|20120323321||Intraocular Lenses for Variable Focus - A novel lens for variable focus has two optical elements which simultaneously move in a lateral and an axial direction. The lens also includes variable corrective optics to correct for undesired variable optical aberrations. The lens can be used as an accommodating lens for implantation in the capsular bag. The lens can be driven by either the surfaces of the capsular bag as well as the rim of the capsular bag.||12-20-2012|
|20120323320||ADJUSTABLE INTRAOCULAR LENS - An adjustable intraocular lens is disclosed comprising at least one optical element and at least one haptic. Rotation of the lens in a plane perpendicular to the optical axis and bounded by an oval boundary adjusts the lens diameter which provides a corresponding adjustment of optical power. Preferably the lens according to the invention is adapted to be manipulated by manipulation means outside the eye, for example, surgical means. Adjustment of the angular position of the intraocular lens results in a corresponding adjustment of the lens diameter which, in turn, leads to a corresponding adjustment of the optical power of the lens.||12-20-2012|
|20120310341||Accommodative Intraocular Lens Driven by Ciliary Mass - The invention relates to an intraocular accommodative lens, comprising an optical arrangement and haptics, the lens being adapted for variable focusing by movement of at least one part of the optical arrangement by at least one of the haptics, wherein the haptics comprise a part adapted to transfer a movement from the ciliary mass to the optical arrangement. This forms an attractive way of driving the variable lens, in particular for locations of the lens avoiding the capsular bag.||12-06-2012|
|20120257278||Optics with Simultaneous Variable Correction of Aberrations - The invention refers to an optical system comprising at least two optical elements of which at least one is movable relative to the other in a direction perpendicular to the optical axis of the optical system, wherein the combination of optical elements is adapted to correct variable aberrations of at least two different orders simultaneously of which the degree of correction depends on the relative position of the optical elements. This optical system is adapted to correct aberrations which are variable and dependent on the position of the lens with respect to the subject/imaging plane. Further the optical system is adapted to correct aberrations varying along with defocus of the system. These aberrations may include second order aberrations, meaning defocus and astigmatism, third-order aberrations, meaning comas and trefoils, fourth-order aberrations, for example, spherical aberration, and further higher-order aberration terms.||10-11-2012|

|20100280609||ADJUSTABLE ACCOMMODATING INTRAOCULAR LENS AND POSITIONING MEANS - An accommodating intraocular artificial lens with variable optical power, comprising two optical elements which are adapted to mutually shift in a direction perpendicular to the optical axis wherein the optical elements have such a shape that the optical elements exhibit, in combination, different optical powers at different relative positions. Flanges are adapted to position the anterior section of the haptics in the sulcus of the eye or, alternatively, the ciliary body is enclosed by a combination of anterior and posterior flanges. Also disclosed are methods to provide for an accommodating intraocular lens which is adjustable post-implant to ensure emmetropia of the eye.||11-04-2010|

At least two of the optical elements of the lens comprise at least one additional optical correction surface, which correction surfaces are adapted for simultaneous variable correction of one or more optical aberrations of the natural eye in which the degree of correction depends on the relative position of the optical elements.||04-15-2010|
|20090062912||Construction of an Intraocular Artificial Lens - This invention concerns an intraocular artificial lens with variable optical power which lens is comprised of two optical elements which can be shifted relatively to each other in a direction perpendicular to the optical axis wherein the optical elements have such a shape that they exhibit, in combination, different optical powers at different relative positions and positioning means for positioning the optical elements in the eye and driving means for at least one of the optical elements to execute a movement relative to the other optical element and whereby the positioning means provide for forcing the optical elements to a resting position.||03-05-2009|
|20090024214||INTRA-OCULAR ARTIFICIAL LENS WITH VARIABLE OPTICAL STRENGTH - An intra-ocular artificial lens with variable optical strength, having at least two optical elements, at least two of which are movable relative to each other in a direction extending transversely of the optical axis, wherein the optical elements have a form such that in different positions of the movable optical elements the artificial lens has a different optical strength, wherein the artificial lens has a fixed, positive optical basic strength wherein the variable optical strength caused by the relative movement of the movable elements is added to obtain the total optical strength of the artificial lens. Providing a different form results in the possibility of incorporating the greatest optical power in one of the optical elements. This optical element can then be optimized for the desired optical properties. The remaining optical element or the remaining optical elements can then be dimensioned for variation of the optical strength.||01-22-2009|
|20080215146||Intra-Ocular Artificial Lens for Iris-Driven Accommodation - An intra-ocular artificial lens with variable optical strength, wherein the artificial lens comprises two optical elements which are movable relative to each other in a direction extending transversely of the optical axis, wherein the optical elements have a form such that in different relative positions they together have different optical strengths, wherein the movable optical elements are connected to positioning means which are adapted for coupling to the iris of the eye for the purpose of driving. This measure makes use of the fact that one or both of the optical elements can be displaced relative to each other through the driving of the natural orbicularis muscle of the iris in order to obtain an accommodating function.||09-04-2008|
