Disposable intraocular lens insertion system
View Patent ↗An intraocular lens injection system comprising an injecting device and cartridge. The cartridge comprises a lens holding portion and an outer sleeve portion. The invention includes a method of pre-loading the injecting system, particularly the cartridge, to reduce the amount of packaging, prevent damage to the intraocular lens during packaging and shipping, allow the pre-loaded injecting cartridge to be autoclaved as a unit, and eliminate the step of loading the cartridge with the intraocular lens by the end user to prevent potential damage during this step.
1. A system for replacing a cataractuous lens with a comprising:
an injector having a lens receiving portion for receiving and storing a foldable intraocular lens; and
a nozzle portion connected to and extending from the lens receiving portion and having an outer wall and a free end, the lens receiving portion and the nozzle portion having a continuous passageway extending therethrough,
the passageway shaped to reduce an outer dimension of the foldable intraocular lens as it transits through the passageway,
wherein the lens receiving portion includes a transition portion located between the lens receiving portion and the nozzle portion, characterized in that the transition portion has a pair of longitudinal grooves through which the deformable intraocular lens is guided, the grooves remaining in the same horizontal plane; and
a deformable intraocular lens loaded within the lens receiving portion for storage and shipment.
2. The system of claim 1 , wherein the receiving portion is disposed within a removable cartridge configured to be mounted to a barrel.
3. The system of claim 2 , wherein a movable plunger is movably disposed within the barrel.
4. The system of claim 1 , further comprising a cartridge receiver mounted at one end of the barrel for receiving the removable cartridge.
5. The system of claim 4 , wherein at least one of the injecting device and cartridge are made of readily disposable material.
6. The system of claim 4 , wherein at least one of the injecting device and cartridge are made of autoclavable material.
7. The system of claim 1 , wherein said injecting device is made of one or more materials selected from the group consisting of polysulfone, polycarbonate, nylon-66, TEFLON, and KYNAR.
