Abstract
Apparatuses, systems, and methods for implanting an intraocular lens into an eye are described. For example, an intraocular lens injector may include a passage formed in a distal end portion of the intraocular lens injector. The passage may define an interior surface, and a ramp may be formed on the interior surface so as to cause a leading haptic of an intraocular lens (IOL) being advanced through the passage to lift above a surface of an optic of the IOL to ensure proper folding of the IOL.
Claims20
An intraocular lens (IOL) injector, comprising:
- an injector body, comprising:
- a bore defined by an interior wall, wherein the bore is configured to facilitate intraocular lens advancement through the injector body;
- and
- a plunger slideable within the injector body, the plunger comprising:
- a flange;
- a body portion extending distally from the flange, the body portion having one or more cantilevered members extending from a distal end of the body portion and configured to engage the interior wall of the bore to generate a force resistive to advancement of the plunger through the injector body;
- a plunger rod extending distally from the body portion;
- and
- a plunger tip at a distal end of the plunger rod, the plunger tip configured to push the IOL through the bore.
An intraocular lens (IOL) injector, comprising:
- an injector body, comprising:
- a bore defined by an interior wall, wherein the bore is configured to facilitate intraocular lens advancement through the injector body;
- a longitudinal axis extending centrally along the injector body;
- and
- a plunger slideable within the injector body for pushing the IOL through the bore, the plunger comprising:
- a plunger tip having a first protrusion and a second protrusion extending from the plunger tip,
- wherein the first protrusion and the second protrusion extend parallel relative to the longitudinal axis of the injector body.

- a longitudinal axis extending centrally along the injector body;
- and
- a plunger slideable within the injector body for pushing the IOL through the bore, the plunger comprising:
- a plunger tip having a first protrusion and a second protrusion extending from the plunger tip, wherein:
- the first protrusion extends at an oblique angle relative to the longitudinal axis of the injector body, and
- the second protrusion extends parallel relative to the longitudinal axis of the injector body.
