Lens delivery system
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. An apparatus for deploying an intraocular lens, comprising:
a delivery device comprising a fluid therein and a substantially circular lens receiving area, wherein the substantially circular lens receiving area is oriented in a longitudinal direction of the delivery device, wherein the lens receiving area is adapted to hold the intraocular lens in a deformed configuration;
a plunger disposed at a proximal end of the delivery device; and
a distal portion of the delivery device,
wherein the plunger is adapted to be actuated in a distal direction to cause the fluid to flow in a distal direction to force the intraocular lens through the distal portion.
2. The apparatus of claim 1 , wherein the fluid is a lubricious liquid.
3. The apparatus of claim 2 , wherein the fluid is a viscoelastic lubricant.
4. The apparatus of claim 1 , wherein the fluid is contained within a distal region of the delivery device.
5. The apparatus of claim 1 , wherein the distal portion is defined by a tapered inner surface.
6. The apparatus of claim 1 , wherein the intraocular lens comprises an optic portion, a leading haptic, and a trailing haptic.
7. The apparatus of claim 6 , wherein the lens receiving area is shaped to allow the leading haptic to extend distally away from the optic portion while the trailing haptic is not extending proximally from the optic portion.
8. The apparatus of claim 1 , wherein the intraocular lens is an accommodating intraocular lens comprising a flowable media within channels and chambers of the accommodating intraocular lens.
9. A system for deploying an intraocular lens, comprising:
a delivery device comprising a fluid therein and a lens receiving area, wherein the lens receiving area is adapted to hold the intraocular lens in a deformed configuration;
a plunger disposed at a proximal end of the delivery device; and
a tapered portion at a distal end of the delivery device, wherein the lens receiving area is positioned proximal to the tapered portion,
wherein the plunger is adapted to be actuated in a distal direction to cause the fluid to flow in a distal direction to force the intraocular lens through the tapered portion.
10. The system of claim 9 , wherein the lens receiving area is part of a lens chamber.
11. The system of claim 10 , wherein the lens chamber is in fluid communication with a fluid delivery lumen of the delivery device.
12. The system of claim 11 , wherein the lens chamber is shaped to allow a leading haptic of the intraocular lens to extend distally away from an optic portion of the intraocular lens while a trailing haptic is not extending proximally from the optic portion.
13. The system of claim 10 , wherein at least part of the lens chamber is substantially circular-shaped to accommodate a substantially circular optic portion of the intraocular lens.
14. The system of claim 9 , wherein the fluid is a lubricious liquid.
15. The system of claim 14 , wherein the fluid is a viscoelastic lubricant.
16. The system of claim 9 , wherein the fluid is contained within a distal region of the delivery device.
17. The system of claim 9 , wherein the tapered portion is defined by a tapered inner surface.
18. The system of claim 9 , wherein the intraocular lens is an accommodating intraocular lens comprising a flowable media within channels and chambers of the accommodating intraocular lens.
