Abstract
A system for preparing an intraocular lens (IOL) injector for receipt of an IOL. A manifold mates with an injector cartridge and easily distributes a lubricating agent to a load chamber of the cartridge. The IOL is then transferred into the load chamber. The cartridge may be rotatably coupled to the handpiece, and then converted from a preparation and load position to a delivery position. The manifold may remain external to the load chamber or fit within the load chamber and include a handle that remains outside. One or more internal channels in the manifold lead from one or more inlet ports to surfaces in the load chamber than contact the IOL.
Claims20
A system for delivering an intraocular lens (IOL) into the eye of a subject, comprising:
- an IOL injector defining an insertion tube and a load chamber for receiving an IOL, the injector further including a pushrod movable through the load chamber for urging the IOL from the load chamber and through the insertion tube in a delivery procedure;
- and
- a fluid manifold formed to mate with the injector and having at least one inlet port that when mated with the injector leads to the load chamber such that a lubricating agent injected into the inlet port is automatically guided onto surfaces within the load chamber that will contact the IOL.
A method for preparing an intraocular lens (IOL) injector for receiving an IOL, comprising:
- providing an IOL injector defining an insertion tube open to a load chamber for receiving an IOL;
- providing a fluid manifold formed to mate with the injector and having at least one inlet port;
- mating the fluid manifold with the cartridge;
- and
- injecting a lubricating agent into the inlet port so that the manifold automatically guides the lubricating agent onto surfaces within the load chamber that will contact the IOL.
