Abstract:
An ophthalmic device includes an optic having an optic axis and a closed-loop haptic structure coupled with the optic. The closed loop haptic structure includes a first hinge having a first section, a second section, and a connecting section extending between the first section and the second section. The first section has a first component extending in a first angular direction and a second component extending in a second angular direction that is opposite to the first angular direction. The closed loop haptic structure further includes a second hinge including a radial section and an axial section extending from the axial section in the first angular direction, the radial section having a cross-sectional area greater than a maximum cross-sectional area of the first hinge.
