Patent ID: 8784485

Claim:
An injector for inserting an intraocular lens into an eye, the injector comprising: a lumen, said lumen comprising a terminal portion at a distal end and a proximal portion juxtaposed with said terminal portion, the terminal portion including an outlet, said lumen further comprising an inner surface; and an injector plunger at least partially disposed within said lumen for generating a driving force on the intraocular lens, the driving force causing the intraocular lens to move within said lumen, the lens moving through said proximal portion before said terminal portion, wherein the injector comprises a lens coefficient of friction between said inner surface and the intraocular lens when the lens is moving through said lumen, said lens coefficient of friction associated with a lens frictional force that resists the driving force; said lens coefficient of friction having a first value when the lens is at a first location within said proximal portion and a second value when the lens is at a second location within said terminal portion, the first value being smaller than the second value, and wherein a portion of the inner surface at the first location is smooth with a lubricious coating disposed thereon and a portion of the inner surface at the second location is free of the lubricious coating.
