Abstract

PURPOSE:

Wavefront-guided laser refractive surgery induces postoperative optical aberrations that are not explained by the ablation profile.

METHODS:

A conceptual model is presented for a potential mechanism of surgically-induced corneal shape change that is dependent on structural modification, rather than ablation profile.

RESULTS:

Examples are provided from clinical and basic studies that are consistent with the proposed model.

CONCLUSION:

Corneal biomechanical response to ablative surgery may significantly affect outcomes, and should be taken into account when planning customized procedures.
