Abstract
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.
Claims21
An intraocular lens insertion system for inserting an intraocular lens into the eye, comprising:
- an injecting device having a cartridge receiver;
- and
- a cartridge for accommodating the intraocular lens, said cartridge including a lens holding portion and a sleeve portion that can be connected together after inserting the intraocular lens into said lens holding portion of said cartridge to form an assembled cartridge.
A method of implanting an intraocular lens, comprising the steps of:
- loading an intraocular lens into a cartridge having a partially open passageway and a downwardly tapering cross-sectional sized passageway portion;
- covering the open passageway portion;
- loading said cartridge into an injecting device;
- and
- forcing the intraocular lens through the downwardly tapering cross-sectional sized passageway of said cartridge to further reduce the outer dimensions of the intraocular lens to enable a reduction is the size of an incision in the eye.
A method of implanting an intraocular lens, comprising the steps of:
- pre-loading an intraocular lens into an intraocular lens injecting system;
- and
- packaging said intraocular lens injecting system with said pre-loaded intraocular lens.
