Abstract
An apparatus that can be used to fold an intraocular lens or other implant before inserting it into an eye in various locations using variable surgical techniques. Some embodiments may comprise or consist essentially of a haptic folding mechanism configured to fold one or more haptics onto the top of an optic prior to the optic being folded into a nozzle. In some embodiments, a leading haptic lifter or lifting mechanism can be configured to raise and constrain a leading haptic during implant delivery. This leading haptic folding mechanism can actively lift the leading haptic onto the top of the optic.
Claims29
An apparatus for eye surgery, the apparatus comprising:
- an implant bay, the implant bay comprising a base and a cap coupled to the base to form a cavity within the implant bay;
- an implant disposed in the cavity, the implant comprising an optic body, a leading haptic, and a trailing haptic;
- and
- a haptic lifter comprising a lifter arm and a lever arm coupled to the lifter arm;
- wherein the lever arm is configured to rotate the lifter arm in the implant bay toward the cap from a first position to a second position, and the lifter arm is configured to engage the leading haptic between the first position and the second position to lift the leading haptic relative to the optic body.
An apparatus for eye surgery, the apparatus comprising:
- a nozzle;
- an implant bay coupled to the nozzle, the implant bay comprising a base, a cap coupled to the base to form a cavity within the implant bay, and a retention clip;
- an implant disposed in the cavity, the implant comprising an optic body, a leading haptic, and a trailing haptic;
- a haptic lifter comprising a lifter arm, a lever arm, and a pin between the lifter arm and the lever arm, the haptic lifter disposed through the cap so that the lifter arm is at least partially disposed within the cavity, the lever arm is at least partially exposed external to the implant bay, the retention clip engages the pin, the haptic lifter is rotatable about the pin to move the lifter arm toward the cap from a first position to a second position, and the lifter arm is configured to engage the leading haptic between the first position and the second position to lift the leading haptic relative to the optic body;
- and
- an actuator coupled to the base, the actuator configured to advance the implant from the implant bay into the nozzle with the lifter arm in the second position.
An apparatus for managing an intraocular lens having an optic body and a leading haptic coupled to the optic body, the apparatus comprising:
- a base;
- a cap coupled to the base, forming a cavity for holding the intraocular lens;
- a pin;
- a retention clip configured to rotatably couple the pin to the cap;
- a lifter arm coupled to the pin and at least partially disposed through the cap so that the lifter arm is at least partially disposed between the base and the cap;
- and
- a lever arm coupled to the pin and at least partially exposed above the cap, the lever arm configured to move the pin to rotate the lifter arm toward the cap from a first position to a second position;
- wherein the lifter arm is configured to engage the leading haptic between the first position and the second position to lift the leading haptic relative to the optic body.
An apparatus for eye surgery, the apparatus comprising:
- an implant bay;
- an implant disposed in the implant bay, the implant comprising an optic body, a leading haptic, and a trailing haptic;
- a haptic lifter comprising a lifter arm and a lever arm coupled to the lifter arm, the lever arm configured to rotate the lifter arm in the implant bay from a first position to a second position to lift the leading haptic relative to the optic body;
- and
- a plunger configured to advance the optic body under the leading haptic with the lifter arm in the second position.
An apparatus for eye surgery, the apparatus comprising:
- an implant bay;
- an implant disposed in the implant bay, the implant comprising an optic body, a leading haptic, and a trailing haptic;
- a haptic lifter comprising a lifter arm and a lever arm coupled to the lifter arm, the lever arm configured to rotate the lifter arm in the implant bay from a first position to a second position to lift the leading haptic relative to the optic body;
- and
- a plunger having a distal end configured to fold the trailing haptic over the optic body.
