An IOL injector plunger having IOL compression arms is described.

Apparatuses, systems, and methods for implanting an intraocular lens into an eye are described. For example, an intraocular lens injector may include a passage formed in a distal end portion of the intraocular lens injector. The passage may define an interior surface, and a ramp may be formed on the interior surface so as to cause a leading haptic of an intraocular lens (IOL) being advanced through the passage to lift above a surface of an optic of the IOL to ensure proper folding of the IOL.

There is provided a toric intraocular lens which improves the visibility of a toric axis. The toric intraocular lens is a toric intraocular lens including a lens body provided with an astigmatic axis. A mark indicating the astigmatic axis is formed at an optical surface of an outer rim portion of the lens body, and a length in a radial direction of the lens body and a length in a circumferential direction of the lens body of external dimensions of the mark are different from each other in top view of the optical surface.

Systems, methods, and devices for inserting an intraocular lens (IOL) into an eye may be provided. An example haptic optic management system may comprise a first cam assembly comprising a first cam body portion, an opening in the first cam body portion, and haptic folder arms disposed in the opening. The haptic optic management system may further comprise a second cam assembly positioned on one side of the first cam assembly, wherein the second cam assembly comprises a second cam body portion, an opening in the second cam body portion, and optic folders disposed in the opening. The haptic optic management system may further comprise a central plate for holding an intraocular lens in the opening of the second cam body portion, wherein the central plate is disposed between the first cam assembly and the second cam assembly.

An intraocular lens insertion device which dramatically reduces the possibility that a plunger damages an intraocular lens, and which can safely and surely insert an intraocular lens into an eye is provided. An intraocular lens insertion unit comprises a lens disposing part for disposing an intraocular lens, a plunger for pushing out the intraocular lens disposed at the lens disposing part, a transition part for deforming the intraocular lens pushed out by the plunger, and a nozzle for ejecting the deformed intraocular lens. The plunger has a lens contact part for contacting the outer edge of the intraocular lens, and a protrusive part for pushing the lens contact part downward the intraocular lens by the deformation of the intraocular lens, both lens contact part and protrusive part are provided at the leading end of the plunger.

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.

The invention relates to an injector assembly comprising a folding chamber which is designed to receive an intraocular lens having a lens body and two haptics, and comprising a holder, a folding wedge which is attached to the holder and is designed to be introduced into the folding chamber in an insertion direction via a folding chamber opening and to thereby fold the intraocular lens, and two sliders which are each designed to shift one of the two haptics onto the lens body via a shifting of the respective slider out of an initial position and into an end position, wherein at least one of the two sliders has a stop which is designed to abut a component attached to the holder in the initial position of the at least one slider, whereby a movement of the component is blocked and the folding wedge is thereby not permitted to fold the intraocular lens, and said stop is designed to permit the movement of the component in the end position of the at least one slider and the folding wedge is thereby permitted to fold the intraocular lens.

The invention relates to an injector assembly having: a folding chamber which is designed to receive an intraocular lens which has an optical body and two haptic elements; a holder; a folding wedge which is attached to the holder and is designed to be introduced into the folding chamber via a folding chamber opening, thereby folding the intraocular lens; and a first slider and a second slider which are each designed to push one of the two haptic elements onto the optical body by means of a displacement of the respective slider from a starting position to an end position, the holder being designed to drive the first slider and/or the second slider from the starting position to the end position by means of a movement of the holder towards the folding chamber.

An embodiment in accordance with the present invention provides an apparatus and method for inserting a lens into pocket in the cornea. The apparatus includes a handle, a plunger extending movably through the lumen of the handle, and a first and a second actuators. In particular the plunger includes a distal segment which extends beyond the distal end of the handle and the first and second actuators are coupled to the plunger configured in such a way to provide different ranges of motion and synchronized movement of a bottom, middle, and top tines of the plunger for improved and safer lens insertion into the corneal pocket.

Systems, methods, and devices for inserting an intraocular lens (IOL) assembly into an eye may be provided. An example optic management system may include a housing having a first end and a second end and a first side extending between the first end the second end. The housing may include a cavity formed in the first side of the housing and configured to accommodate an intraocular lens, wherein the cavity comprises a first end portion, a second end portion, and a central portion. The housing may further include a bore formed in the housing, wherein a first portion of the bore extends from the first end to the cavity. The haptic optic management system may further include a ceiling disposed on the first side of the housing. The haptic optic management system may further include arms pivotably coupled to the housing in the cavity.
