The ciliary muscle as well as the ciliary body.
The Ciliary Muscles
Within the Eye, the Ciliary Body consists of four levels: the Ciliary Muscles; the Vascular layer; the Ciliary process, and the Ciliary Epithelium.
the lens is held vertically in the eye's interior by suspensory ligaments or more specifically called the ciliary zonule, attached to the ciliary body. so suspensory ligaments is the answer(-:
iris and ciliary muscles
the ciliary muscle is the smooth muscle of the ciliary body

The ciliary body has three functions: accommodation, aqueous humor production and the production and maintenance of the lens zonules. Accommodation essentially means that when the ciliary muscle contracts, the lens becomes more convex, generally improving the focus for closer objects. When it relaxes, it flattens the lens, generally improving the focus for farther objects. One of the essential roles of the ciliary body is also the production of the aqueous humor, which is responsible for providing most of the nutrients for the lens and the cornea and involved in waste management of these areas.
The two involuntary muscles that make up the front part of the eye are the iris and the ciliary body. The iris controls the size of the pupil, regulating the amount of light entering the eye. The ciliary body adjusts the shape of the lens, enabling the eye to focus on near or distant objects.
The IRISThe pupillary muscles located on the inner edge of the iris forms the outer boundary of the pupil. The ciliary muscles are located throughout the rest of the iris and into the ciliary body. The collarette is the region of the iris separating the pupillary muscle from the ciliary muscle. It also occupies the region where the sphincter muscle and dilator muscles overlap.
