Haptic management for delivery of intraocular implants

An apparatus for eye surgery, the apparatus comprising:

• a delivery lumen;
• an implant chamber;
• an implant disposed in the implant chamber, the implant comprising an optic body, a leading haptic, and a trailing haptic;
• a leading splay arm operable to splay the leading haptic;
• a trailing splay arm operable to splay the trailing haptic;
• a plunger having a first end, a second end, and a bore between the first end and the second end;
• a fluid chamber configured to store a working fluid;
• and
• a push rod;
• wherein the plunger is movable between a first position and a second position to advance the implant from the implant chamber to the delivery lumen, and the push rod is configured to move the working fluid from the fluid chamber through the bore in the second position to advance the implant through the delivery lumen.

A method of ejecting a lens from a surgical delivery system, the method comprising:

• providing the lens in an implant bay;
• straightening a leading haptic of the lens with a leading splay arm;
• advancing the lens from the implant bay to a delivery lumen with a rigid plunger;
• fluidly coupling a fluid chamber to a bore in the rigid plunger through a bypass channel;
• pressing fluid in the fluid chamber to move the fluid through bypass channel and the bore to the delivery lumen;
• and
• advancing the lens through the delivery lumen with the fluid;
• wherein the fluid is a liquid or viscous fluid.
