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 piggyback lens which in combination with the cornea and an existing lens in the patient's eye redirects and/or focuses light incident on the eye at oblique angles onto a peripheral retinal location. The piggyback 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 piggyback lens can be configured to improve or reduce peripheral errors at the location on the peripheral retina. One or more surfaces of the piggyback 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.

Methods for treating presbyopia in a patient's eye involve inducing spherical aberration in a central area of the pupil. In embodiments, refractive properties of an eye are measured to obtain a baseline refractive correction. A lens for wearing on the eye is provided to create spherical aberration or a distribution of spherical aberrations beyond the baseline refractive correction in the central area of the pupil. The central area of the pupil has a diameter of between 1.5 mm and 4.0 mm and has negligible spherical aberration without the treatment.

Certain aspects of the present disclosure provide a transposable intraocular lens (IOL), which includes a lens body, including a first lens portion having a first outer surface with a first radius of curvature, a second lens portion having a second outer surface with a second radius of curvature that is different from the first radius of curvature, and a central optic portion between the first lens portion and the second lens portion, and a haptic portion that is coupled to the lens body. The transposable IOL also includes a haptic portion configured to support the transposable IOL whether in a first orientation of implantation in a patient’s eye or in a transposed second orientation of implantation in the patient’s eye.

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.

The present disclosure relates to devices, systems, and methods for improving or optimizing peripheral vision. In particular, methods are disclosed which include utilizing particular characteristics of the retina in improving or optimizing peripheral vision. Additionally, various IOL designs, as well as IOL implantation locations, are disclosed which improve or optimize peripheral vision.

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 symmetric or asymmetric optic with aspheric surface 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.

Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs), include features for reducing dysphotopsia effects, such as haloes and glare. Exemplary ophthalmic lenses may include a central zone with a first set of two echelettes arranged around the optical axis, the first set having a profile in r-squared space. A middle zone includes a second set of two echelettes arranged around the optical axis, the second set having a profile in r-squared space that is different than the profile of the first set. A peripheral zone includes a third set of two echelettes arranged around the optical axis, the third set having a profile in r-squared space that is different than the profile of the first set and the profile of the second set, the third set being repeated in series on the peripheral zone.

Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs). Exemplary diffractive intraocular implants (IOLs) can include a diffractive profile having multiple diffractive zones. The diffractive zones can include a central zone that includes one or more echelettes and a peripheral zone beyond the central zone having one or more peripheral echelettes. The central diffractive zone can work in a higher diffractive order than a remainder of the diffractive profile. The combination of the central and peripheral zones and an optional intermediate zone provides a longer depth of focus than a diffractive profile defined just by a peripheral and/or optional intermediate zone.

An intraocular lens is disclosed that includes an optic body with a projection extending radially outwards from a peripheral surface of the optic body. The projection comprises a haptic contact surface facing radially outward, wherein the entire haptic contact surface is a flat surface. A haptic having a free distal end and a proximal portion is secured to the projection along the haptic contact surface, wherein the projection and the proximal portion interface at a butt joint without the haptic extending into the projection and without the projection extending into the haptic. The haptic also includes a haptic fluid chamber.

Multifocal intraocular lens with extended depth of field that comprises, in at least one of the surfaces (2), a small zone with a multifocal profile with a defined optical axis (3) and, in the peripheral region and coaxial to the multifocal zone, a ring-shaped opaque mask (1) that partially or totally block light to produce a small aperture effect and, therefore, the multifocal profile has a radius equal or larger than the internal radius of the mask (1), and there is at least one transition between focal zones or one diffractive step inside the internal radius of the mask (1).
