More Information
Summary:An IOL insertion apparatus including a cartridge with an IOL-receiving chamber, a handpiece into which the cartridge is loaded, and a plunger rod that extends through a lumen in the cartridge to reliably engage the IOL therein. The chamber has a recess in one wall that creates a space adjacent the proximal edge of the IOL positioned therein. A lip or projection on the plunger rod is aligned with the space to extend underneath the proximal edge of the IOL. The plunger rod may define a forked end with a groove into which the proximal edge of the IOL is captured. The cartridge may be of the type that folds the IOL therein. The recess may continue the entire length of the cartridge to guide the plunger rod therethrough. The cartridge lumen may converge so that the IOL is further compressed therealong. An inwardly-directed wall portion in the cartridge may help guide the lip of the plunger rod into the recess.
