Myopic patients having decreased ocular rigidity transmits greater force of contraction of ciliary muscles to the choroid and sclera.
Differences in the diameter of the ciliary muscles used to focus at different distances may have important implications for providing patients with a "customized" IOL fit.

The focusing muscle, however, requires the availability of chromium and supporting nutrition to potentiate the uptake of adequate glucose fuel to power the ciliary muscles inside the eye.
Positive accommodation refers to the time required for the ciliary muscle to contract sufficiently to change the focus from distance vision to close-up or near vision.
59) Furthermore, the contraction of the chick ciliary muscle and thus accommodation in the chick is not affected by atropine administration.
Pilocarpine acts at parasympathetic muscarinic receptor site to cause ciliary muscle spasm and pupillary miosis.
21) Accommodating IOLs operate with contraction of the ciliary muscle, which remains functional until late in life.
Alongside, supportive therapy like pain medications are given, including topical cycloplegics like atropine or homatropine to dilate the pupil and thereby stop spasms of the ciliary muscle.
AcrySof(R) ReSTOR(R) IOL does not rely on the ciliary muscle, which weakens with age, to enable the eye to quickly change focus to see objects at near, intermediate and far distances.
Topical cydoplegics/mydriatic eye drops are used to control pain caused by ciliary muscle spasm which frequently occurs with acute anterior uveitis and to break or prevent synechiae.
