Abstract: An apparatus for folding 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 elevate and constrain a leading haptic during implant delivery. This leading haptic folding mechanism can passively lift the leading haptic onto the top of the optic.

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.

Abstract: Various systems and techniques for inserting an intraocular lens are disclosed. In particular implementations, a system and a technique for inserting an intraocular lens may include the ability to move, in response to a force being applied in a first direction along a longitudinal axis, a first plunger tip along the longitudinal axis and into a delivery cartridge to fold an intraocular lens and move in a second direction along the longitudinal axis in response to the applied force being reduced. The system and the technique may also include the ability to engage a second plunger tip and move, in response to a force being applied in the first direction along the longitudinal axis, the second plunger tip along the longitudinal axis and into the delivery cartridge to insert the intraocular lens.
