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.
Claims11
An intraocular lens insertion system, the system comprising:
- a lens chamber adapted to receive an intraocular lens;
- a delivery cartridge coupled to the lens chamber;
- a plunger adapted to be manipulated by a user and moved along a longitudinal axis;
- and
- a plunger tip chamber, the plunger tip chamber comprising:
- a first plunger tip adapted to move from a first position to a second position to engage the intraocular lens and advance the intraocular lens from the lens chamber into the delivery cartridge;
- and
- a second plunger tip adapted to engage the intraocular lens in the delivery cartridge and to eject the intraocular lens from the delivery cartridge;
- and
- a spring adapted to compress when the plunger moves the first plunger tip from the first position to the second position and adapted to retract the first plunger tip to the first position.
