Abstract
The invention relates to a device that permits an intra-ocular lens, which has been elastically deformed, to be injected through a cannula (5) into an eye by means of a ram (6) with a translatory displacement action. The device contains a lens holder (1), which can be inserted into said device. The lens holder contains an elastic base (8), which is deformable in such a way that it can be converted from a relaxed, open position into a tensioned, closed position by bending. During said deformation, the intra-ocular lens that is in contact with the lens holder (1) is subjected to an increased curvature. This permits the careful deformation of the intra-ocular lens and a precise, reliable injection of the latter.
Claims21
1-17. (canceled)
A device for inserting an elastically deformable intra-ocular lens into an eye, comprising:
- a lens holder including an elastic base which is deformable from a relaxed, open position into a stressed, closed position, wherein the deformation of the elastic base increases a curvature of the intra-ocular lens disposed in the lens holder;
- a cannula;
- and
- a moveable plunger, wherein movement of the plunger pushes the elastically deformed intra-ocular lens from the lens holder through the cannula into the eye.
The device according to 19, wherein the elastic base in the stressed position forms a channel in which the curved intra-ocular lens is located.
