  • Publication number: 20180153681
    Abstract: A system, method, and apparatus are provided for designing and evaluating intraocular lenses for a large field of view that generate a first eye model from data that includes constant and customized values, including customized values of a first intraocular lens. A simulated outcome is provided by the first intraocular lens in at least one modeled eye. A second eye model is generated wherein a second intraocular lens is substituted for the first intraocular lens. An outcome provided by the second intraocular lens is simulated in at least one modeled eye. Outcomes of the first and second intraocular lenses are compared.

  • Publication number: 20180073958
    Abstract: A system and method of characterizing through-focus visual performance of an IOL using metrics based on an area under the modulation transfer function for different spatial frequencies at different defocus positions of the IOL. Also disclosed is a system and method of characterizing through-focus visual performance of an IOL using a metric based on an area under a cross-correlation coefficient for an image of a target acquired by the IOL at different defocus positions of the IOL.

  • Publication number: 20170258578
    Abstract: Lenses and methods are provided for improving peripheral and/or central vision for patients who suffer from certain retinal conditions that reduce central vision or patients who have undergone cataract surgery. The lens is configured to improve vision by having an optic configured to focus light incident along a direction parallel to an optical axis at the fovea in order to produce a functional foveal image. The optic is configured to focus light incident on the patient's eye at an oblique angle with respect to the optical axis at a peripheral retinal location disposed at a distance from the fovea, the peripheral retinal location having an eccentricity between ?30 degrees and 30 degrees. The image quality at the peripheral retinal location is improved by reducing at least one optical aberration at the peripheral retinal location. The method for improving vision utilizes ocular measurements to iteratively adjust the shape factor of the lens to reduce peripheral refractive errors.

  • Publication number: 20170245987
    Abstract: Apparatuses, systems and methods for providing improved intraocular lenses (IOLs), include features for reducing side effects, such as halos, glare and best focus shifts, in multifocal refractive lenses and extended depth of focus lenses. Exemplary ophthalmic lenses can include a continuous, power progressive aspheric surface based on two or more merged optical zones, the aspheric surface being defined by a single aspheric equation. Continuous power progressive intraocular lenses can mitigate optical side effects that typically result from abrupt optical steps. Aspheric power progressive and aspheric extended depth of focus lenses can be combined with diffractive lens profiles to further enhance visual performance while minimizing dysphotopsia effects. The combination can provide an increased depth of focus that is greater than an individual depth of focus of either the refractive profile or the diffractive profile.
