摘要:
An accommodating intraocular lens includes an anterior portion having ananterior viewing element and a posterior portion having a posterior viewingelement, theviewing elements positioned for relative movement along an optical axis inresponse tociliary muscle action. The anterior and posterior portions meet at first andsecondapices of the lens located on a transverse axis of the lens, and at least oneof theseportions has a separation member with a contact surface for preventing contactbetweenthe viewing elements. The contact surface contacts an opposing surface of theintraocular lens over a contact area when the portions are at the minimumseparationdistance. The entirety of the separation member is located outside aprojection of aperiphery of the refractive zone out of contact with one of the anteriorposterior portionswhen the viewing elements are separated by a distance greater than the minimumseparation distance.
