Abstract: An accommodating intraocular lens (AIOL) construction having optics (2) and haptic (1) connected with the optics for positioning the optics within the eye, wherein the introcular lens construction is made of a single material having spatially-distributed different elasto-mechanical properties, and the elasto-mechanical properties of the haptic differ from the elasto-mechanical properties of the optics. The haptic and the optics made from the same polymer material, i.e., having the same molecular constituency. The optical power of the lens construction can change along with change in the shape of the haptic and intraocular lens construction. The haptic is shaped such that compression along the circumference of the haptic increases the optical strength of the optics.

Abstract: The invention relates to a device for measuring the optical properties of an eye, comprising an optical signal generator and optical guide means leading from the optical signal generator in the direction of the eye to be examined, wherein the optical signal generator is adapted to project an image through an optical path comprising the optical guide means and onto a reflective structure in the eye to be examined, wherein the device is adapted to couple the optical guide means of the device to optical guide means of an optical medical instrument so that the optical path extends through the optical guide means of the optical medical instrument. Such an optical medical instrument can be formed by an operating microscope, a so-called split lamp or by a fundus camera.

Abstract: 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.

Abstract: An intraocular lens comprising a central optical element (5) and at least two haptics (1) positioned in a plane perpendicular to the optical axis of the eye, wherein at least one haptic has a substantially ?-shaped structure adapted to be compressed in a direction perpendicular to the optical axis, and wherein the optical surfaces of the central optical element are smooth over their full areas. Two ?-shaped spring-like haptics (6) with different flexibility may be combined with these features resulting in an accommodating lens when the haptics are mechanically coupled to a structure of the eye subject to movements like the sulcus or the capsular bag.

Abstract: An accommodating intraocular lens with variable optical power, comprising at least two optical elements, at least one of which is movable relative to the other in a direction perpendicular to the optical axis, wherein the optical elements form a lens with different optical power at different relative positions of the optical elements. 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
