Correction of higher order aberrations in intraocular lenses

摘要

In one aspect, the present invention provides a method of designing an intraocular lens (IOL) to address variations of at least one ocular parameter in a population of patient eyes. The method can include establishing at least one eye model in which the ocular parameter can be varied over a range exhibited by the population. The eye model can be employed to evaluate a plurality of IOL designs in correcting visual acuity for eyes in the patient population. An IOL design that provides a best fit for visual performance over at least a portion of the parameter range can then be selected.

主权项

1. An intraocular lens (IOL) comprising an optic, the optic comprising an anterior surface and a posterior surface, the optic being manufactured by the process of:
establishing at least one eye model in which the ocular parameter can be varied over a range exhibited by the population, employing the eye model to evaluate a plurality of IOL designs for visual performance for eyes in the patient population, applying a weighting function to visual performance exhibited by the plurality of IOL designs, said function being based on distribution of the ocular parameter in the population, selecting an IOL design that provides a best fit for visual performance over at least a portion of the range exhibited by the population; and manufacturing at least one IOL according to the selected IOL design.
