Ophthalmo-surgical injector
An ophthalmo-surgical injector includes an injector body, a tip with which an intraocular lens can be pressed out of the injector, a first plunger mounted longitudinally displaceably on the injector body and having a first projection, a shaft rotatably mounted in the injector body and having a first guide and a second guide which are each wound about the shaft, and a second plunger mounted longitudinally displaceably on the injector body and having a second projection. The first projection engages in the first guide, such that the first plunger is configured to effect, with a longitudinal displacement of the first plunger, a rotation of the shaft about a longitudinal axis of the injector body, and the second projection engages in the second guide, as a result of which the shaft is configured to effect, with the rotation effected by the first plunger, a longitudinal displacement of the second plunger.
Intraocular lens insertion device
There is provided an intraocular lens insertion device capable of appropriately regulating the motion of a rear supporting portion during a process of moving an intraocular lens, and reducing the possibility of reoperation being required after the intraocular lens is inserted into an eye. An intraocular lens insertion device 1 comprises a main body 2, and a slider 3 and a plunger 4 that are attached to the main body 2. Further, the intraocular lens insertion device 1 is of a preset type in which an intraocular lens 5 is placed inside the main body 2 in advance. The slider 3 includes a first abutting portion 21 for pushing up a supporting portion 7 (rear supporting portion 7a) arranged on a rear side of an optical part 6 with respect to a lens advancement axis A, and second abutting portions 22a, 22b abutting against an outer edge of a rear portion of the optical part 6.
INTRAOCULAR LENS INSERTION DEVICE
Accordingly, embodiments of the present invention provide an IOL insertion device that facilitates the injection of the IOL in a controlled manner The insertion device includes a front modular portion and an injector. The modular portion may be preloaded with an IOL and coupled with the injector. The injector includes a distal portion, a body, and a plunger. The distal portion includes a front seal which has a longitudinal bore at the center, through which a distal portion of the plunger passes. The plunger tip is tapered. The plunger also includes a sealing element situated between its distal portion and its proximal portion. The sealing element includes a small aperture through which a fluid, such as a viscoelastic or a balanced salt solution (BSS) and the like, may pass toward the proximal end of the body when the plunger advances distally. As the fluid passes through the small aperture on the sealing element on the plunger, a constant speed and force is maintained as the IOL is ejected into the eye.
INTRAOCULAR LENS INSERTER
Intraocular lens inserters and methods of use are disclosed. An example intraocular lens inserter may include an interior assembly having a movable member disposed therein. The movable member is movable in response to a pressure of a compressed gas. In response to the pressure of the compressed gas, the moveable member pressurizes a substantially incompressible fluid. The pressurized substantially incompressible fluid is used to advance a plunger. The plunger advances an intraocular lens through a lumen for insertion into an eye.
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.
Ocular implant insertion apparatus and methods
An exemplary ocular implant insertion system includes a case and a preloaded ocular implant insertion apparatus. The apparatus includes first and second movable structures that move the ocular implant in a predetermined sequence. The respective configurations of the case and the ocular implant insertion apparatus are such that the ocular implant insertion apparatus is not removable from the case when the ocular implant insertion apparatus is in the pre-use state and is removable after the first movable structure has moved at least a portion of the optical implant.

Inserter cap and related features
A cap configured and dimensioned to sweep or fold one or more haptics when removed from an insertion device. The cap may further have a pin, one or more snaps and/or one or more locks. The cap may also have one or more ports and/or one or more windows. An insertion system having a handpiece, a cartridge, and a cap configured and dimensioned to sweep or fold one or more haptics when the cap is removed from the insertion system. The cap is configured and dimensioned to couple with the distal end of the cartridge.
Systems and processes for inserting an intraocular lens
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.
Intraocular lens injector
An intraocular lens (IOL) injectors and associated methods are described. The IOL injectors may include a collapsible portion configured to reduce the length of the IOL injector when the collapsible portion is altered from an uncollapsed configuration to a collapsed configuration. In some instances, an IOL may be advanced from a storage location to a dwell location when the collapsible portion is altered from the uncollapsed configuration to the collapsed configuration. The IOL injectors may also include a combination push and screw drive.
