Apparatus for insertion of intraocular lenses into the eye are disclosed. In one embodiment, the apparatus comprises a loading chamber and an injection portion. The loading chamber has a proximal end and a distally extending opening. The loading chamber defines a first lumen and is adapted to receive an intraocular lens in an unfolded state at the distally extending opening and to fold the intraocular lens and maintain the intraocular lens folded as the intraocular lens is placed in the first lumen. The injection portion defines a second lumen aligned with the first lumen and is adapted to receive the folded intraocular lens from the first lumen in the second lumen. The injection portion has an open distal end through which the folded intraocular lens from the second lumen passes to be inserted into an eye.

[ What is claimed is:] [29.]29. An inserter for folding and inserting a flexible intraocular lens through a small incision into the eye comprising:a loading chamber having a generally tubular body providing a first lumen with a proximal end and a distal end adapted to receive an unfolded intraocular lens at said proximal end;said loading chamber having a longitudinal axis and said first lumen having a cross-sectional area at any point on said longitudinal axis measured perpendicular to such axis, said cross-sectional area gradually decreasing from said proximal end to said distal end to effectuate a folding of the intraocular lens as the intraocular lens is passed therethrough;the body of said loading chamber having a distally extending open said proximal end to facilitate the folding of the intraocular lens as the intraocular lens is loaded in said proximal end, said distally extending opening terminating proximally of said distal end, said cross-section area gradually decreasing at a substantially constant rate from the termination of the distally extending opening to said distal end; andan injector portion providing a second lumen contiguous with said first lumen, said second lumen having a length and a cross-sectional area measured perpendicular to said longitudinal axis which gradually decreases at a substantially constant rate distally throughout said length and adapted to allow passage of said folded intraocular lens from said distal end of said first lumen through said second lumen..Iaddend..Iadd.
