Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung eines Implantats, insbesondere zum Einfuhren in ein Auge und insbesondere zum Einfuhren in den Schlemmschen Kanal eines Auges, bei dem mit einer Laserstrahlung zunächst mindestens eine Region eines Rohlings aus dem Material des Implantats belichtet wird und anschließend die belichtete Region mit einer Flüssigkeit entfernt (geätzt) wird, sodass das Implantat übrig bleibt, wobei der Rohling für die Laserstrahlung durchlässig ist. Darüber hinaus betrifft die Erfindung ein Implantat, welches hohlzylinderförmig und an gegenüberliegenden Seiten der Zylindermantelfläche flüssigkeitsdurchlässig ist sowie eine Anordnung mit einem Implantat, die eine stab-, spiral- oder hülsenförmige mit dem Implantat lösbar verbindbare Einführhilfe aufweist.
