The ciliary muscle - the driving force of accommodation

WebMar 2, 2024 · Ciliary body functions. There are three main functions of the ciliary body: accommodation, holding the lens in place and producing aqueous fluid. Accommodation refers to the eye’s ability to automatically increase its focusing power to enable the eye to see near objects clearly. This action depends on the ciliary muscle. WebLoss of elasticity of the ciliary muscle posterior attachments may be an important factor contributing to presbyopia. Even if loss of ciliary muscle mobility is not causally related to presbyopia, it may limit the performance of putatively accommodating intraocular lenses now being developed by academic and industrial groups.
