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.

NOVEL PHAKIC INTRAOCULAR LENS IMPLANTATION WITHOUT VISCOELASTICS AND INSTRUMENT THEREOF
20170354495 · 2017-12-14 ·

A novel phakic intraocular lens implantation without viscoelastics and an instrument thereof. The special designed instrument is employed to achieve a purpose of maintaining an anterior chamber only with a perfusion liquid in the surgery, so as to get rid of the influence of the viscoelastics completely. The viscoelastics are not used, so that there is no need to inject the viscoelastics or remove the viscoelastics as in traditional methods, the surgery time is shortened such that total time of surgical procedures from incision construction to incision hydration can be reduced to only 1˜3 minutes, and viscoelastic-related complications, such as postoperative high intraocular pressure and lens opacity, are completely avoided.

HYDRAULIC DELIVERY OF SURGICAL IMPLANTS

An apparatus for delivering an implant to an eye using hydraulic fluid flow or pressure. An implant may be stored, advanced, and delivered to an eye using hydraulic fluid stored in a sterile container through a hollow advancement plunger. The plunger may rigidly advance the implant to a sealed position in a first phase, and then the implant may be advanced into the eye via hydraulic pressure or fluid flow in a second phase.

HYBRID POWER DELIVERY FOR SURGICAL IMPLANTS

A hybrid power system for delivering an implant to an eye using hydraulic fluid flow or pressure. An implant may be stored, advanced, and delivered to an eye using hydraulic fluid stored in a sterile container through a hollow advancement plunger. The plunger may rigidly advance the implant to a sealed position in a first phase, and then the implant may be advanced into the eye via hydraulic pressure or fluid flow in a second phase. The power system may provide a first cell having a first power density and a second cell having a second power density, wherein the second power density is greater than the first power density. A controller may use the first cell during the first delivery phase and the second cell during the second delivery phase.

HAPTIC MANAGEMENT FOR DELIVERY OF INTRAOCULAR IMPLANTS

An apparatus for eye surgery may comprise a nozzle having a delivery lumen, an implant bay coupled to the nozzle, and an implant disposed in the implant bay. The implant may comprise an optic body, a leading haptic, and a trailing haptic. In some examples, the implant may be an intraocular lens. The apparatus may further comprise an actuator comprising a housing and a plunger disposed within the housing and a leading splay arm operable to splay the leading haptic within the implant bay. The plunger can be operable to advance the optic body from the implant bay to the delivery lumen after the leading splay arm straightens the leading haptic.

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.
