Acommodating


Collins English Dictionary - Complete & Unabridged 2012 Digital Edition © William Collins Sons & Co. The accommodation reflex (or accommodation-convergence reflex) is a reflex action of the eye, in response to focusing on a near object, then looking at a distant object (and vice versa), comprising coordinated changes in vergence, lens shape and pupil size (accommodation).Your surgeon can help you decide which lens may be best for you.Text is available under Creative Commons Attribution-Share Alike (CC-BY-SA) and/or GNU Free Documentation License (GFDL).As the power of the lens becomes stronger, its ability to bend light more sharply is increased.Since the lens is monofocal, the light can only be bent to one focus point at a time.A third lens, the accommodating lens, provides a multifocal effect allowing for both near and distance focus.By moving forward in the back of the eye on small hinges, the lens can change its power in the eye, similar to the process of accommodation of the eye’s natural lens.



During accommodation, the pupil constricts to increase the depth of focus of the eye by blocking the light scattered by the periphery of the cornea.The main advantage offered by Crystalens over a traditional, monofocal lens implant is the opportunity to become less dependent on reading glasses for near activities.Activities that were once easily enjoyed without glasses, such as reading or sewing, now require a pair of reading glasses always be available.In contrast, the Crytstalens incorporates both distance and near capability into a single lens by its ability to change from distance to near power while inside the eye.

The Crystalens accomplishes this by use of two small hinges, which allow the lens to move forward and backward slightly inside the eye.

Changes in contraction of the ciliary muscles alter the focal distance of the eye, causing nearer or farther images to come into focus on the retina; this process is known as accommodation.
