Apparatus and methods for loading of an IOL injector
View Patent ↗An IOL injector body including an injector body segment defining a portion of a lumen, and a first loading chamber component coupled to the injector body segments and a second loading chamber component hingedly coupled to the first loading chamber component. The second loading chamber component is capable of rotating about an axis that is parallel to the lumen. An IOL vial including a vial base and an injector guide rotatably mounted in said base, whereby an injector can be inserted along the injector guide and rotated such that a folded IOL can be obtained in the injector. A method of loading an IOL injector with an IOL the method that comprises inserting the IOL injector body into a vial and rotating the IOL injector body relative to the vial to obtain the IOL in the IOL injector body.
1. An IOL injector body and a vial in a combination, the IOL injector body having a lumen with a lumen longitudinal axis, and the IOL injector comprising:
an injector body segment defining a portion of the lumen;
a first loading chamber component coupled to the injector body segment;
a second loading chamber component comprising a lens contact surface, the second loading chamber component being hingedly coupled to the first loading chamber component such that the second loading chamber component is capable of rotating about a second axis that is parallel to the lumen longitudinal axis; and
the vial comprising a vial base and a removable cover, the vial base comprising a cylindrical wall and a bottom surface that define a volume capable of holding a liquid, the cylindrical wall defining a vial central longitudinal axis,
an IOL-holder mount connected to the vial base and disposed in said volume, the IOL-holder mount maintaining an IOL holder having an IOL attached thereto, the IOL-holder mount configured to permit displacement of the IOL-holder towards the bottom surface, and an injector guide rotatably mounted in said volume such that the injector guide can rotate about the vial central longitudinal axis, the injector guide configured to permit the injector body to be inserted into the vial along the injector guide to displace the IOL-holder toward the bottom surface.
2. The injector of claim 1 , wherein the second loading chamber component is configured and arranged such that, upon rotation of the second loading chamber about the second axis, the first loading chamber component and the second loading chamber component combine to form a second portion of the lumen.
3. The IOL injector of claim 2 , the first and second loading chamber components form a rotationally complete portion of the lumen.
4. The injector of claim 1 , wherein the second loading chamber component is configured and arranged to fold an IOL using the lens contact surface upon rotation about the second axis.
5. The injector of claim 4 , wherein the second loading chamber component is configured and arranged to fold the IOL such that after rotation the lens is ready for delivery.
6. The injector of claim 1 , wherein the second axis is aligned with a wall of the injector body.
7. The injector of claim 1 , wherein the first loading chamber component is rigidly connected to the injector body.
8. The injector of claim 1 , wherein the first loading chamber component is integrally formed with the injector body.
9. The injector of claim 1 , wherein the first loading chamber component and the second loading chamber component are configured to form a loading chamber in a closed position.
10. The injector of claim 9 , wherein the first loading chamber component and the second loading chamber component are configured to snap together.
