Abstract: Systems and methods for providing improved techniques for evaluating performance of intraocular lenses. Such techniques can be used to evaluate lens designs and can help reduce the need for multiple clinical trials that may otherwise be needed to evaluate multiple design iterations. In one embodiment, a method is provided for method for evaluating performance of an intraocular lens, where the method comprises capturing a plurality of images through the intraocular lens at different focus positions; displaying at least one selected image from the plurality of images to a test subject; receiving input from the test subject indicative of perceived acuity of the at least one selected image; and determining a measure of intraocular lens performance from the received input.

Abstract: A method of selecting a toric lens by taking into consideration the magnitude and orientation of the posterior cornea and/or the location of the incision axis is described. The magnitude and orientation of the posterior cornea can be calculated as a function of the measured pre-operative orientation of the steep meridian of the anterior cornea.
