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 multiple rings, with the rings having step heights corresponding to a desired performance of the optic and configured to reduce adverse optical effects of the diffractive profile.

Abstract: Systems and methods are provided for improving overall vision in patients suffering from a loss of vision in a portion of the retina (e.g., loss of central vision) by providing a dual optic intraocular lens which redirects and/or focuses light incident on the eye at oblique angles onto a peripheral retinal location. The intraocular lens can include a redirection element (e.g., a prism, a diffractive element, or an optical component with a decentered GRIN profile) configured to direct incident light along a deflected optical axis and to focus an image at a location on the peripheral retina. Optical properties of the intraocular lens can be configured to improve or reduce peripheral errors at the location on the peripheral retina. One or more surfaces of the intraocular lens can be a toric surface, a higher order aspheric surface, an aspheric Zernike surface or a Biconic Zernike surface to reduce optical errors in an image produced at a peripheral retinal location by light incident at oblique angles.

Abstract: The embodiments disclosed herein include improved toric lenses and other ophthalmic apparatuses (including, for example, contact lens, intraocular lenses (IOLs), and the like) and associated method for their design and use. In an embodiment, an ophthalmic apparatus (e.g., a toric lens) includes one or more angularly-varying phase members comprising a diffractive or refractive structure, each varying the depths of focus of the apparatus so as to provide an extended tolerance to misalignment of the apparatus when implanted in an eye. That is, the ophthalmic apparatus establishes an extended band of operational meridian over the intended correction meridian.

Abstract: Apparatuses, systems and methods for providing improved intraocular lenses (IOLs), include features for reducing side effects, such as halos, glare and best focus shifts, in multifocal refractive lenses and extended depth of focus lenses. Exemplary ophthalmic lenses can include a continuous, power progressive aspheric surface based on two or more merged optical zones, the aspheric surface being defined by a single aspheric equation. Continuous power progressive intraocular lenses can mitigate optical side effects that typically result from abrupt optical steps. Aspheric power progressive and aspheric extended depth of focus lenses can be combined with diffractive lens profiles to further enhance visual performance while minimizing dysphotopsia effects. The combination can provide an increased depth of focus that is greater than an individual depth of focus of either the refractive profile or the diffractive profile

Abstract: The intraocular aberration correction lens is shaped by an optical area that has a gradient in the chromatic dispersion value of the material or materials that shape it, in such way that said gradient is parallel to the optical axis. The net value of the chromatic dispersion in the anterior area of the lens is different from the value in its posterior area. For this, the use of a single material or various is possible. The anterior and posterior surfaces of the lens, as well as the separation between adjacent materials, if applicable, have a geometric shape so that the group comprising the intraocular lens and the eye that contains it display a correction, or significant reduction, of the optical aberrations, both the chromatic ones and the monochromatic ones on and outside the optical axis. The lens can be given areas with different optical powers in a way that enables clear and simultaneous vision at different distances.

Abstract: A method of designing a multifocal ophthalmic lens with one base focus and at least one additional focus, capable of reducing aberrations of the eye for at least one of the foci after its implantation, comprising the steps of: (i) characterizing at least one corneal surface as a mathematical model; (ii) calculating the resulting aberrations of said corneal surface(s) by employing said mathematical model; (iii) modelling the multifocal ophthalmic lens such that a wavefront arriving from an optical system comprising said lens and said at least one corneal surface obtains reduced aberrations for at least one of the foci. There is also disclosed a method of selecting a multifocal intraocular lens, a method of designing a multifocal ophthalmic lens based on corneal data from a group of patients, and a multifocal ophthalmic lens.

Abstract: A lens having an extended range of focus is made of a transparent material and has two optical surfaces. The lens defines an optical axis and a focal power distribution (Ftot) which, in relation to a plane perpendicular to the optical axis, changes as a function of the radial height (r) and of the azimuth angle (phi) of the aperture between a calculated basic value of the focal power (Flens) not equal to zero and a maximum value Fspiral max(r, phi).
