Abstract:
1. A device, comprising: an intraocular lens having an optical part, an outer edge adjacent to the optical part, and a haptic adjacent to the outer edge; a lens disposing part configured to hold the intraocular lens; a plunger, including a distal portion defining a size and having a lens contact part and a protrusive part, which pushes the intraocular lens along a lens travelling axis, the lens contact part defining a lens contact surface that has a first end and a second end that is closer to the protrusive part than the first end, and the protrusive part defining a distal end that is located distally of the lens contact surface, a first surface on one side of the distal end and a second surface on the opposite side of the distal end, the second surface being closer to the lens contact surface than the first surface; a nozzle through which the intraocular lens is ejected; and a transition part between the lens disposing part and the nozzle, the transition part having an inner surface defining a lumen that decreases in size towards the nozzle; wherein the respective sizes of the intraocular lens, the plunger distal portion and the transition part lumen are such that, when the lens contact part engages the optical part and pushes the intraocular lens through the transition part there will be a gap, between the second surface of the plunger protrusive part and the optical part, that extends from the distal end of the protrusive part to the lens contact part.
