APPLICATION OF BLEND ZONES, DEPTH REDUCTION, AND TRANSITION ZONES TO ABLATION SHAPES

摘要

Methods, devices, and systems for reprofiling a surface of a cornea of an eye ablate a portion of the cornea to create an ablation zone with an optically correct central optical zone disposed in a central portion of the cornea, and a blend zone disposed peripherally to the central optical zone and at least partially within an optical zone of the eye. The blend zone can have an optical power that gradually diminishes with increasing radius from the central optical zone.
