Title
(EN) DEVICE FOR INSERTING A FLEXIBLE INTRAOCULAR LENS
(FR) DISPOSITIF POUR L'INSERTION D'UNE LENTILLE INTRAOCULAIRE SOUPLE
Abstract
(EN)
This invention is a device for inserting a flexible intraocular lens (12) into an eye comprising a tubular member (16) and a plunger (18). The tubular member includes a staging area (45), a lumen, and an open distal end (95). The staging area supports the lens in an unstressed state prior to engagement by the plunger. In the unstressed state, the optic (48) of the lens is suspended in a pocket to avoid any substantial contact with interior portions of the tubular member. The plunger includes a slot (132) in its distal tip fo receiving and gripping the lens. With this construction, the lens can be inserted into the eye in one continuous motion. Further, the plunger holds the lens when the lens is moved out of the tubular member.
(FR)
La présente invention a pour objet un dispositif formé d'un élément tubulaire (16) et d'un plongeur (18) et destiné à l'insertion d'une lentille intraoculaire souple (12) dans un ÷il. L'élément tubulaire comprend une zone en gradins (45), une lumière et une extrémité distale ouverte (95). La zone en gradins porte la lentille sans contraintes avant l'action du plongeur. En l'absence de contraintes, l'optique (48) de la lentille est suspendue dans une poche afin d'éviter tout contact important avec les parties intérieures de l'élément tubulaire. Le plongeur comprend une fente (132) dans sa pointe distale, qui reçoit et maintient la lentille. Cette construction permet d'introduire la lentille dans l'÷il en un seul mouvement continu. Le plongeur maintient en outre la lentille lorsque celle-ci sort de l'élément tubulaire.
