Abstract

La présente invention concerne un kit permettant de réaliser l'insertion d'un outil d'insertion de lentille intraoculaire, à l'aide duquel il est possible d'expérimenter virtuellement et de manière répétée le fonctionnement d'un outil d'insertion de lentille intraoculaire pour l'insertion dans un globe oculaire. Le kit permettant de réaliser l'insertion d'un outil d'insertion de lentille intraoculaire comporte un trou d'insertion dans lequel est insérée la pointe de l'outil d'insertion de lentille intraoculaire et une partie de pression permettant d'appuyer sur la surface latérale de la pointe de l'outil d'insertion de lentille intraoculaire inséré dans le trou d'insertion, la partie de pression étant conçue de sorte à avoir un élément élastique qui occupe au moins une partie du trou d'insertion quand le trou d'insertion pour l'outil d'insertion de lentille intraoculaire est vu depuis la direction normale à une surface d'ouverture du trou d'insertion.
