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.

Method and device for inserting an intraocular lens

Method for inserting an intraocular lens

Disclosed are apparatus for delivering an accommodating intraocular lens to an eye. One apparatus includes an injector with a longitudinal injection passage that has a longitudinal injection axis. The apparatus also includes an accommodating intraocular lens having two interconnected viewing elements. The injector has a member for moving the lens into the injection passage of the apparatus. The accommodating intraocular lens has a longitudinal bisection axis and is initially disposed within the injector with the longitudinal bisection axis at an angle which is non-parallel and non-perpendicular to the injection axis. Additional apparatus and methods are disclosed as well.
