摘要:
The present invention relates to an intraocular lens, in particular capsular intraocular lens, with at least an anterior, a posterior optic element, a haptic element connecting both optic elements, wherein a cavity is formed by the optic element, and haptic elements, which are opened by circumferentially arranged openings. The object of the present invention is to provide an intraocular lens that allows a symmetrical deformation of one or more optic elements of the intraocular lens as well as a relative displacement of these optic elements relative to each other on their optic elemental axis, so that a sufficient change in refractive power is obtained. This object is met by an intraocular lens, wherein it is provided that the area of the cavity between the optic elements comprises a filling that is at least partially enclosed by a membrane thata) is formed as a bag and completely encloses the filling,b) is ring-shaped and is connected to the anterior and posterior optic element orc) closes the openingsThe present invention further relates to an intraocular lens having at least an anterior and a posterior optic element and a haptic element interconnecting both optic elements. According to the invention the haptic element forms an overhang at the transition to the anterior optic element, wherein the anterior surface of the haptic element anterior extends beyond the edge of the anterior optic element or the haptic element forms an overhang at the transition to the posterior optic element, whereby the posterior surface of the haptic element posterior protrudes over the edge of posterior optic element, wherein the anterior or the posterior optic element is preferably embodied as a pinhole.
