摘要:
An accommodating intraocular lens includes an optic portion, a haptic portion. The optic portion of the lens includes an actuator that deflects a lens element to alter the optical power of the lens responsive to forces applied to the haptic portion of the lens by contraction of the ciliary muscles and a secondary deflection mechanism. Movement of the lens element by the actuator causes the lens element to deform and the secondary deflection mechanism causes the lens to further deform.
摘要(中):
容纳人造眼镜包括光学部分,触觉部分。 透镜的光学部分包括使透镜元件偏转的致动器,其响应于通过睫状肌的收缩和次级偏转机构施加到镜片的触觉部分的力而改变透镜的光焦度。 透镜元件由致动器的移动导致透镜元件变形,并且次级偏转机构导致透镜进一步变形。
