Devices and methods for replacing a human lens after cataract surgery. The device is an insert for the eye capsule and is formed of two or more rings that are connected to one another. A primary lens is affixed to the insert. A secondary add-in lens can be added to the insert in a subsequent surgery to correct, or further optimize, the optical results obtained with the initial surgery.

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.

A method of performing laser surgery in a patient's eye includes generating a light beam, deflecting the light beam using a scanner to form an enclosed treatment pattern that is configured to form an enclosed capsulorhexis incision that includes a registration feature, and delivering the enclosed treatment pattern to target tissue in the patient's eye to form in an anterior lens capsule of the patient's eye the enclosed capsulorhexis incision that includes the registration feature. The registration feature is configured so that an edge of the target tissue formed by the enclosed capsulorhexis incision mates with an intraocular lens registration feature on an intraocular lens so as to rotationally register the intraocular lens relative to the registration feature.

A prosthetic capsular device configured to be inserted in an eye after removal of a lens, in some embodiments, can comprise a housing structure comprising capable of containing an intraocular device and an equiconvex refractive surface. The housing structure can comprise an anterior portion comprising an anterior opening, a posterior portion comprising a posterior opening, and a continuous lateral portion between the anterior portion and the posterior portion.

An accommodating intraocular lens (IOL) can be implanted either alone or as part of a two-part lens assembly. The IOL comprises an optic, a flexible membrane and a peripheral edge coupling the optic and the flexible membrane. The peripheral edge comprises an external circumferential surface having a height and a force transmitting area defined along a portion of the height of the external circumferential surface. A closed volume spaces apart the optic and the flexible membrane. The optic is axially displaced and the flexible membrane changes in curvature about a central axis when a radial compressive force is applied to the force transmitting area. A volume defined by the closed volume remains fixed when the optic is axially displaced and the flexible membrane changes in curvature and/or when the radial compressive force is applied to the force transmitting area.

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.

Provided is an intraocular lens having an optical body and having at least one haptic element coupled to the optical body, wherein the at least one haptic element has a first haptic component and at least a second haptic component formed adjacent thereto, which is movable elastically relative to the first haptic component, and having a principal optical axis that penetrates through a front side and a reverse side of the optical body, wherein the haptic element, measured in the direction of the principal optical axis, has a maximum of a first height, wherein the second haptic component is displaceable relative to the first haptic component from a non-spread position to a spread position in such a way that the haptic element, measured in the direction of the principal optical axis, attains a maximum of a second height which is greater than the first height, and, in the spread position, the second haptic component can be locked in place relative to the first haptic component, wherein the first haptic component has at least a first spreading element, and the second haptic component has at least a second spreading element, wherein the first spreading element and the second spreading element, viewed in circumferential direction around the principal optical axis, at least in the spread position, are in a mutually overlapping arrangement and directly adjacent to one another at least in some regions.
