Abstract

The artificial lens, as an implant within the eyeball, has a thin envelope (1) filled with a transparent material (2). The lens envelope has radial hooks (3) to secure the lens to the ring-shaped opening remaining when the natural lens has been removed, to fit the lens into the eye. The actions of the ciliary muscles around the lens implant exert various pull strengths on the lens to give a variable refracting power, by altering the curvature radii of the lens envelope. The envelope is of a thin, transparent and biologically compatible synthetic material.

Description

Es ist bekannt, die im Auge vorhandene natürliche oder künstliche Linse unter möglichst weit­ gehender Erhaltung des Kapselsacks operativ zu entfernen, wenn wegen ihrer Eintrübung oder falschen optischen Brechwirkung die optische Funktion nicht hinreichend gewährleistet ist, und sie durch eine künstliche Linse geeigneter Brechkraft zu ersetzen, die mittels flexibler Bügel im Kapselsack zentriert ist (ISO 11979).It is known to take the natural or artificial lens in the eye as far as possible surgical preservation of the capsular bag to remove if because of its cloudiness or incorrect optical refractive effect, the optical function is not adequately guaranteed, and to replace them with an artificial lens of suitable refractive power, which is used in the Capsular bag is centered (ISO 11979).

Nach der Implantation einer solchen künstlichen Linse ist Akkommodation nicht oder nur in ge­ ringem Ausmaß möglich.After the implantation of such an artificial lens, accommodation is not or only in ge small extent possible.

Der im Patentanspruch 1 aufgeführten Erfindung liegt das Problem zugrunde, die Brechkraft der implantierten Intraokularlinse durch die mechanische Wirkung der Ziliarmuskeln zu verändern und Akkommodation zu ermöglichen.The invention listed in claim 1 is based on the problem, the refractive power of implanted intraocular lens to change by the mechanical action of the ciliary muscles and to enable accommodation.

Dieses Problem wird durch die im Patentanspruch 1 aufgeführten Merkmale, dass die Intraokular­ linse aus einer flexiblen und mit flexiblem Material derart gefüllten Hülle besteht, dass sich eine Linsenform geeigneter Brechkraft ergibt, wobei die Hülle an ihrer Peripherie mit Haken versehen ist, mit denen sie an einem mit den Ziliarmuskeln verbundenen Rest des Kapselsacks, der nach operativer Entfernung des zentralen Bereichs des Kapselsacks erhalten bleibt, befestigt werden kann, gelöst.This problem is caused by the features listed in claim 1 that the intraocular lens consists of a flexible sleeve filled with flexible material in such a way that a Lenticular shape results in a suitable refractive power, the envelope being provided with hooks on its periphery with which they are attached to a remainder of the capsular bag connected to the ciliary muscles operative removal of the central area of the capsular bag is retained can, solved.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung 1 dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing 1 and is in the following described in more detail.

Fig. 1 zeigt schematisch eine Aufsicht, Fig. 2 einen Schnitt durch eine Ausführungsform der Erfindung. Die Linse besteht aus einer biologisch verträglichen und dauerhaft transparenten und flexiblen Kunststoffhülle (1) und ist mit einer ebenfalls flexiblen und dauerhaft transparenten Sub­ stanz (2) gefüllt. Am Umfang der Linse ist diese mit Haken (3) versehen, die zur Befestigung der Linse im Auge und insbesondere zur Übertragung der Kraft des Ziliarmuskels des Auges dienen. Fig. 1 shows schematically a top view, Fig. 2 shows a section through an embodiment of the invention. The lens consists of a biologically compatible and permanently transparent and flexible plastic cover ( 1 ) and is filled with an equally flexible and permanently transparent substance ( 2 ). On the periphery of the lens, this is provided with hooks ( 3 ) which are used to fasten the lens in the eye and in particular to transmit the force of the ciliary muscle of the eye.

Vor dem Einsetzen der Linse entfernt der Operateur die natürliche Augenlinse und den zentra­ len Bereich des Kapselsacks. Die entsprechend der Erfindung angefertigte Linse wird anschließend in das Auge eingeführt und mit den Haken an dem ringförmigen Rest des Kapselsacks so befestigt, dass die Variation der Anspannung des Ziliarmuskels die radiären Zugkräfte auf die flexible Linse verändert und diese damit verformt. Die Form der Linsenhülle, insbesondere die Krümmungsra­ dien von Vorder- und Rückfläche, und der Brechungsindex der in der Linse vorhandenen Substanz werden zweckmäßigerweise so gewählt, dass die Linse im Auge die gewünschte brechende Wir­ kung hat. Zudem werden zweckmäßigerweise die Flexibilitäten der Linsenhülle und der eingefüll­ ten Substanz derart sein, dass die vom Ziliarmuskel bewirkte Variation der radiären Zugkraft die Linse derart verformt, dass die gewünschte akkommodative Brechkraftänderung entsteht.Before inserting the lens, the surgeon removes the natural eye lens and the center len area of the capsular bag. The lens made according to the invention then becomes inserted into the eye and attached to the ring-shaped remainder of the capsular bag with the hooks, that the variation in the tension of the ciliary muscle the radial tensile forces on the flexible lens changed and deformed it. The shape of the lens shell, especially the curvature serve the front and back surface, and the refractive index of the substance present in the lens are expediently chosen so that the lens in the eye has the desired refractive we kung has. In addition, the flexibility of the lens cover and the fill is expedient substance should be such that the variation in the radial pull caused by the ciliary muscle The lens is deformed in such a way that the desired accommodative change in refractive power arises.
