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: 20230350232Abstract: Certain embodiments are directed to lenses, devices and/or methods. For example, a lens for an eye having an optical axis and an aberration profile along its optical axis, the aberration profile having a focal distance and including higher order aberrations having at least one of a primary spherical aberration component C(4,0) and a secondary spherical aberration component C(6,0). The aberration profile may provide, for a model eye with no aberrations and an on-axis length equal to the focal distance: (i) a peak, first retinal image quality (RIQ) within a through focus range that remains at or above a second RIQ over the through focus range that includes said focal distance, where the first RIQ is at least 0.35, the second RIQ is at least 0.1 and the through focus range is at least 1.8 Diopters; (ii) a RIQ of 0.3 with a through focus slope that improves in a direction of eye growth; and (iii) a RIQ of 0.3 with a through focus slope that degrades in a direction of eye growth.Type: ApplicationFiled: March 31, 2023Publication date: November 2, 2023Inventors: Ravi Chandra Bakaraju, Klaus Ehrmann, Arthur Ho

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
