Lens delivery system
View Patent ↗Delivery devices for delivering an ophthalmic device into an eye. In some embodiments the delivery devices are adapted to deliver an intraocular lens into an eye.
1. A method of loading an intraocular lens, comprising:
providing an intraocular lens with a flowable media therein within a loading chamber and adjacent a delivery device, wherein the loading chamber and the delivery device are in fluid communication, the intraocular lens including an optic portion, a distal haptic, and a proximal haptic; and
positioning the distal haptic such that it extends distally from the optic portion while the proximal haptic is not extending proximally from the optic portion; and
loading the intraocular lens into the delivery device, wherein loading comprises redistributing the flowable media within the intraocular lens.
2. The method of claim 1 wherein loading the intraocular lens into the delivery device comprises compressing an optic portion of the intraocular lens from an unstressed expanded configuration to a stressed delivery configuration.
3. The method of claim 2 wherein compressing the optic portion comprises increasing the length of the intraocular lens.
4. The method of claim 1 wherein the flowable media is a fluid, and wherein the loading step comprises redistributing the fluid within a fluid channel or chamber within the intraocular lens.
5. The method of claim 1 wherein loading the intraocular lens into the delivery device comprises redistributing the flowable media from within the distal haptic to within the optic portion of the intraocular lens.
6. The method of claim 1 wherein positioning an intraocular lens within a loading chamber comprises positioning the intraocular lens within the loading chamber such that an optic portion of the intraocular lens is in a substantially unstressed configuration within the loading chamber.
7. The method of claim 1 wherein the width of the loading chamber is greater than the diameter of an optic portion of the intraocular lens when the optic portion is an unstressed expanded configuration.
8. The method of claim 1 wherein the flowable media channel or chamber is within an optic portion of the lens.
9. A method of loading an intraocular lens into a delivery system, comprising:
an intraocular lens comprising an optic portion in fluid communication with a distal haptic and a trailing haptic, and a flowable media movable between the distal and proximal haptics and the optic portion;
positioning the intraocular lens within a loading chamber such that the distal haptic extends distally from the optic portion while the proximal haptic is not extending proximally from the optic portion; and
loading the intraocular lens from the loading chamber into the delivery device, wherein loading the intraocular lens comprises redistributing the flowable media from within the optic portion to within the distal haptic.
10. The method of claim 9 wherein loading the intraocular lens comprises flowing a fluid into the loading chamber.
11. The method of claim 10 wherein loading the intraocular lens comprises flowing a fluid from the loading chamber into the delivery device.
12. The method of claim 9 wherein the positioning step comprises positioning the optic portion in the loading chamber in a substantially undeformed configuration.
