Abstract:
An intraocular lens derivation system comprising:an eye surface measurement device for measuring an anterior segment of a patient's eye including an anterior and posterior corneal surface of the eye; an eye length measurement device for measuring an axial length of the eye, a crystalline lens thickness and position, and a corneal thickness; an eye modeler connected to each of the measurement devices for deriving a model of the eye based on the measured anterior and posterior corneal surfaces, the measured crystalline lens thickness and position, the measured axial length, the corneal thickness, and an IOL model; an IOL database for providing a technical description of the IOL model for use in the eye modeler; an optical evaluator for evaluating a plurality of eye models each including the model of a different IOL; and a metric for determining the success of the optical evaluation.
