Abstract: A lens for use in an intraocular lens system for treating age-related macular degeneration (AMD), the lens including an anterior surface, a posterior surface, and a plurality of haptics configured to align the anterior light-converging intraocular lens with an optical axis of the eye. The plurality of haptics may have a symmetrical design and comprising ciliary-sulcus-engaging surfaces configure to position the lens within in a ciliary sulcus of an eye. At least one of the anterior surface and the posterior surface may be rendered as aspherical surfaces selected to induce spherical aberration while minimizing optical aberration and thereby provide for a continuum of retinal images to be focused at an area macula of a retina of the eye between two retinal eccentricities.

Abstract: An intraocular lens system comprising at least one intraocular lens having an anterior surface and a posterior surface, wherein at least one surface of the lens is aspherical to provide for a continuum of retinal images to be focused at the retina in an area between two retinal eccentricities. The system may include an anterior light-converging intraocular lens 16 for positioning within the eye, the anterior lens having an anterior surface and a posterior surface; and a posterior light-diverging intraocular lens 17 for positioning within the eye posterior to the anterior lens, the posterior lens having an anterior surface and a posterior surface; wherein one or both surfaces of the anterior lens and/or one or both surfaces of the posterior lens are aspherical.

Abstract: Intraocular lens and methods for optimization of depth of focus and the image quality in the periphery of the visual field.

Abstract: An intraocular lens system comprising: an anterior light-converging intraocular lens (16) for positioning within the eye, the anterior lens having an anterior surface and a posterior surface; and a posterior light-diverging intraocular lens (17) for positioning within the eye posterior to the anterior lens, the posterior lens having an anterior surface and a posterior surface; wherein the posterior lens is separate to the anterior lens; and wherein at least one of the surfaces of the anterior lens or surfaces of the posterior lens is a modified surface which includes a surface aberration which increases the depth of focus of the lens, optimises image quality and may also provide for a magnified image over a range of retinal eccentricities.

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.
