Abstract
An accommodative intraocular lens (IOL) and a method of implanting the lens are disclosed. The lens is made from a soft shape memory material and has a first configuration associated with a first diopter power. When the lens is implanted into the capsule in the eye, the interaction between the lens and the capsule, based on their relative sizes, causes the lens to take on a second configuration with an associated second diopter power. The force placed on the capsule by tensioning and untensioning of the zonules causes the lens to move between its first and second configurations and diopter strengths, thereby providing lens accommodation to the patient.
