Suspensory ligaments are any ligaments that provide support to part of the body, especially an organ. For example, suspensory ligaments in the eye hold the lens in place. These ligaments, also known as the ciliary zonule, pass over the ciliary and are attached to the capsule of the lens just in front of its equator. The suspensory ligaments of the eye are purely passive; the shape of the lens is controlled by the ciliary muscles.
