    • A haptic (30, 50, 59, 69, 89) is provided for use in an accommodating intraocular lens. The haptic has multiple filaments, each connected to the edge of the optic (28,48,58,68,88,98,108) at one end. Each filament has a shape that conforms to an equatorial region of the capsular bag (18). The haptic couples the forces exerted by the capsular bag of the eye (10) 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 (66) joining the filaments at the optic end, and may optionally have a connecting ring (62) that joins the filaments at the end opposite that of the optic.
    • 提供用于容纳人工晶状体的触觉(30,50,59,69,89)。 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(28,48,58,68,88,98,108)。 每个细丝具有符合囊袋(18)的赤道区域的形状。 触觉件将由眼睛(10)的囊袋施加的力在径向地放置到光学器件的边缘处,产生光学器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处连接细丝的薄膜(66),并且可以可选地具有连接环(62),所述连接环在与光学元件相对的端部连接长丝。
