Abstract

Improved devices, systems, and methods for diagnosing, planning treatments of, and/or treating the refractive structures of an eye of a patient incorporate results of prior refractive corrections into a planned refractive treatment of a particular patient by driving an effective treatment vector function based on data from the prior eye treatments. The exemplary effective treatment vector employs an influence matrix which may allow improved refractive corrections to be generated so as to increase the overall accuracy of laser eye surgery (including LASIK, PRK, and the like), customized intraocular lenses (IOLs), refractive femtosecond treatments, and the like.
