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.

Abstract: A system for determining a vision treatment for an eye of a patient is provided which includes a memory and a processor, in communication with the memory, configured to receive a first treatment target corresponding to a first target shape of a surface of the eye, obtain a periphery modification function (PMF), determine a second treatment target corresponding to a second target shape of the surface of the eye by multiplying, for each of a plurality of points on the surface of the eye, the PMF by the first treatment target, and scale the second treatment target using a scaling factor such that values of the second treatment target are scaled to be greater at a mid-periphery of the eye and scaled to be lower at a far-periphery of the eye. A treatment parameter of a treatment applied to the surface of the eye is controlled by the scaled second treatment target.

Abstract: A method of selecting a tonic 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.

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.
