INTRAOCULAR LENS INSERTER CARTRIDGE WITH A TRAILING HAPTIC PROTECTION STRUCTURE
20220079807 · 2022-03-17 ·

A cartridge of an intraocular lens (IOL) inserter includes an insertion nozzle, having a distal insertion channel; an IOL-folding stage, having a proximal insertion channel; and a haptic protection structure to protect a trailing haptic of the IOL from damage by a push-rod of the inserter. The haptic protection structure includes a proximal guiding groove in the IOL-folding stage, or a distal guiding groove in the insertion nozzle. The haptic protection structure further includes a trailing-haptic notch, to guide a trailing haptic protruding from the proximal guiding groove; and a trailing-haptic retainer, to secure the trailing haptic out of the proximal insertion channel. An intraocular lens inserter includes an inserter cylinder; a push-rod in the inserter cylinder; a cartridge-receiving insertion tip, to receive a cartridge that includes an insertion nozzle, having a distal insertion channel; an intra-ocular lens-folding stage, having a proximal insertion channel; and a haptic protection structure.

Injector assembly for inserting an intraocular lens and injector

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.

Retractable cap actuation for an intraocular lens cartridge

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.

Hydraulic delivery of surgical implants

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 plunger disposed within the housing, a bore through the plunger, a first coupling proximate to a first end of the plunger, and a second coupling integral to the housing. The bore may be fluidly coupled to the implant bay. The first coupling may be configured to receive a hydraulic driver and fluidly couple a working fluid in the hydraulic driver to the bore. A portion of the plunger may be slidingly disposed through the second coupling. In some embodiments, the second coupling may be configured to retain a drive coupling of the hydraulic driver in a fixed position relative to the housing.
