    • A rear-loaded injector cartridge for an intraocular lens (IOL) having a proximal opening that provides a haptic slot. The haptic slot receives a leading haptic of an IOL loaded therein, and temporarily retains the leading haptic while the optic of the IOL is inserted into a holding area of the cartridge. As the optic passes by, the leading haptic folds over the top of the optic, on its anterior side. The length of the haptic retention slot is sufficient to maintain the leading haptic in its anteriorly folded position while the IOL remains in holding area, typically while the cartridge is mated with a handpiece of the injector. The cartridge also has a rear or proximal cut out which advantageously keys with a similarly-sized rail on the handpiece so that the cartridge cannot be inserted in the wrong way.
    • 一种用于眼内透镜(IOL)的后装注射器盒,其具有提供触觉槽的近侧开口。 触觉槽接收装载在其中的IOL的前触觉,并且当IOL的光学元件插入到盒的保持区域中时,临时保持前触觉。 当光学器件通过时,前导触觉件折叠在光学器件的顶部上,在其前侧。 触觉保持槽的长度足以将引导触觉保持在其前部折叠位置,同时IOL保持在保持区域中,通常在墨盒与注射器的手持件配合时。 盒还具有后部或近端切口,其有利地在手持件上键入类似尺寸的导轨,使得盒不能以错误的方式插入。

    • A haptic is provided for use in an accommodating intraocular lens. The haptic has multiple filaments, each connected to the edge of the optic at one end. Each filament has a shape that conforms to an equatorial region of the capsular bag. The haptic couples the forces exerted by the capsular bag of the eye during accommodation radially to the edge of the optic, produce a diametric expansion or compression of the optic. This diametric motion distorts the optic, producing a change in any or all of the anterior radius, the posterior radius, and the thickness. These changes affect the power of the lens and/or location of the image. The haptic may optionally have a thin membrane joining the filaments at the optic end, and may optionally have a connecting ring that joins the filaments at the end opposite that of the optic.
    • 提供用于容纳眼内透镜的触觉件。 触觉具有多个细丝,每个细丝在一端连接到光学元件的边缘。 每个细丝具有符合囊袋的赤道区域的形状。 触觉装置在径向地放置到光学元件边缘的过程中耦合由眼囊的囊袋施加的力,产生光学元件的直径膨胀或压缩。 该直径运动扭曲光学元件,产生前半径,后半径和厚度中的任何或全部的变化。 这些变化影响镜头的功率和/或图像的位置。 触觉件可以可选地具有在光学端连接长丝的薄膜,并且可以可选地具有连接环,所述连接环在与光学元件相对的端部连接长丝。

    • An intraocular lens (IOL) insertion system for implanting IOLs into the eye. The insertion system includes an insertion cartridge that receives the IOL and cooperates with a handpiece. The cartridge includes a longitudinal lumen from a loading chamber to an open distal mouth that gradually narrows in dimension so as to fold the IOL into a tube for insertion through an incision in the eye. A distal tip member of a plunger rod in the handpiece enters the loading chamber of the cartridge and urges the IOL therethrough. The distal tip member has a portion that enters the folded IOL and is trapped therein for maximum control of IOL advancement. A soft tip, such as silicone, may cover a longitudinally extending portion of the distal tip to effect the IOL trapping. The distal tip member further has a portion that engages and pushes the IOL optic. The pusher portion not only ensures positive advancement of the IOL, but also limits the extent to which the distal tip member becomes trapped inside the folded IOL, thus preventing potential damage thereto.
    • 用于将IOL植入眼睛的人工晶状体(IOL)插入系统。 插入系统包括接收IOL并与手持件配合的插入盒。 药筒包括从装载室到开放的远端口的纵向内腔,其逐渐变窄的尺寸,以便将IOL折叠成用于通过眼睛中的切口插入的管。 手柄中的柱塞杆的远端部件进入筒的装载室并且通过其推动IOL。 远侧末端构件具有进入折叠的IOL并被捕获在其中的部分,以最大限度地控制IOL前进。 诸如硅树脂之类的软尖端可以覆盖远侧末端的纵向延伸部分以实现IOL捕获。 远侧末端构件还具有接合和推动IOL光学元件的部分。 推动器部分不仅确保了IOL的积极进展,而且限制了远侧末端构件被夹在折叠IOL内的程度,从而防止对其的潜在损害。
