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.

Abstract: An apparatus for eye surgery may comprise a nozzle having a delivery lumen, an implant bay coupled to the nozzle, an implant disposed in the implant bay, and an actuator coupled to the implant bay. The actuator may comprise a housing; a bore through the housing; a plunger disposed within the bore; and a compression ring. The plunger can be configured to advance within the bore, thereby advancing the implant from the implant bay through the delivery lumen, and the bore can be configured to compress the compression ring as the plunger moves through the bore. In some embodiments, the bore can be configured to increase compression on the compression ring as the first end of the plunger moves through the bore.

Abstract: An apparatus for eye surgery comprising a housing comprising a key track, a bore through the housing, a plunger at least partially disposed in the bore, and a plunger key. The plunger may comprise a rail and a keyway, and the plunger key may comprise a key guide coupled to the key track, an arm coupled to the key guide, and a rail slot through the arm. The arm may be disposed through the keyway of the plunger to allow the arm to move along the key track from a first position to a second position. The arm may be configured to block the rail in the first position and to align the rail slot with the rail in the second position so that the rail can move through the rail slot.
