Ocular implant insertion apparatus and methods
An exemplary ocular implant insertion system includes a case and a preloaded ocular implant insertion apparatus. The apparatus includes first and second movable structures that move the ocular implant in a predetermined sequence. The respective configurations of the case and the ocular implant insertion apparatus are such that the ocular implant insertion apparatus is not removable from the case when the ocular implant insertion apparatus is in the pre-use state and is removable after the first movable structure has moved at least a portion of the optical implant.
1. An ocular implant insertion apparatus, comprising:
a main body configured to store an ocular implant, with an optic and haptics, such that one of the haptics is a proximal haptic and one of the haptics is a distal haptic;
a nozzle associated with the main body; and
a plunger, carried within the main body and movable along a lens advancement axis, including a rod having a proximal portion and a distal portion, the proximal portion of the rod including an operational member, and the distal portion of the rod including a lens contact portion and a recess for the proximal haptic that is above the lens contact portion and that extends proximally from the lens contact portion, the recess having an first lateral side that is open, a second lateral side that is closed by a lateral wall, and an open distal end.
2. An ocular implant insertion apparatus as claimed in claim 1 , wherein
the plunger includes a top wall that extends over at least a portion of the recess.
3. An ocular implant insertion apparatus as claimed in claim 1 , wherein
the plunger includes a slanted wall that defines the proximal end of the recess.
4. An ocular implant insertion apparatus as claimed in claim 3 , wherein
the slanted wall is oriented at a non-perpendicular angle with respect to the lens advancement axis.
5. An ocular implant insertion apparatus as claimed in claim 3 , wherein
the slanted wall extends from the lateral wall to the first lateral side that is open.
6. An ocular implant insertion system as claimed in claim 1 , further comprising:
a slider movable relative to the plunger from a pre-use slider position to a second slider position.
7. An ocular implant insertion apparatus as claimed in claim 6 , wherein
the proximal haptic includes a free end; and
movement of the slider from the pre-use slider position to the second slider position moves the free end of the proximal haptic over the optic.
8. An ocular implant insertion apparatus as claimed in claim 6 , wherein
the distal haptic includes a free end; and
movement of the slider from the pre-use slider position to the second slider position moves the free end of the distal haptic over the optic.
9. An ocular implant insertion apparatus as claimed in claim 1 , wherein
the operational portion comprises a rotatable handle.
10. An ocular implant insertion apparatus as claimed in claim 1 , wherein
the operational portion comprises a thumb rest.
11. An ocular implant insertion apparatus as claimed in claim 1 , wherein
the lens contact portion is planar.
