INSERTION CARTRIDGES WITH REDUCED IOL STRESS

An intraocular lens (IOL) injector cartridge having one or more modifications from conventional designs which reduce stress and strain in the optic of the IOL during passage through the cartridge. One change includes adding axially-oriented ribs in a funnel portion of the cartridge to enable the cartridge wall to flex outward during passage of the IOL, which is compressed to a great degree in the cartridge lumen. Another modification involves providing a longitudinal step along a segment of the inner lumen which biases one free edge of the optic to tuck or dive under the other free edge and encourage spiral folding as the IOL progresses along the gradually narrowing lumen. The third option is modifying the shape of the lumen within the extreme distal end of the cartridge where the lumen is smallest so that it is neither circular nor oval. Each or all of these modifications may be incorporated into a single cartridge.

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.

INTRAOCULAR LENS DELIVERY SYSTEM

A semi-loaded intralocular lens injector device and related methods are described. In some embodiments, an intraocular lens is stored in a non-deformed configuration in a cassette separate from the injector device. When the cassette is inserted into a cavity of the injector device, a projection extending into the cavity deforms the intraocular lens into a predetermined configuration.

Injector assembly employing compressed gas and a mechanical brake for presenting an intraocular lens to a patient

An intraocular lens (IOL) injector is configured for single hand operation and employs a compressed gas to provide a motive force to present an IOL to a surgical site. The IOL injector includes a mechanical brake coupled to a plunger to preclude translation of an IOL absent operator input. The mechanical brake provides for selectively varying the speed and translation of the plunger, and hence IOL during presentation of the IOL to a patient. The IOL injector can also include at least a first stop, which halts movement of the plunger at a predetermined position. The at least first stop is then moved to a passing position, thereby allowing further operator controlled translation of the plunger to present the IOL to the surgical site.

IOL FOLDING DEVICE

An intraocular lens (IOL) folding device is described.

Intraocular lens delivery device and method of use

An IOL delivery device which has a macro movement actuator which is actuateable to move an IOL into position in the device for the IOL to be delivered, and a micro movement actuator comprising at least one pivotable member which is pivotable to deliver the IOL to the eye. The pivotable member may comprise one or more wheels that are rotatable using one's finger.

Haptic optic management system utilizing rotating cams

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.

INTRAOCULAR LENS INSERTION SYSTEM

A system for delivering an intraocular lens (IOL) is disclosed, including: a handpiece including a barrel defining an elongate passage, a pushrod disposed inside the elongate passage, and a plunger coupled to the pushrod; and a delivery unit coupled to a first end of the barrel, the delivery unit including a delivery tube and a lens holder coupled to the delivery tube, the lens holder including a lead haptic shelf arranged to receive a lead haptic of an IOL that is contained inside the lens holder, wherein the lead haptic shelf is configured to fold the lead haptic of the IOL over a body of the IOL while permitting the IOL to travel under the lead haptic shelf when the IOL is displaced from the lens holder to the delivery tube by the pushrod during delivery of the IOL into a patient's eye.

INJECTOR ASSEMBLY FOR INSERTING AN INTRAOCULAR LENS
20220362008 · 2022-11-17 ·

An ophthalmosurgical injector includes a cannula, a barrel, an outer plunger mounted in the barrel and together with the barrel delimiting a barrel cavity arranged in the barrel, and into which an intraocular lens can be introduced, and an inner plunger mounted in the outer plunger and together with the outer plunger delimiting an outer plunger cavity arranged in the outer plunger and into which a liquid can be introduced. The injector is configured such that a first movement, executed by the inner plunger relative to the outer plunger such that the outer plunger cavity becomes smaller, causes the liquid to flow from the outer plunger cavity into the barrel cavity, and a second movement, executed by the outer plunger relative to the barrel such that the barrel cavity becomes smaller, causes the intraocular lens to be pressed out of the barrel cavity and into the cannula.
