Abstract:
The present disclosure concerns a curvature-changing, accommodative intraocular lens (IOL) that may be implanted in the capsular bag of a patients eye and is configured to harness the energy of the movement of the capsular bag upon contraction and relaxation of the ciliary muscles. In certain embodiments, the IOL includes a fluid optic body defining a cavity for containing an optical fluid, the cavity at least partially defined by a first optical membrane configured to extend across an optical axis of the patients eye. The IOL further includes a plurality of lever arms extending from the optic body and configured to be in contact with the capsular bag such that axial compression of the capsular bag causes each of the plurality of lever arms to rotate about a corresponding pivot so as to modify a curvature of the first optical membrane.
Abstract:
The invention relates to a combined eye implant (1) for implantation into a capsular bag (6) of the human or animal eye, in particular in the course of a cataract operation, the implant comprising: a substantially annular sensor implant (11), which surrounds a central cut-out section (3) and which has a pressure sensor (7) for measuring the intraocular pressure and microelectronics (8) for converting signals of the pressure sensor (7) into digital data and for transmitting this data to an external read-device via an antenna (9); and a lens implant (12), which, when implanted, at least partially covers the central cut-out section (3) of the sensor implant (11). In order to avoid mutual functional interference between the lens implant (12) and the sensor implant (11), according to the invention, the eye implant is improved by the provision of one or more retaining elements (13, 14) which secure the relative position of the sensor implant (11) to the lens implant (12) in an axial direction (2), allowing at least a minor relative displacement of the sensor implant (11) in relation to the lens implant (12) in a radial direction running orthogonally to the axial direction (2).
Abstract:
The present invention provides an ophthalmic lens adapted to provide extended depth of field and adapted to be positioned anywhere between the object and the retina of the eye, the lens comprising at least one optical element (1) having a first optical surface (2) adapted to be positioned on the anterior side of the optical element and a second optical surface (3) adapted to be positioned on the posterior side of the optical element, wherein said optical surfaces include at least one optical shape according to a polynomial of the fourth degree, wherein the arrangement is adapted to provide an optical function for a polynomial of the third degree providing said extension of depth of field.
Abstract:
An intraocular lens, and use thereof, the lens configured to reduce or eliminate oblique incident light photic disturbances in the eye, said lens comprising anterior and posterior surfaces defining a central lens optic extending from said anterior to said posterior surfaces and a peripheral portion outside of the central lens optic, wherein the peripheral portion is a prismatic lens which redirects oblique incident light on the peripheral portion forward of the nasal retina in the eye and onto the ciliary body/pars plana region.
Abstract:
Various intraocular pseudophakic contact lenses (100, 400, 800, 900, 1600, 1700, 1800, 1900, 2000) are disclosed. For example, an intraocular pseudophakic contact lens can include a first optical lens (102, 402, 802, 902, 1602, 1702, 1802, 1902, 2002, 2100, 2102, 2200, 2250, 2300, 2400) and multiple anchors (106a-106b, 406a-406b, 1500). The first optical lens is configured to at least partially correct a residual refractive error in an eye (1300). The anchors are configured to be inserted through an anterior surface of an intraocular lens (1000) into lens material (1006) forming a second optical lens (1002) of the intraocular lens in order to secure the intraocular pseudophakic contact lens to the intraocular lens. The anchors can be configured to couple the intraocular pseudophakic contact lens to different types of intraocular lenses, including intraocular lenses not specifically designed to be coupled to or receive the intraocular pseudophakic contact lens. The intraocular pseudophakic contact lens could also include at least one drug-eluting device (1706, 1806, 1906) located on the first optical lens and configured to deliver at least one medication.
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.
