Abstract: Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs), include features for providing improved extended depth of focus lenses. Exemplary ophthalmic lenses can include an optic including a diffractive profile including at least one set of echelettes, each echelette of the set having a different width in r-squared space than any other echelette of the set and the at least one set of echelettes repeating at least once upon the optic.

Abstract: System and method for customizing multifocal ophthalmic lenses, such as an intraocular lens (IOL) or the like, that may be tailored for an individual patient or group of patients beyond the selection of a particular IOL power. One or more eye factors of the patient are determined, a set of different multifocal intraocular lenses having a similar base power are determined based on the eye factors, and a multifocal intraocular lens is selected for the patient from the set based on the eye factors.

Abstract: A system of ophthalmic lenses contains a first lens for a first eye of a subject and a second lens for a second eye of a subject. The first lens includes a first lens shape having a first base refractive power and a first diffractive pattern imposed on the first lens shape, the diffractive pattern having a first lower diffraction order with a first lower diffractive power and a first higher diffraction order with a first higher diffractive power. The first lens includes lower and higher optical powers equal to the first base refractive power plus the first lower and higher diffractive powers, respectively. The second lens includes a second lens shape having a second base refractive power and a second diffractive pattern imposed on the second lens shape, the second diffractive pattern having a second lower diffraction order with a second lower diffractive power and a second higher diffraction order with a second higher diffractive power.

Abstract: When fitting a patient for an intraocular lens, a series of measurements is taken on the patient's eye that determines a required lens power. Next, a range of preferred shape factors may be found, which determine the base (i.e., spherical) radii of the two lens surfaces, essentially independent of the lens power. The preferred shape factor adjusts the third-order coma of the lens to largely offset the coma of the cornea, so that the image at the retina has a reduced amount of third-order coma. Once a preferred shape factor is determined, the base radii of curvature of the anterior and posterior surfaces are determined from the shape factor and the lens power by algebraic formulas. Finally, one or more aspheric terms are added to one or both of the surfaces in the lens, so that the spherical aberration of the lens largely offsets the spherical aberration of the cornea.

Abstract: A method of designing an aspheric ophthalmic lens with both refractive and diffractive powers that is capable of reducing chromatic aberration and at least one monochromatic aberration of an eye comprises combining aspherical refractive and diffractive surfaces, selecting an appropriate eye model, establishing a design lens having at least one aspheric surface with a capacity to reduce monochromatic aberration in said eye model, establishing a diffractive lens element that corrects for chromatic aberration of the model eye; and adjusting the lens surface design in order to obtain a suitably high polychromatic image quality in a form that is weighted to comply with a spectral merit function.
