Abstract

Systems, methods, and devices for inserting an intraocular lens (IOL) assembly into an eye may be provided. A device for delivery of the IOL into the eye may include a nozzle; a bay adjacent to the nozzle, wherein the bay is configured to contain the lens component and comprises a recess in a shape of a haptic extension; and a cam-actuated mechanism comprising a slider configured to move in a direction toward the nozzle; a side arm moveably disposed within the bay, wherein the side arm is positioned at an end of the slider, the end of the slider comprising a groove aligned with the side arm, wherein the groove extends from an outer edge of the slider into an interior portion of the slider, wherein the groove is angled to receive the side arm as the slider moves.

Claims (12)

1. An apparatus for delivery of a lens component into an eye, comprising:

a nozzle;

a bay adjacent to the nozzle, wherein the bay is configured to contain the lens component and comprises a recess in a shape of a haptic extension, wherein the bay comprises an interior wall comprising a slanted surface positioned to contact and fold the lens component;

a cover that is removably attached to the bay; and

a cam-actuated mechanism comprising:

a slider configured to move in a direction toward the nozzle;

a side arm moveably disposed within the bay, wherein the side arm is positioned at an end of the slider, the end of the slider comprising a groove aligned with the side arm, wherein the groove extends from an outer edge of the slider into an interior portion of the slider, wherein the groove is angled to receive the side arm as the slider moves, and wherein the side arm comprises a slanted wall positioned to contact and fold the lens component, wherein the slanted wall of the side arm is positioned opposite to the interior wall of the bay.

2. The apparatus of claim 1 , wherein the bay comprises rails, wherein the side arm is configured to move along the rails as the slider moves toward the nozzle.

3. The apparatus of claim 2 , wherein the slider comprises tracks extending in a direction toward the nozzle.

4. The apparatus of claim 3 , wherein the tracks of the slider extend in a direction that is perpendicular to the rails of the bay.

5. The apparatus of claim 1 , wherein the cover is removably attached to the bay at three stabilization points.

6. The apparatus of claim 5 , wherein the side arm comprises a button, wherein the cover comprises an aperture to receive the button to lock the side arm and prevent movement of the side arm.
