Lens delivery system
View Patent ↗A lens delivery system having a two folding mechanisms. The first mechanism is structured to fold an intraocular lens stabilizing ring, and the second mechanism is designed to fold an intraocular lens.
1. An intraocular lens and intraocular lens delivery system, comprising:
a multi-component intraocular lens, comprising:
a ring portion;
a lens portion; and
an intraocular lens delivery system, comprising:
a body, the body having a first platform and a second platform;
a first lid coupled to the first platform and configured to cover the first platform;
a second lid coupled to the second platform and configured to cover the second platform, wherein during use the first platform and first lid hold the ring portion detached from the lens portion prior to insertion into an eye and the second lid and second platform hold the lens portion detached from the ring portion prior to insertion into an eye;
a nozzle on a distal end of the body;
a ring pusher coupled with the first platform and configured for reciprocal movement within the first platform such that the ring pusher is configured to compress the ring portion between the first lid and first platform; and
a plunger coupled with the second platform;
wherein the first platform, the second platform, and the nozzle are coupled together and aligned to allow the ring portion and the lens portion to be pushed out of the nozzle in a serial manner.
2. The lens delivery system of claim 1 wherein the ring pusher contains a tab, the tab preventing movement of the plunger.
3. The lens delivery system of claim 1 wherein the plunger further comprises a rod guide.
4. The lens delivery system of claim 3 further comprising a handpiece having a plunger rod and a notch for receiving the body.
5. The lens delivery system of claim 4 wherein the plunger rod extends through the rod guide when the body is installed in the notch and the plunger rod is advanced through the handpiece.
6. The lens delivery system of claim 1 further comprising a handpiece having a notch for receiving the body.
7. The lens delivery system of claim 6 wherein the handpiece further comprises a bumper that causes movement of the plunger when the body is installed within the notch in the handpiece.
8. The lens delivery system of claim 1 , further comprising a removable shipping lock for preventing movement of the ring pusher.
9. The lens delivery system of claim 1 , wherein the alignment of the first platform and second platform is configured to allow the ring portion to be pushed out of the nozzle prior to the lens portion.
10. The lens delivery system of claim 1 , wherein the first platform, second platform, and nozzle are aligned such that during delivery of the intraocular lens the lens portion passes through the second platform before passing through the first platform and passes through the first platform before passing through the nozzle.
11. An intraocular lens and intraocular lens delivery system, comprising:
a multi-component intraocular lens, comprising:
a ring portion;
a lens portion; and
an intraocular lens delivery system, comprising:
a body, the body having a first platform and a second platform;
a first lid coupled to the first platform and configured to cover the first platform;
a second lid coupled to the second platform and configured to cover the second platform, wherein during use the first platform and first lid hold the ring portion separate from the lens portion prior to insertion into an eye and the second lid and second platform hold the lens portion separate from the ring portion prior to insertion into an eye;
a nozzle on a distal end of the body;
a ring pusher having a tab, the ring pusher coupled with the first platform and configured for reciprocal movement within the first platform such that the ring pusher is configured to compress the ring portion between the first lid and first platform prior to insertion;
a plunger having a rod guide coupled with the second platform; and
a removable shipping lock for preventing movement of the ring pusher prior to insertion;
wherein the first platform, the second platform, and the nozzle are coupled together and aligned to allow the ring portion and the lens portion to be pushed out of the nozzle in a serial manner.
12. The lens delivery system of claim 11 further comprising a handpiece having a notch for receiving the body.
13. The lens delivery system of claim 12 wherein the handpiece further comprises a bumper that causes movement of the plunger when the body is installed within the notch in the handpiece.
14. The lens delivery system of claim 11 further comprising a handpiece having a plunger rod and a notch for receiving the body.
15. The lens delivery system of claim 14 wherein plunger rod extends through the rod guide when the body is installed in the notch and the plunger rod is advanced through the handpiece.
16. The lens delivery system of claim 11 wherein the shipping lock has a stop to help prevent movement of the lens portion of the intraocular lens contained within the second platform.
17. The lens delivery system of claim 11 , wherein the alignment of the first platform and second platform is configured to allow the ring portion to be pushed out of the nozzle prior to the lens portion.
18. The lens delivery system of claim 11 , wherein the first platform, second platform, and nozzle are aligned such that during delivery of the intraocular lens the lens portion passes through the second platform before passing through the first platform and passes through the first platform before passing through the nozzle.
