  • Publication number: 20240050276
    Abstract: A method of altering a refractive property of a crosslinked acrylic polymer material by irradiating the material with a high energy pulsed laser beam to change its refractive index. The method is used to alter the refractive property, and hence the optical power, of an implantable intraocular lens after implantation in the patient's eye. In some examples, the wavelength of the laser beam is in the far red and near IR range and the light is absorbed by the crosslinked acrylic polymer via two-photon absorption at high laser pulse energy. The method also includes designing laser beam scan patterns that compensate for effects of multiphone absorption such as a shift in the depth of the laser pulse absorption location, and compensate for effects caused by high laser pulse energy such as thermal lensing. The method can be used to form a Fresnel lens in the optical zone.

  • Publication number: 20240050223
    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: 20230365227
    Abstract: Systems and methods for evaluating ND are described herein. An example method can include constructing a non-sequential (NSC) ray-tracing model of an eye with an ophthalmic lens, and modelling a light source and a detector. The detector can be configured to mimic a retina of the eye. The method can also include computing irradiance data using the light source, the NSC ray-tracing model, and the detector. Irradiance data can be computed for each of a plurality of pupil sizes. The method can further include evaluating ND by analyzing the respective irradiance data for each of the pupil sizes. Also described herein are methods for designing an ophthalmic lens edge that reduces the incidence of ND for a given ophthalmic lens by adjusting the edge thickness and/or the scatter.

  • Patent number: 11504226
    Abstract: Intraocular lenses for reducing the risk of posterior capsule opacification (PCO) are described herein. PCO can be reduced with an IOL design that increases the pressure at the posterior capsular bend, for example, by including a sharper edge design, an enlarged optical zone, and/or an increased vault height. An example ophthalmic lens can include an optic (200) including an anterior surface (202) defining an anterior side of the optic, a posterior surface (204) defining a posterior side of the optic, and an edge (210) arranged between the anterior and posterior surfaces. The edge and the posterior surface can form an angle, where the angle is less than about 90 degrees. Additionally, the ophthalmic lens can have an increased vault height. At least one of the angle or the increased vault height be configured to increase pressure on a capsular bend in a subject's eye.
