  • Deformable intraocular lens insertion system
    Patent number: 5807400
    Abstract: A deformable intraocular lens insertion system comprising a lens injecting device and a lens cartridge with a rotary connecting arrangement between the lens injecting device and the lens cartridge. The invention includes preloading the deformable intraocular lens insertion system, in particularly the lens cartridge to reduce the amount of packaging, prevent damage to the deformable intraocular lens during packaging and shipping, allow the preloaded lens cartridge to be autoclaved as a unit, and eliminate the step of loading the lens cartridge with the deformable intraocular lens by the end user to prevent potential damage during this step.
