Crystalens accommodating intraocular lens
When the ciliary muscle contracts it bulges backwards and increases pressure behind the lens, thus forcing the optic forward.
Relaxation of the muscle increases the pressure in front of the lens to move the optic backwards, thus enabling the lens to focus naturally at all distances.
This is known as loss of accommodation, or presbyopia.
The Crystalens® lens was researched and developed specifically to help correct the aging vision condition and was engineered with a hinge design that allows the optic to move as your focus on an image changes.
(Bausch Lomb) An irregularity in the shape of the lens.Another advantage is that optical performance is unaffected by pupil size or location of the optic due to uniform center-to-edge power, helping to have more consistent vision in various environments.The Crystalens® is attached to the ciliary muscle, a circular muscle that surrounds the lens in the eye.If you are like most patients who have the Crystalens®, you can expect to enjoy the “luxury of sight” near, far, and everywhere in between and see everything more clearly.Your focus will be sharper than it has been in years, and you can expect to see improvements over time.
