    • An accommodating intraocular lens implant (10) includes an anterior floating lens unit (24), which includes an anterior lens (26); a posterior lens unit (50), which includes a posterior lens (52); an anterior rim complex (44); levers (30); and a ring (100). The levers (30) are (a) (i) in jointed connection with the anterior floating lens unit (24) at respective first longitudinal sites (60) along the levers (30), (ii) in pivotable connection with the anterior rim complex (44) at respective second longitudinal sites (62) along the levers (30), and (iii) in pivotable contact with the posterior lens unit (50) at respective third longitudinal sites (64) along the levers (30), and (b) arranged to move the anterior floating lens unit (24) toward and away from the anterior rim complex (44), in an anterior- posterior direction. The ring (100) has a diameter greater than that of the anterior lens (26), and is connected to the levers (30). The lens implant (10) is configured such that the ring (100) deforms during a transition of the lens implant (10) between a fully- accommodated state and a fully-unaccommodated state.
    • 可调节的人工晶状体植入物(10)包括前部浮动透镜单元(24),其包括前部透镜(26); 后透镜单元(50),其包括后透镜(52);后透镜单元 前缘复合体(44); 杠杆(30); 和一个环(100)。 杠杆(30)是(a)(i)在沿杠杆(30)的相应第一纵向位置(60)处与前部浮动透镜单元(24)接合连接,(ii)与前部边缘复合体 (30)处的相应的第二纵向位置(62)处,以及(iii)在沿着所述杠杆(30)的相应的第三纵向位置(64)处与所述后透镜单元(50)枢转接触,以及 b)布置成沿前 - 后方向将前部浮动透镜单元(24)朝向和远离前部边缘复合体(44)移动。 环(100)的直径大于前透镜(26)的直径,并连接到杠杆(30)。 所述晶状体植入物(10)被配置为使得所述环(100)在所述晶状体植入物(10)在完全容纳状态和完全未适应状态之间转变期间变形。
