Abstract: An accommodating intraocular lens includes an optic portion a haptic portion and a backstop. 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. Forces applied to the haptic portion may result in fluid displacements from or to the haptic portion from the actuator. The backstop provides support to the haptic so that bulk translation of the haptic is prevented in response to the forces applied by the capsular sac.

Abstract: 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.

Abstract: A flexible, surface electromyographic electrode apparatus is provided for use on a surface of biological tissue to measure bio-electric signals thereof. The electrode apparatus includes a conductive signal electrode device having a signal contact adapted to directly contact the surface of the biological tissue, and a signal transmission portion electrically coupled to the signal contact. A conductive ground electrode device of the electrode apparatus includes a ground contact that is adapted directly contact the surface of the biological tissue. A ground transmission portion of the ground electrode device is electrically coupled to the ground contact. The ground contact is disposed substantially about the signal contact so as to substantially surround a peripheral edge of the signal contact when both are in contact with the tissue surface. An insulation washer device is further disposed between the signal contact and the ground contact to substantially prevent conductive contact therebetween.
