Abstract
An apparatus for implanting an intraocular lens comprises two gripping elements, the front ends of which carry contact elements which are movable towards each other with the gripping elements so that the lens to be implanted can be held therebetween. At least one of the contact elements is mounted rotatably on the respective gripping element.
Claims22
An apparatus for implanting an intraocular lens comprising:
- first and second gripping elements having front ends which are movable towards each other for holding the intraocular lens therebetween for implanting;
- at least one contact element mounted rotatably on each of the gripping elements;
- and
- an abutment disposed adjacent to rearward regions of the contact elements and between the contact elements;
- the thickness of the contact elements being such that the intraocular lens is securely held between the contact elements while the rearward regions of the contact elements bear against side surfaces of the abutment so that rotary movement of the contact elements is prevented.

An apparatus for implanting an intraocular lens comprising:
- first and second gripping elements having front ends which are movable towards each other for holding the intraocular lens therebetween for implanting;
- and
- at least one contact element mounted rotatably on each of the gripping elements;
- the contact elements having increased thicknesses at their rear ends forming contact element regions of enlarged transverse dimensions relative to other regions of the contact elements between which the intraocular lens is held, the contact element regions defining peripheral flat surfaces of enlarged transverse dimensions, said peripheral flat surfaces producing an abutment action when they bear against each other and extending parallel to the axes of the contact elements, said abutment action preventing rotary movement of the contact elements when the intraocular lens is held between the other regions of the contact elements.
