Abstract
A lens case for an intraocular lens having a deformable optic, including a folder for receiving the intraocular lens and folding the deformable optic about a fold axis. A retainer adjacent the folder holds the intraocular lens against substantial pivotal movement relative to the retainer about a pivot axis which is generally transverse to the fold axis. The folder and retainer are relatively pivotable about the pivot axis so that the orientation of the fold axis relative to the retainer and the deformable optic can be changed.
Claims19
A lens case for an intraocular lens having a deformable optic, said lens case comprising:
- a folder for receiving the intraocular lens and folding the deformable optic about a fold axis;
- a retainer adjacent the folder for holding the intraocular lens against substantial pivotal movement relative to the retainer about a pivot axis which is generally transverse to the fold axis;
- the folder including jaws for loosely receiving and supporting the intraocular lens so as to allow relative pivotal movement of the folder and the intraocular lens about said pivot axis, and said jaws are relatively movable to fold the deformable optic about the fold axis;
- and
- the folder and retainer being mounted for relatively pivotal movement about said pivot axis whereby the orientation of the fold axis relative to the retainer can be changed.

A lens case for an intraocular lens having a deformable optic, said lens case comprising:
- a folder for receiving the intraocular lens and including jaws which are relatively movable to fold the deformable optic about a fold axis;
- a base, the folder being mounted on the base for pivotal movement relative to the base about a pivot axis which is generally transverse to the fold axis;
- and
- the base including a retainer for holding the intraocular lens against substantial pivotal movement about said pivot axis relative to the retainer whereby the orientation of the fold axis relative to the folder can be changed by relatively pivoting the folder and base.

An IOL package comprising:
- an intraocular lens having a deformable optic with an optical axis;
- a folder for receiving the intraocular lens and folding the deformable optic about a fold axis which is generally transverse to the optical axis;
- a retainer, said folder being on the retainer and being removable from the retainer, the retainer and the folder being mounted for relative pivotal movement generally about the optical axis while the folder is on the retainer;
- the retainer holding the intraocular lens against substantial pivotal movement relative to the retainer generally about the optical axis so that the orientation of the fold axis relative to the retainer can be changed;
- and
- said folder being capable of supporting and folding the deformable optic about the fold axis when the folder is removed from the retainer.

A method of folding an intraocular lens having a foldable optic with an optical axis along any of a plurality of fold axes, said method comprising:
- supporting the intraocular lens on an IOL folder in a first angular position about a pivot axis so that the IOL folder can fold the foldable optic about a first fold axis;
- retaining the intraocular lens against substantial pivotal movement about the pivot axis;
- pivoting the IOL folder relative to the intraocular lens about the pivot axis to a second angular position so that the IOL folder can fold the foldable optic about a second fold axis;
- folding the foldable optic about the second fold axis using the IOL folder;
- and
- removing the intraocular lens from the IOL folder with the foldable optic folded about the second fold axis.

- a folder for receiving the intraocular lens and folding the deformable optic about a fold axis;
- a retainer adjacent the folder for holding the intraocular lens against substantial pivotal movement relative to the retainer about a pivot axis which is generally transverse to the fold axis;
- the folder and retainer being mounted for relative pivotal movement about said pivot axis whereby the orientation of the fold axis relative to the retainer can be changed;
- and
- the retainer having a fixation member receiving section for receiving a fixation member of the intraocular lens and holding the fixation member to thereby hold the intraocular lens against substantial pivotal movement relative to the retainer about said pivot axis and the folder having jaws for receiving and supporting the deformable optic at a location radially inwardly of the fixation member receiving section.
