Abstract
Various systems and techniques for inserting an intraocular lens are disclosed. In particular implementations, a system and a technique for inserting an intraocular lens may include the ability to move, in response to a force being applied in a first direction along a longitudinal axis, a first plunger tip along the longitudinal axis and into a delivery cartridge to fold an intraocular lens and move in a second direction along the longitudinal axis in response to the applied force being reduced. The system and the technique may also include the ability to engage a second plunger tip and move, in response to a force being applied in the first direction along the longitudinal axis, the second plunger tip along the longitudinal axis and into the delivery cartridge to insert the intraocular lens.
Claims13
An intraocular lens insertion system, the system comprising:
- a lens chamber adapted to receive an intraocular lens;
- a plunger adapted to be manipulated by a user;
- and
- a plunger tip chamber, the plunger tip chamber comprising:
- a first plunger tip adapted to directly engage the intraocular lens and advance the intraocular lens from the lens chamber along a first longitudinal span of the lens insertion system to facilitate folding of the intraocular lens;
- and
- a second plunger tip adapted to directly engage the intraocular lens, after being folded, to eject the intraocular lens, the second plunger tip being made of a softer material than the first plunger tip.
