    • 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.
    • 可植入眼中的适应性眼内透镜。 透镜包括具有前偏置元件的前部和具有屈光力的前光学元件。 透镜还包括具有后偏置元件的后部部分和具有屈光力的后视镜。 前视神经和后视镜相对于睫状肌的作用相对移动以改变光学元件与透镜屈光力之间的分离。 透镜具有约70mg至约115mg的像差诱导力特征,以允许当透镜在眼睛中时像差引起的光学元件的相对运动,从而增加透镜的光学像差,从而增加透镜的焦深的光学像差 。 在一个变型中,透镜具有70mg至115mg的像差诱导力特征。 还公开了相关方法。
