Rotatable IOL insertion apparatus and method for using same
First Claim
1. An apparatus for inserting a folded intraocular lens through an incision into an eye comprising:
- a tube defining a hollow passage, the tube having an ejection port through which the intraocular lens is passed from the hollow passage into an eye;
an injector rod longitudinally movable within the hollow passage of the tube, the injector rod having a distal segment adapted to urge the folded intraocular lens distally through the hollow passage;
a housing including a distal portion adapted to hold the tube, and a proximal portion coupled to the distal portion; and
a rotation assembly located relative to the distal portion so that the distal portion is axially rotated relative to the proximal portion as the injector rod is moved distally through the tube.

Abstract
An apparatus for inserting a folded intraocular lens through an incision into an eye comprising a tube defining a hollow passage, the tube having an ejection port through which said intraocular lens is passed from the hollow passage into an eye, an injector rod longitudinally movable within the hollow passage of the tube, the injector rod having a distal segment adapted to contact the folded intraocular lens within the hollow passage of the tube to urge the folded intraocular lens distally through the hollow passage, a housing including a distal portion adapted to hold the tube, and a proximal portion coupled to the distal portion, and a rotation assembly located relative to the distal portion so that the distal portion is axially rotated relative to the proximal portion as the injector rod is moved distally through the tube.

11. An apparatus for inserting a folded intraocular lens through an incision into an eye comprising:
-
a tube defining a hollow passage, the tube having an ejection port through which the intraocular lens is passed from the hollow passage into an eye;
an injector rod longitudinally movable within the hollow passage, the injector rod having a distal end portion structured to urge the folded intraocular lens distally through the hollow passage of the tube;
a housing including a distal portion adapted to hold the tube, and a proximal portion coupled to the distal portion; and
a cam race disposed on the injector rod and a cam follower disposed on the distal portion, the cam race and the cam follower being positioned so that the distal portion is axially rotated relative to the proximal portion a controlled amount as the injector rod is moved distally through the tube. - View Dependent Claims (12, 13, 16, 19)

14. A method for inserting an intraocular lens into an eye comprising:
-
placing an intraocular lens in a folded condition in an insertion apparatus comprising a tube defining a hollow passage having an ejection port through which the intraocular lens is ejected from the hollow space, an injector rod longitudinally movable within the hollow passage of the tube, the injector rod having a distal end portion adapted to urge the folded intraocular lens distally through the hollow passage, a housing including a distal portion adapted to hold the tube, and a proximal portion coupled to the distal portion and a rotation assembly located relative to the injector rod so that the distal portion is axially rotated relative to the proximal portion as the injector rod is moved distally through the tube;
positioning the ejection port in proximity to or through an incision in said eye; and
moving the injector rod distally. - View Dependent Claims (15, 17, 18, 20)
