摘要： A system for collapsing the lens loops of an intraocular lens in preparation for insertion of the lens into a human eye and forming and maintaining the lens loops in a collapsed position during the lens insertion operation. The system includes an apparatus for mating the intraocular lens with an incapsulating structure such as a wafer fabricated from viscoelastic material. The device is designed in a manner which causes the lens loops of the intraocular lens to collapse as the lens is inserted into the incapsulating structure during the mating process. In a preferred embodiment, the device may comprise a rotor element mounted on a baseplate for supporting the intraocular lens beneath the incapsulating structure, whereby the lens can be rotated or "dialed" into the incapsulating structure.
摘要翻译：一种用于塌缩眼内透镜的透镜环的系统，以准备将透镜插入人眼，并在透镜插入操作期间将透镜环形成并保持在折叠位置。该系统包括用于将眼内透镜与诸如由粘弹性材料制成的晶片的封装结构配合的装置。该装置被设计成使得在配合过程期间透镜插入到封装结构中时会导致眼内透镜的透镜环折叠。在优选实施例中，该装置可以包括安装在基板上用于将眼内透镜支撑在封闭结构下方的转子元件，由此透镜可以旋转或“拨入”到封装结构中。

摘要： An intraocular lens suitable for use as an artificial lens implant including a medial light focusing lens body, a stem protruding from the periphery of the lens body to an outer edge thereof formed as a stem footplate adapted to make contact with eye tissue, and first and second flexible members extending from opposite sides of the stem footplate. The end of each of the flexible members is formed as a flexible member footplate so that the three footplates make contact with eye tissue at equally angularly spaced positions from the center of the lens body.
摘要翻译：一种适合用作人造透镜植入物的人工晶状体，其包括内侧聚光透镜体，从所述透镜体的周边突出到其外缘的杆，其形成为适于与眼组织接触的茎脚板，以及第一和第二柔性构件从茎脚板的相对侧延伸。每个柔性构件的端部形成为柔性构件踏板，使得三个脚板在与透镜体的中心相等的角度间隔的位置处与眼睛组织接触。
