A cataract is any abnormal opacity (cloudiness) of the lens or its outer covering (capsule). The opacity may range from a tiny spot to a total loss of transparency.
The lens is an M&M-shaped transparent structure that lies directly behind the iris and pupil. The cornea, aqueous humor, lens, and vitreous body are elements that bend (refract) light waves to form an image upon the retina. The cornea accounts for about 80% and the lens for 20% of the light-bending action.
Causes of cataracts, include heredity, metabolic defects, injuries, and aging. The rate of cataract development ranges from a few days to years.
Lens removal (cataract surgery) in animals is as successful as in humans (98% success rate). The cataract lens is removed using a state-of-the-art FX Phacoemulsification procedure and lens implantation, in most cases.
