摘要:
An accommodating intraocular lens comprises first and second viewing elements interconnected by a biasing member such that the viewing elements are relatively movable in response to the ciliary muscle of the eye. The viewing elements are positioned further apart when in the accommodated position than when in the unaccommodated position. The viewing elements are biased toward the accommodated position. The biasing member relatively moves the viewing elements along an optical axis of the intraocular lens. The biasing member has a standard bias force characteristic of between about 50 mg and about 750 mg.
摘要:
An accommodating intraocular lens implantable in an eye. The lens comprises an anterior portion having an anterior biasing element and an anterior optic having refractive power. The lens further comprises a posterior portion having a posterior biasing element and a posterior optic having refractive power. The anterior optic and the posterior optic are relatively moveable in response to action of the ciliary muscle to change the separation between the optics and the refractive power of the lens. The lens has an aberration-inducing force characteristic of about 70 mg to about 115 mg to allow aberration-inducing relative movement of the optics when the lens is in the eye, thereby adding optical aberration to the lens which increases depth of focus of the lens. In one variation, the lens has an aberration-inducing force characteristic of 70 mg to 115 mg. Related methods are also disclosed.
摘要:
An accommodating intraocular lens has an anterior portion including an anterior viewing element and an anterior biasing element connected to the anterior viewing element. A posterior portion has a posterior viewing element and a posterior biasing element connected to the posterior viewing element. The anterior and posterior biasing elements are connected at first and second apices. First and second distending members are connected to the posterior portion. The first and second distending members extend to locations significantly anterior of an anterior side of the posterior viewing element.
摘要:
There is disclosed an accommodating intraocular lens for implantation in an eye having an optical axis. The lens comprises an anterior portion which in turn comprises an anterior viewing element and an anterior biasing element. The lens further comprises a posterior portion which in turn comprises a posterior viewing element in spaced relationship to the anterior viewing element and a posterior biasing element. The anterior portion and posterior portion meet at first and second apices of the intraocular lens. The anterior portion and the posterior portion and/or the apices are responsive to force thereon to cause the separation between the viewing elements to change. Additional embodiments and methods are also disclosed.
