Definitions
- the invention is an intraocular lens with associated auxiliary devices, with which a patient regains the ability to optically close-up (accommodation) through or after the operation of the natural eye lens.
- Intraocular lenses as they correspond to the state of the art, normally only allow sharp vision at exactly one distance.
- intraocular lenses with two or more focal lengths (“multifocal lenses”) have been known for several years and thus allow a sharp vision at several distances. Since several images are superimposed out of focus, the contrast with these lenses is significantly worse than with a monofocal lens. It is only possible to see sharply at certain distances, the intermediate area is much less clear, so it is not possible to see with these lenses as with natural accommodation.
- Systems in which the refractive power of the intraocular implant can be adjusted by external measures, represent an intermediate step in the direction of accommodation.
- the optical elements can be shifted on the optical axis, for example, by changing the head position by means of gravity or by magnetic forces (US5326347A, US5593437A).
- a magnetic layer is applied to the intraocular lens, and the lens is moved by an adjustable magnet that sits in a kind of glasses in front of the eye.
- the displacement on the optical axis is carried out by means of a screw thread, the screwing process being carried out with magnetic tools from outside the eye.
- intraocular lenses are commercially available, the outer part (haptic) of which is designed as a resilient hinge, so that a radial contraction is deflected into an axial displacement (WO9615734A2).
- haptic the outer part of which is designed as a resilient hinge, so that a radial contraction is deflected into an axial displacement
- WO9615734A2 the outer part of which is designed as a resilient hinge, so that a radial contraction is deflected into an axial displacement
- the capsular bag after removing the inside of the lens, the capsular bag shrinks and hardens individually.
- the capsular bag can therefore not be used as an element of any kind of movement process that can be calculated in terms of its mechanical parameters.
- the spring force of the zonular fibers via which the capsular bag is suspended elastically from the ciliary muscle, shows considerable inter-individual fluctuations.
- the posterior capsule of the lens will become cloudy (night star). This clouded part must then be removed, for example with a laser
- the object of the present invention is to make an intraocular lens available which changes its position in the axial direction on contraction of the ciliary muscle.
- the postoperative shrinkage of the capsular bag, the variation in the spring force of the zonular fibers and a later removal of the rear, central part of the capsule (capsulotomy) should not significantly affect the function of the accommodation process.
- the intraocular implant which is to be inserted into the capsular bag in a known manner, contains an artificial lens in known technology and in its peripheral part permanent magnets, which are arranged on a circle with the optical axis of the eye as a circle normal (hereinafter referred to as "inner magnets") inner magnets opposite are also attached to the sclera on a circle further outward, the circle normal of which is again the optical axis of the eye, (hereinafter referred to as "outer magnets").
- Inner and outer magnets are polarized so that they repel each other, and geometrically aligned so that this repulsion exerts a forward force on the capsular bag and thus on the intraocular lens located therein.
- the strength of the forward force can be individually adjusted to the desired accommodation success by choosing the strength, number, geometry and location of the outer magnets.
- the accommodation as a function of the magnetic force is measured with the aid of electromagnets whose strength can be adjusted and known optical measuring means.
- This adjustment of the outer magnets should therefore preferably take place at a point in time at which the shrinkage of the capsular bag has largely been completed, that is to say only a few months after the lens and the inner magnets have been implanted in the capsular bag.
- the implant to be inserted into the capsular bag consists of any rear capsule lens with a central optic and preferably loop feel in known and proven technology, and a capsule clamping ring also in known and proven technology.
- the inner magnets are cast into the capsule clamping ring.
- the magnets must be completely surrounded by biocompatible material.
- the ring can have cavities between the inner magnets.
- the outer magnets can be designed as bar magnets, surrounded by biocompatible material, whereby pre-assembled eyelets, notches or threads facilitate precise positioning and sewing.
- the external magnets are preferably sewn on from the outside onto the sclera under the conjunctiva. In principle, they can also be attached inside the eye in the area of the pars plana. The latter is cheaper in terms of magnetic forces, but the operational risk is significantly higher.
- electromagnets are integrated into a ring, which is placed on the eye from the outside during the measurement.
- the electromagnets must be polarized in the same way as the outer magnets. They should also be located at the same location as possible when the permanent magnets to be sewn on. Alternatively, the magnetic forces must otherwise be converted using known rules of electrodynamics.
- the success of the accommodation can be determined with known means of objective or subjective refraction determination (autorefractor, phoropter, placing minus glasses or nearby objects) or with known measuring methods for determining the position of the intraocular lens (interferometer, ultrasound) as a function of the magnetic repulsive force and the relaxation and relaxation of the ciliary muscle triggered by the patient either voluntarily or by medication.
- the inner magnets are integrated into the haptics of the intraocular lens.
- loop haptics for example with C or J loops using known technology
- the magnets can be inserted into the ends of the loops.
