Combined wavefront and topography systems and methods

摘要

Methods, software, and systems are provided for determining an ablation target shape for a treatment for an eye of a patient. Techniques include determining wavefront information from the eye of the patient with a wavefront eye refractometer, determining anterior corneal shape information from the eye with a corneal topography device, and combining the wavefront information and the anterior corneal shape information to determine the ablation target shape.

主权项

1. A method for determining an ablation target shape for a laser vision treatment for an eye of a patient, comprising:
determining a desired wavefront or wavefront gradient value for the eye of the patient; determining a measured wavefront or wavefront gradient value of the eye of the patient with a wavefront measurement system; determining an anterior corneal shape or anterior corneal shape gradient value of the eye of the patient with a corneal topography device; and combining the desired wavefront or wavefront gradient value, the measured wavefront or wavefront gradient value, and the anterior corneal shape or anterior corneal shape gradient value to determine the ablation target shape.
