METHOD AND SYSTEM FOR EYE MEASUREMENTS AND CATARACT SURGERY PLANNING USING VECTOR FUNCTION DERIVED FROM PRIOR SURGERIES

摘要

Improved devices, systems, and methods for planning cataract surgery on an eye of a patient incorporate results of prior corrective surgeries into a planned cataract surgery of a particular patient by driving an effective surgery vector function based on data from the prior corrective surgeries. The exemplary effective surgery vector employs an influence matrix which may allow improved refractive corrections to be generated so as to increase the overall efficacy of a cataract surgery by specifying one or more parameters of an intraocular lens (IOL) to be implanted during the cataract surgery.

1. A method for planning a cataract surgery on an eye of a patient, the method comprising:
determining an effective treatment vector function based on a plurality of prior corrective surgeries by: for each prior corrective surgery on an associated eye:
defining a pre-surgery vector characterizing measured pre-surgery high-order aberrations of the associated eye,defining a post-surgery vector characterizing measured post-surgery high-order aberrations of the associated eye, andderiving the effective surgery vector function using a correlation between the pre-surgery vectors and the post-surgery vectors; defining an input vector based on measured pre-surgery high-order aberrations of the eye of the patient; and deriving one or more parameters of an intraocular lens (IOL) to be implanted into the eye of the patient by applying the effective surgery vector function to the input vector.
