Abstract
An intraocular lens (IOL) injection device is modularized to enable cleaning of internal components after surgery. The device includes first and second housing modules. These modules collectively define a passageway along which an injector rod moves between a retracted position and an extended position. The first module is further configured to accommodate a lens cartridge module. The cartridge module has disposed therein an IOL, in alignment with the passageway. Thus as the rod moves from the retracted position to the extended position, a front portion of the rod that is substantially surrounded by the first module in the retracted position moves into the cartridge module and displaces the IOL. This causes the front portion of the rod to accumulate on it viscoelastic substances. The first module, though, is configured to detach from the second module, to thereby expose the front portion of the rod in the retracted position for cleaning.
