摘要：
The present application relates to an IOL insertion device that facilitates the injection of the IOL in a controlled manner. The insertion device includes a front modular portion (202) and an injector (102). The modular portion may be preloaded with an IOL and coupled with the injector. The injector includes a distal portion, a body, and a plunger. The distal portion includes a front seal (116) which has a longitudinal bore (118) at the center, through which a distal portion of the plunger passes. The plunger tip is tapered. The plunger also includes a sealing element situated between its distal portion and its proximal portion. The sealing element includes a small aperture through which a fluid, such as a viscoelastic or a balanced salt solution ("BSS") and the like, may pass toward the proximal end of the body when the plunger advances distally. As the fluid passes through the small aperture on the sealing element on the plunger, a constant speed and force is maintained as the IOL is ejected into the eye.
