摘要：An intraocular lens is disclosed, with an adjustable optic that changes shape inresponse to a deforming force exerted by the zonules of the eye. A haptic supports theoptic around its equator and couples the optic to the capsular bag of the eye. The hapticmay include a cap on the anterior and/or posterior surfaces of the lens. The lens mayinclude a force transfer member, such as a hinge, that couples forces from the haptic tothe cap, so that a radial force on the haptic changes the curvature of the cap. The hapticand optic may be refractive index-matched. The cap may be made of the haptic material,which is stiffer than the optic material, and can influence the deformation of the lensduring accommodation. A cap on the anterior surface may produce an axial movement ofthe lens in an anterior direction during accommodation. The cap may also protect thesurfaces of the optic during handling and installation. The posterior surface of the lensmay be shaped so that it does not significantly offset the contributions of the anteriorsurface during accommodation.
