    摘要： Systems, methods, and devices for inserting an intraocular lens (IOL) assembly into an eye may be provided. An apparatus for delivery of a lens component into an eye may include a housing. The apparatus may further include a plunger at least partially disposed in the housing, wherein the housing comprises an elongated portion and a viscoelastic soft tip at a distal end of the elongated portion, wherein the viscoelastic soft tip has a storage modulus of about 1 megapascal (MPa) to about 300 MPa and a loss module of about 1 MPa to about 300 MPa. The apparatus may further include a drive mechanism operatively coupled to plunger and configured to cause the plunger to translate in the housing. The apparatus may further include a nozzle operatively coupled to the housing through which the plunger delivers the lens component into the eye.

    摘要： Systems, methods, and apparatuses for storing and/or shipping an intraocular lens (IOL) cartridge are provided. A system comprises the IOL cartridge. The IOL cartridge comprises a nozzle and a compartment comprising an IOL. The nozzle is in fluid communication with the compartment. The IOL cartridge further comprises a dial disposed adjacent to the compartment, wherein an inner surface of the dial is exposed to the compartment. The dial is configured to fold the IOL upon rotation of the dial. The IOL cartridge further comprises a plunger case in fluid communication with the compartment, wherein a plunger is movably disposed within the plunger case. The IOL cartridge is configured to removably attach to a handpiece. The system further comprises a packaging comprising a base, wherein the IOL cartridge is disposed within the base; a first removable cover configured to cover a first portion of the IOL cartridge; and a second removable cover configured to cover a second portion of the IOL cartridge, wherein the second removable cover is locked in place by the dial when the dial is in a non-rotated position.

    摘要： Systems, methods, and apparatuses for removably attaching a drive mechanism handpiece to an intraocular lens (IOL) cartridge that folds the IOL upon retraction of a cap, are provided. The IOL cartridge comprises a nozzle and a compartment configured to receive an IOL. The nozzle is in fluid communication with the compartment. The IOL cartridge also includes a retractable cap that covers the nozzle and the compartment. The retractable cap is configured to expose the nozzle and fold the IOL upon retraction of the retractable cap. The IOL cartridge may also include a plunger case that is in fluid communication with the compartment, wherein a plunger is movably disposed within the plunger case.

    摘要： This intraocular lens (IOL) injector cartridge has a proximal opening in a main body for receiving an IOL. The main body has a lumen that extends longitudinally to a distal end having an opening smaller than the IOL. Passage through the lumen compresses or rolls the IOL so that when the distal end is inserted through a small incision in the eye the IOL can be expelled into the capsular bag. The distal end of the cartridge is beveled with a leading tip in front of a trailing heel. The characteristics of the beveled end are such that damage to the IOL is reduced. The bevel may be straight or curved and includes a distal face defined by the thickness of the distal end between the lumen and an exterior surface. The distal face may be flush with the bevel or chamfered. An inner corner angle between the distal face and the lumen is ≥60° to reduce the chance of scratching the IOL as it passes out of the distal opening.
