Publication number: 20240126102Abstract: A contact lens and a method for treating an eye with myopia is described. The contact lens includes an inner optic zone and an outer optic zone. The outer optic zone includes at least a portion with a first power, selected to correct distance vision. The inner optic zone has a relatively more positive power (and add power). In some embodiments the add power is substantially constant across the inner optic zone. In other embodiments the add power is variable across the inner optic zone. While in some embodiments the inner optic zone has a power designed to substantially eliminate lag of accommodation in the eye with myopia, in other embodiments, the add power may be higher.Type: ApplicationFiled: September 21, 2023Publication date: April 18, 2024Inventors: Brien Anthony Holden, Gregor Schmid, Padmaja Rajagopal Sankaridurg, Arthur Ho, Aldo Abraham Martinez Magos, Percy Fabian Lazon, Earl Leo Smith, III

Patent number: 11809024Abstract: The present disclosure is directed to lenses, devices, methods and/or systems for addressing refractive error. Certain embodiments are directed to changing or controlling the wavefront of the light entering a human eye. The lenses, devices, methods and/or systems can be used for correcting, addressing, mitigating or treating refractive errors and provide excellent vision at distances encompassing far to near without significant ghosting. The refractive error may for example arise from myopia, hyperopia, or presbyopia with or without astigmatism. Certain disclosed embodiments of lenses, devices and/or methods include embodiments that address foveal and/or peripheral vision. Exemplary of lenses in the fields of certain embodiments include contact lenses, corneal onlays, corneal inlays, and lenses for intraocular devices both anterior and posterior chamber, accommodating intraocular lenses, electro-active spectacle lenses and/or refractive surgery.Type: GrantFiled: February 9, 2021Date of Patent: November 7, 2023Assignee: Brien Holden Vision Institute LimitedInventors: Ravi Chandra Bakaraju, Klaus Ehrmann, Arthur Ho, Brien Anthony Holden

Publication number: 20230097873Abstract: A contact lens for use in controlling or retarding the progression of myopia in an eye has a central optical zone approximating the normal diameter of the pupil of the eye that gives clear central vision at distance for the wearer. An annular peripheral optical zone that is substantially outside the diameter of the pupil is formed around the central optical zone with greater refractive power than that of the central zone so that oblique rays entering the eye through the peripheral optical zone will be brought to focus at a focal plane that is substantially on or anterior to the peripheral region of the retina. Preferably, the rear surface of the lens is shaped to conform to the cornea of the eye and the front surface of the lens is shaped to provide—in conjunction with the rear surface—the desired optical properties of the central and peripheral optical zones.Type: ApplicationFiled: September 1, 2022Publication date: March 30, 2023Inventors: Brien Anthony Holden, Arthur Ho, Padmaja Rajagopal Sankaridurg, Thomas Arthur Aller, Earl Leo Smith

Publication number: 20220072768Abstract: According to one aspect, there is provided a method of selectively solidifying successive layers of build material in a 3D printing system. The method comprises obtaining data relating to a 3D object to be generated, forming a layer of build material on a build platform, applying to the formed layer a pattern of fusing agent corresponding to a portion of the layer to be solidified to form a layer of the object, applying to the formed layer a pattern of anti-caking agent on portions of the formed layer that are not to be solidified to form a layer of the object, and applying energy to the whole of the formed layer to cause portions of the layer on which fusing agent was applied to heat up, melt, coalesce, and then solidify upon cooling, and to cause portions of the formed layer on which anti-caking agent was applied to control caking of build material in those portions.Type: ApplicationFiled: May 29, 2019Publication date: March 10, 2022Applicant: Hewlett-Packard Development Company, L.P.Inventors: Stan E.

Publication number: 20210379830Abstract: In an example implementation, a method of 3D printing includes receiving a 3D object model that defines the shape of an object to be printed in a layer-by-layer build process, and determining a desired thermal profile based on the shape of the object. For each object layer, a fusing energy radiation pattern is determined based on the desired thermal profile, and an electromagnetic energy emitter array is controlled to deliver fusing energy to the object layer according to the energy radiation pattern.Type: ApplicationFiled: February 26, 2019Publication date: December 9, 2021Applicant: Hewlett-Packard Development Company, L.P.Inventors: David Champion, Anthony Holden, Andrew L.

Publication number: 20210132413Abstract: An ophthalmic lens element includes an upper distance viewing zone and a lower near viewing zone. The upper distance viewing zone includes a central region with a first refractive power for clear distance vision and peripheral regions that are relatively positive in power compared to the first refractive power. The lower near viewing zone has a central region that is relatively positive in power compared to the first refractive power to account for accommodative lag. The powers of the peripheral regions of the lower near viewing zone are one of: i) equal to the power of the central region of the lower near viewing zone, ii) relatively positive in comparison to the power of the central region of the lower near viewing zone.Type: ApplicationFiled: October 20, 2020Publication date: May 6, 2021Inventors: Padmaja Rajagopal Sankaridurg, Cathleen Fedtke, Leslie Alan Donovan, Earl Leo Smith, II, Arthur Ho, Brien Anthony Holden
