摘要:
An intraocular lens is disclosed, with an optic that changes shape in response to a deforming force exerted by the zonules of the eye. A haptic supports the optic around its equator and couples the optic to the capsular bag of the eye. The haptic may be pre-stressed before the optic is placed within it. After such placement, the pre-stress may be relieved, and the haptic may produce stress in the optic. The pre-stress may produce a radial tension or a radial compression in the optic. Alternatively, once the optic is placed within the haptic, both may undergo a process that changes the size and/or shape of one with respect to the other, causing a stress within the optic. This process may produce a radial tension or a radial compression in the optic.The haptic may include an annular ring having outer and inner diameters that may depend on the stiffness of the haptic.
