Preloaded IOL injector
View Patent ↗A preloaded intraocular lens injection device includes a retainer for releasably holding an IOL in an unstressed state. The retainer and IOL are removably attached to an injector body and are sealed in the same package for delivery to a surgeon. In an alternate embodiment, the retainer and IOL are coupled together and sealed in one package and the injector body is sealed in a separate package with the surgeon attaching the retainer to the injector body at the time of surgery. To deliver the IOL through the injector body, the retainer is removed from the injector body causing the IOL to release from the retainer and become located in an unstressed state in the injector body. A compressor is moved to the closed position to compress the IOL, the injector tip is inserted through a small incision in an eye and a plunger is advanced to push the IOL through and out the injector body tip and into an eye.
1. An injector device comprising:
an injector body having a lumen extending longitudinally therethrough;
an opening providing access to the lumen of said injector body;
a retainer releasably holding an IOL comprising an optic, said retainer adapted to be removably attached to the injector body proximate said opening;
a movable compressor drawer coupled to the injector body proximate the opening, the compressor drawer having an optic stripper element attached thereto,
the optic stripper element adapted to extend between the retainer and the optic when the retainer is removably attached to the injector body wherein, when the retainer is removably attached to the injector body and the compressor drawer is in a partly closed position, the optic stripper element extends between the retainer and the optic, and when the retainer is removably attached to the injector body and the compressor drawer is in a fully open position, the optic stripper element does not extend between the retainer and the optic.
2. The injector device of claim 1 , wherein said compressor drawer is moveable from a fully open position to a partly closed position and subsequently to a fully closed position with respect to said injector body.
3. The injector device of claim 2 , wherein the compressor drawer further comprises a vertical flange, said flange abutting said retainer when said retainer is remobably attached to said injector body and when said compressor drawer is moved to said partly closed position, thereby preventing said compressor drawer from moving to said fully closed position until said retainer is removed from said injector device.
4. The injector device of claim 3 wherein said optic stripper element is configured such that upon removal of said retainer from said injector device, said IOL becomes located in said lumen of said injector device and is prevented from releasing with said retainer.
5. The injector device of claim 4 wherein said optic stripper element includes at least one through hole configured to engage the periphery of said IOL during removal of said retainer from said injector body.
6. The injector device of claim 2 , wherein the compressor drawer is coupled to the injector body during each of the fully open position, the partly closed position and the fully closed positions.
7. The injector device of claim 1 , wherein the IOL further comprises a first haptic and a second haptic, and wherein the compressor drawer further comprises a first and second haptic stripper elements that extend on either side of said optic stripper element, the first and second haptic stripper elements adapted to extend between the retainer and the first haptic of the IOL, and between the retainer and the second haptic of the IOL, respectively, when the retainer is removably attached to the injector body.
8. The injector device of claim 1 further comprising a finger grasp flange attached to said injector body opposite said compressor drawer to assist in manually handling said device.
9. The injector device of claim 1 , wherein, when the optic stripper element is extended between the retainer and the optic and when the retainer is detached from the injector body, the IOL is detached from the retainer.
10. The injector device of claim 1 , wherein the IOL has an optical axis and the compressor drawer is adapted to slide in a direction substantially perpendicular to the optical axis.
11. The injector device of claim 1 , wherein the compressor drawer and the retainer are independently coupled to the injector body, such that the retainer can be detached from the injector without detaching the compressor drawer from the injector body.
12. The injector device of claim 2 wherein, when the retainer is removably attached to the injector body and the compressor drawer is in the partly closed position, the optic stripper element extends between the retainer and the optic, and when the retainer is removably attached to the injector body and the compressor drawer is in the fully open position, the optic stripper element does not extend between the retainer and the optic.
13. The injector device of claim 1 , wherein the retainer is removably attached to the injector body.
14. The injector device of claim 13 wherein, when the compressor drawer is in the partly closed position, the optic stripper element extends between the retainer and the optic, and when the compressor drawer is in the fully open position, the optic stripper element does not extend between the retainer and the optic.
15. The injector device of claim 1 , wherein said compressor drawer includes a spring arm having an edge configured to abut a feature of said injector device when said compressor drawer is in a partly closed position to prevent further closing of said compressor drawer until said edge is released from said feature of said injector device.
