How does the CrystaLens work?
The CrystaLens accommodating intraocular lens is engineered
with a hinge designed to allow the optic, or part of
the lens that you see through, to move back and forth
as you constantly change focus on images around you.
All other IOL's are fixed and stationary within the
eye - a design that prevents them from accommodating,
or moving to focus. The CrystaLens is unique
because it uses a hinged design to allow for movement of the optic; this brings
near, intermediate and distant objects into focus.
Near and intermediate vision result from the action of the focusing
muscle in the eye, called the ciliary muscle. This muscle changes the
power and thus the focus of the natural lens. This enables the eye
to automatically focus to provide distance, intermediate, and near
