Method and Device for Inserting an Intraocular Lens

摘要

An injector for inserting an intraocular lens into an eye includes a lumen. The lumen can include a terminal portion at a distal end and a proximal portion juxtaposed with the terminal portion. An injector plunger can be disposed within the lumen for generating a driving force on the intraocular lens. The injector can include a lens frictional force that has a first value when the lens is at a first location within the proximal portion and a second value when the lens is at a second location within the terminal portion. The first value can be smaller than the second value. In some embodiments, the lens frictional force increases abruptly from the first value to the second value as the lens approaches the distal end of the lumen.
