tracing optimization accuracy was highest when vertical coma (Z3-1) predominated as the main higher-order aberration.
