In a first aspect of the subject invention, an iris expander is provided which includes a non-metallic, unitary, multi-segmented body which is expandable from a first state to a second state. The second state defines a larger footprint than the first state with the body being defined by a plurality of segments connected by living hinges. In a further aspect, an iris expander is provided which includes a multi-segmented body that is expandable from a first state to a larger-footprint second state. At least one aperture is formed in the body with a channel extending therefrom embedded in the body such that no portion thereof is exposed externally of the body. The channel is formed to accommodate a portion of an instrument for causing adjustment of the body with avoidance of direct contact of the instrument with the tissue of the iris. |
