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 a plurality of echelettes, each echelette of the diffractive profile having a different width in r-squared space than any other echelette of the diffractive profile and each echelette of the diffractive profile being configured to distribute light to a distance focus.

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.

An intraocular implant for implantation in an iris of the eye is disclosed. The intraocular implant may include a tubular member at least partially formed of a shape memory material to enable the tubular member to transition between a first shape and a second shape. The tubular member may have a first retaining element, a second retaining element, a shaft portion extending between the first and second retaining portions, and at least one lumen extending therethrough. The shaft portion of the tubular member may have a length substantially equal to or less than a thickness of the iris. The shaft may have a smaller cross-section than the first and second retaining elements when the tubular member is in the second state.

A lens including a posterior surface, an anterior surface, and at least one identification marking on the lens. The at least one identification marking exhibits a first degree of visibility in an ambient lighting condition and a second degree of visibility greater than the first degree of visibility in a lighting condition different than the ambient lighting condition.

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.

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.

Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs). Embodiments may include a shift of a diffractive order.

An apparatus uses optical components arranged as a telescope to simulate the optical effects of intraocular lenses on images viewed in the presence of scattering light and glare sources. By simulating a view of a real image through an intraocular lens and projecting the simulated view into a patient's eye, the patient can view the quality of vision that may result from use of a particular lens as a corrective tool. The intraocular lens is placed within the fields of view of peripheral optical components having prescribed operating parameters that allow for projecting a simulated image through an intraocular lens into a patient's eye before the intraocular lens is implanted. The patient can perceive the results of a corrective lens before that lens is attached to or implanted within the patient's eye.

A system and method for efficiently modifying the surface of an intraocular lenses to reduce tackiness and improve lens unfold time and unfold time consistency, and a product created using the system and method, is disclosed. In some embodiments, the system and method utilizes at least part of a lens-forming device as a mask.

Lenses and methods are provided for improving peripheral and/or central vision for patients who suffer from certain retinal conditions that reduce central vision or patients who have undergone cataract surgery. The lens is configured to improve vision by having an optic configured to focus light incident along a direction parallel to an optical axis at the fovea in order to produce a functional foveal image. The optic is configured to focus light incident on the patient's eye at an oblique angle with respect to the optical axis at a peripheral retinal location disposed at a distance from the fovea, the peripheral retinal location having an eccentricity between −30 degrees and 30 degrees. The image quality at the peripheral retinal location is improved by reducing at least one optical aberration at the peripheral retinal location. The method for improving vision utilizes ocular measurements to iteratively adjust the shape factor of the lens to reduce peripheral refractive errors.
