Abstract
A method of manufacturing an intraocular lens that has been customized to provide optimum vision for an eye with prior corneal refractive surgery. Such a custom manufactured IOL will address not only optical correction requirements as currently met by spherical or toric-shaped IOLs, but will correct higher order optical aberrations using needed optimum customized shapes.
Claims16
A method of manufacturing a customized intraocular lens, comprising the steps of:
- a) selecting a group of patients having undergone a common prior corneal refractive surgical procedure for correcting a similar refractive error;
- b) collecting data on the shape of each eye in the group of patients;
- c) analyzing the data collected on the shape of each eye in the group of patients;
- d) calculating an optimized prescription for an intraocular lens for each group of patients;
- and
- e) manufacturing the intraocular lens according to the optimized prescription.

A method of manufacturing a customized intraocular lens system, comprising the steps of:
- a) implanting a primary intraocular lens in an eye of a patient;
- b) collecting data on the eye postoperatively following implantation of the primary intraocular lens;
- c) analyzing the data collected on the post operative eye following implantation of the primary intraocular lens;
- and
- d) calculating an optimized prescription necessary to achieve a targeted lower order and minimized higher order aberrations in the eye for a supplementary intraocular lens;
- e) manufacturing the supplementary intraocular lens according to the optimized prescription;
- and
- f) implanting the supplementary intraocular lens in the eye.
