Patentansprüche
1. Akkomodierfähiges intraokuläres Implantat, das dazu geeignet ist, in einem Kapselsack angeordnet zu werden, umfassend einstückig aus einem elastisch verformbaren Material gebildet eine zentrale optische Linse (1) und zumindest zwei haptische Abschnitte (2, 4) in Form von radial abstehenden Armen, die dazu vorgesehen sind, mit ihren freien Enden an der äquatorialen Zone des Kapselsacks anzuliegen, dadurch gekennzeichnet, daß das freie Ende jedes radialen Arms (2, 4) eine zur Anlage des Implantats an der äquatorialen Zone des Sacks bestimmte Fußplatte (6, 7) hat, deren Außenfläche im wesentlichen torisch ist, wobei die Verbindung zwischen der Fußplatte (6, 7) und dem jeweiligen Arm (2, 4) nach Art eines nahe dem rückwärtigen Rand der Fußplatte (6, 7) gelegenen Scharniers von einem ersten verjüngten Abschnitt (2d, 4d) des Armes gebildet ist, während die Verbindung des Arms mit der Linse nach Art eines Scharniers ist, das im Bereich der Vorderfläche der Linse von einem zweiten ebenfalls verjüngten Abschnitt (2c, 4c) gebildet ist, wobei die Ebene (P 1), welche die ersten verjüngten Abschnitte enthält, hinter der Ebene (P2) liegt, welche die zweiten verjüngten Abschnitte enthält.
2. Implantat nach Anspruch 1, dadurch gekennzeichnet, daß jeder Arm (2, 4) zwischen den scharnierartig verjüngten Abschnitten eine rückseitige Verdickung (2b, 4b) umfaßt.
3. Implantat nach einem der vorhergehenden Ansprüche, dadurch gekenn zeichnet, daß jeder Arm (13, 14) die Form eines Bügels aufweist, dessen Schenkel (13a, 13b, 14a, 14b) über verjüngte Abschnitte, die entlang einer senkrecht zur Mittellinie des Arms verlaufenden Linie (19, 20) ausgerichtet sind, mit der optischen Linse (1) verbunden sind.
4. Implantat nach einem der vorhergehenden Ansprüche, dadurch gekenn zeichnet, daß es ausgehend von der Linse (1) zumindest zwei starre radiale Erweiterungen (10, 12) umfaßt, die zwischen den haptischen Armen angeordnet sind und eine geringere radiale Länge aufweisen als die Arme, um einen Anschlag des Implantats gegenüber den Rändern der Öffnung des Kapselsacks zu bilden.
5. Implantat nach Anspruch 4, dadurch gekennzeichnet, daß die einen Anschlag bildenden Erweiterungen außerhalb von Winkelhalbierenden des Winkels, durch welchen zwei aneinandergrenzende Arme voneinander getrennt sind, angeordnet sind.
6. Implantat nach den Ansprüchen 3 und 4, dadurch gekennzeichnet, daß jede radiale Erweiterung die gemeinsame Zone (15, 16, 17, 18) zum Verbinden zweier nebeneinander angeordneter Schenkel zweier bügeiförmiger Arme mit der Linse bildet.
7. Implantat nach den Ansprüchen 4 und 6, dadurch gekennzeichnet, daß es drei bügeiförmige Arme (21, 22, 23) umfaßt, die in regelmäßigen Abständen um die Linse (1) herum angeordnet sind.

9. Akkomodierfähige Vorrichtung aus Kunstkristall, umfassend ein Implantat (100) nach einem der Ansprüche 1 bis 8, dadurch gekennzeichnet, daß die Vorrichtung ein von dem Implantat getrenntes Element (120, 130) umfaßt, das elastisch verformbar ist und zumindest einen Umfangsbereich hat, der die Form einer radial verformbaren Rinne hat, dessen Durchmesser am Boden der Rinne im Ruhezustand zumindest gleich dem Außendurchmesser des Implantats gemessen an der Außenfläche jeder Fußplatte (110) im Ruhezustand derselben ist.
10. Vorrichtung nach Anspruch 9, dadurch gekennzeichnet, daß der äuquatoriale Durchmesser des separaten Elements (120, 130) gemessen an der Außenseite der Rinne im Ruhezustand dem äquatorialen Durchmesser des Kapselsacks des Patienten entspricht, für den die Vorrichtung vorgesehen ist und der zwischen 20 und 30 Jahre alt ist.
11. Vorrichtung nach Anspruch 9, dadurch gekennzeichnet, daß das oben genannte Element (120) kuppeiförmig ist mit einer rückwärtigen Schale (125), deren Rand eine Rinnenform aufweist.
