Corrective intraocular lens and associated methods

摘要

A system for providing improved vision to a patient having undergone an intraocular lens implantation includes a device for measuring an aberration in an eye of a patient having an intraocular lens implanted therein. Computer software is resident on a processor and is adapted to calculate a refraction profile prescription for correcting the measured aberration. An apparatus is also provided for altering a refractive index of a sector of the intraocular lens in situ according to the calculated prescription. The method includes measuring an aberration in an eye of a patient having an intraocular lens implanted therein, calculating a refraction profile prescription for correcting the measured aberration, and altering a refractive index of a sector of the intraocular lens in situ according to the calculated prescription.
