Abstract
Akkommodierbare Intraokularlinse zur Implantation in den Kapselsack eines Auges mit einer Optik (2), welche aufweist einen im Wesentlichen kreisförmigen Rand (5), eine optische Achse (3), eine parallel zur optischen Achse (3) verlaufende Anterior-Richtung (6) und eine diametral entgegengesetzte Posterior-Richtung (9), eine senkrecht zur optischen Achse (3) verlaufende Linsenebene (4), und eine anteriore Außenfläche (7) und eine dieser gegenüberliegend posteriore Außenfläche (8), mit mindestens zwei an der Optik (2) befestigten, einteilig mit der Optik (2) ausgebildeten Haptiken (10; 10a; 10b) zur Abstützung der Optik (2) gegenüber dem Kapselsack, und mit mindestens einer Zellbarriere (27, 30) zur Vermeidung von Zellmigrationen in Richtung auf die optische Achse (3), wobei die Zellbarriere (27, 30) zumindest im Bereich jeder Haptik (10; 10a; 10b) angeordnet ist und von der jeweiligen Haptik (10; 10a; 10b) kammartig in die Posterior-Richtung (9) unter Bildung einer scharfkantigen Kammlinie (28, 31) hervorsteht.Accommodatable intraocular lens for implantation into the capsular bag of an eye with optics (2), which has a substantially circular edge (5), an optical axis (3), an anterior direction (6) parallel to the optical axis (3) a diametrically opposite posterior direction (9), a lens plane (4) extending perpendicularly to the optical axis (3), and an anterior outer surface (7) and an outer posterior surface (8) opposite this, with at least two on the optic (2) attached, with the optics (2) formed haptics (10; 10a; 10b) for supporting the optics (2) relative to the capsular bag, and with at least one cell barrier (27, 30) for preventing cell migration in the direction of the optical axis ( 3), wherein the cell barrier (27, 30) is arranged at least in the region of each haptic (10; 10a; 10b) and of the respective haptic (10; 10a; 10b) in a comb-like manner in the posterior direction (9) to form a sharp-edged one Ridge line (28, 31) protrudes.
Description
Die Erfindung betrifft eine akkommodierbare Intraokularlinse zur Implantation in den Kapselsack eines Auges, insbesondere eines menschlichen Auges.The The invention relates to an accommodatable intraocular lens for implantation in the capsular bag of an eye, especially a human eye.

Intraokularlinsen sind seit langem, insbesondere aus der
Der Erfindung liegt die Aufgabe zugrunde, eine akkommodierbare Intraokularlinse zu schaffen, bei der eine postoperative Zellmigration innerhalb des Kapselsacks weitgehend vermieden wird.Of the Invention is based on the object, an accommodatable intraocular lens in which a postoperative cell migration within the Capsular bag is largely avoided.
Die Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Der Kern der Erfindung besteht darin, zumindest im Bereich jeder Haptik eine posterior vorspringende, scharfkantige Zellbarriere vorzusehen, die sicherstellt, dass eine Migration von Linsenepithelzellen in Richtung auf die optische Achse nicht stattfindet.The The object is solved by the features of claim 1. Of the Core of the invention is, at least in the field of any haptic to provide a posterior protruding, sharp-edged cell barrier, which ensures a migration of lens epithelial cells in Direction to the optical axis does not take place.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous embodiments of the invention will become apparent from the Dependent claims.
