    • An accommodating intraocular lens IOL (10) including a peripheral non-optic portion comprising haptics (12) and (14). The IOL also includes an optic portion including anterior lens element (16), intermediate layer (18) which comprises actuator (20), and substrate, or posterior element (22). ' Anterior element (16) is bonded to intermediate layer (18) at its periphery. The anterior element, may also be bonded to actuator (20). The intermediate layer is also bonded to posterior element (22). The inner surface of haptics (12) and (14) define interior volumes (24) which are in fluid communication with active channel (26) defind by posterior element (22) and intermediate layer (18). As shown, actuator (20) is integral with intermediate layer (18). Posterior element (22) is molded with buttresses (11) which include a buttress bore (13) therethrough. The haptics have a haptic attachment element (15) which is sized and shaped to fit within buttless bore (13).
    • 包括包括触觉件(12)和(14)的外围非光学部分的适应性眼内透镜IOL(10)。 IOL还包括光学部分,其包括前透镜元件(16),包括致动器(20)的中间层(18)和基底或后部元件(22)。 '前部元件(16)在其周边结合到中间层(18)。 前部元件也可以结合到致动器(20)。 中间层也结合到后部元件(22)。 触觉件(12)和(14)的内表面限定内部容积(24),其与由后部元件(22)和中间层(18)确定的活动通道(26)流体连通。 如图所示,致动器(20)与中间层(18)成一体。 后部元件(22)由支撑件(11)模制,其中包括穿过其中的支撑孔(13)。 触觉件具有触觉附接元件(15),其尺寸和形状适于安装在无孔孔(13)内。
