Abstract

Intraocular lens delivery devices and methods of use.

First claim

What is claimed is:

1. A method of delivering an intraocular lens, comprising:
providing a cartridge comprising an optic portion receiving area, a leading haptic receiving area, and a trailing haptic receiving area, wherein the intraocular lens is housed within the cartridge;
coupling the cartridge to a delivery device through a port defined along the delivery device, wherein part of the delivery device is proximal to the port and another part of the delivery device is distal to the port;
activating a first actuator to cause a leading haptic of the intraocular lens to move from the leading haptic receiving area and to cause a trailing haptic of the intraocular lens to move from the trailing haptic receiving area, wherein activating the first actuator also causes the intraocular lens to move out of the cartridge; and
activating a second actuator to cause the intraocular lens to advance out of the delivery device.

2. The method of claim 1 , wherein the trailing haptic receiving area of the cartridge extends laterally away from an axis passing through the optic portion receiving area.

3. The method of claim 1 , wherein when the trailing haptic of the intraocular lens is positioned in the trailing haptic receiving area, a segment of the trailing haptic curves circumferentially around the optic portion of the intraocular lens.

4. The method of claim 1 , wherein a terminal end of the leading haptic points away from an optic portion of the intraocular lens when the intraocular lens is moved out of the cartridge into a nozzle.

5. The method of claim 4 , wherein activating the first actuator further comprises first retracting the first actuator and then advancing the first actuator in a direction of the nozzle.

6. The method of claim 5 , wherein advancing the first actuator further comprises advancing the first actuator using a trigger.

7. The method of claim 1 , wherein activating the first actuator further causes the trailing haptic of the intraocular lens to be deformed to a straightened configuration as the trailing haptic moves from the trailing haptic receiving area.

8. The method of claim 1 , wherein the cartridge comprises a first portion and a second portion connected by a hinge-type connection.

9. The method of claim 8 , wherein the cartridge is molded with the optic portion receiving area formed within at least one of the first portion and the second portion.

10. A method of delivering an intraocular lens, comprising:
providing a detachable cartridge comprising an optic portion receiving area, a leading haptic receiving area, and a trailing haptic receiving area, wherein the intraocular lens is housed within the cartridge;
coupling the cartridge to a delivery device, wherein the delivery device comprises a port for receiving the cartridge;
activating a first actuator to cause a leading haptic of the intraocular lens to move from the leading haptic receiving area and to cause a trailing haptic of the intraocular lens to move from the trailing haptic receiving area, wherein activating the first actuator also causes the intraocular lens to move out of the cartridge;
activating a second actuator to cause the intraocular lens to advance out of the delivery device; and
separating the cartridge from the delivery device subsequent to causing the intraocular lens to advance out of the delivery device.

11. A method of delivering an intraocular lens, comprising:
coupling a cartridge housing the intraocular lens to a delivery device, wherein the cartridge comprises an optic portion receiving area, a leading haptic receiving area, and a trailing haptic receiving area; and
activating a first actuator to cause a leading haptic of the intraocular lens to move from the leading haptic receiving area and to advance the intraocular lens distally out of the cartridge into a nozzle, wherein advancing the intraocular lens distally comprises advancing a fluid through the cartridge in response to activating the first actuator, and wherein advancing the fluid through the cartridge causes a trailing haptic of the intraocular lens to be deformed, wherein the first actuator is positioned distally of a second actuator when the first actuator and the second actuator are both coupled to the delivery device.

12. The method of claim 11 , wherein a terminal end of the leading haptic points away from an optic portion of the intraocular lens when the intraocular lens is moved out of the cartridge into the nozzle.

13. The method of claim 11 , wherein the trailing haptic of the intraocular lens is deformed to a straightened configuration as the trailing haptic moves from the trailing haptic receiving area.

14. The method of claim 11 , further comprising activating the second actuator to cause the intraocular lens to advance out of the nozzle, wherein the second actuator is a plunger.
