Zonules

If fibers, called zonules, that hold the lens in a suspended position and allow it to change shape during accommodation are damaged, or the ciliary muscles that relax the zonules are weak, Crystalens may not respond well. ❋ Unknown (2009)

With intracapsular cataract extraction, the entire lens is removed and the zonules give way, releasing the entire capsule while leaving no remaining supporting structure behind the iris. ❋ Crystalcane36 (2010)

Ciliary body • Connects the choroid with the iris • Has three parts including: - The ciliary muscle is ring shaped muscle that controls the shape of the lens (accommodation) - The ciliary process is the attachment site for the zonules and produces the aqueous in the pars plicata - The ciliary ring is attached to the choroid and is composed of the pars plana. ❋ Unknown (2009)

Lens • Transparent, biconvex structure, held in place by ciliary zonules • Composed of 6 layers • Refracts light • Nutrition comes from aqueous humor … insoluble deposits of proteins build up over time = cataracts - A clouding of the lens and capsule • Live long enough and you WILL have some degree of cataract • cataracts also caused by other agents ❋ Unknown (2009)

A wide-field anterior segment B-Scan gives practitioners an unprecedented view of the lens apparatus, including zonules and ciliary muscles, areas nearly impossible to visualise with other ultrasound systems.
