TECHNIQUE FOR TREATING PRESBYOPIA

摘要

A system and method for reshaping a cornea of a patient's eye to treat presbyopia are disclosed as well as a method of generating a computer program for use in such system. Ray tracing is used to determine an ablation pattern that defines an amount of corneal tissue to be ablated, wherein the ablation pattern achieves a pre-defined amount of at least one of sphere, spherical aberration, coma, and astigmatism in the eye.

1. A method of determining a corneal ablation pattern for treating presbyopia of a human eye, comprising:
defining a non-zero amount of induced aberration for a presbyopic human eye; and applying a ray tracing process to determine a corneal ablation pattern defining an amount of corneal tissue that, when removed from the eye, leaves the eye with the defined amount of induced aberration.
