Problems solved by technology

Therefore, it is often difficult to find universally valid, well-functioning biomechanical devices that are equally suitable for the many individual differences in the human population and additionally also for the temporal variations of the biomaterials used for this function
To make matters worse: the properties of the biomaterials used for this function cannot usually be measured before cataract surgery, which is why it is not possible to adapt to individual conditions
[0005] Additionally, conventional IOL implants often must dilate the native capsular bag to reduce / avoid fibrosis, which requires large implant volumes and makes small incision sizes difficult

Embodiment Construction

[0048] figure 1 A schematic view of an eye 10 with an implanted intraocular lens system 30 (IOL system) according to a preferred embodiment is shown in a longitudinal section along a section plane (left) and a cross-sectional view perpendicular to the optical axis 100 (right). side), wherein the optical axis 100 of the eye 10 extends in said cross-sectional plane.

[0049] The cornea 12 and iris 14 of the eye 10 are identified from the longitudinal cross-sectional view of the eye 10, along with the underlying ciliary body 16, ribbon fibers 18 and empty capsular bag 22, and where the natural lens 20 is disposed, but all The natural lens has been removed from the eye in the described embodiment.

[0050] figure 1 Also vertically bisected, wherein the upper part of the longitudinal and cross-sectional views respectively shows the eye 10 in the first accommodation state and the lower part shows the eye in the second accommodation state 10. For example, the state shown in the u...

Abstract

The invention relates to an intraocular lens system (30) for implantation in an eye (10). The intraocular lens system (30) comprises a ciliary body implant (32) having a ciliary body magnet element (36), the ciliary body implant (32) being implantable in the eye (10) such that the ciliary body magnet element (36) follows at least partially a movement of a ciliary body (16) of the eye (10). The intraocular lens system (30) also includes an intraocular lens (10) having a lens magnet element (44). In this case, the ciliary body implant (32) and the intraocular lens (34) are formed separately from one another and the intraocular lens system (30) is designed to control the refractive effect of the intraocular lens (34) by means of an interaction in the eye (10) between the ciliary body magnet element (36) and the lens magnet element (44). The invention also relates to a ciliary body implant (32) and an intraocular lens (34).

Description

technical field [0001] The present invention relates to intraocular lens systems, intraocular lenses and ciliary implants. Therefore, the present invention is based in particular in the field of intraocular lenses, especially biomechanically accommodating intraocular lenses and ophthalmic surgery. Background technique [0002] In the prior art, intraocular lenses (IOLs) with biomechanical accommodation are known, ie the refractive effect of the IOL can be varied by applying mechanical force by means of muscle tissue and can be adapted to the desired accommodation. [0003] IOLs are usually implanted in the capsular bag of the eye because of the low complication rate compared to other implantation sites and the sophistication of the required surgical techniques, where there are numerous designs of such biomechanical IOLs. Designs known in the prior art use the natural trigger force for accommodation, ie the change in diameter of the ciliary body or ciliary muscle, only indir...
