Cataracts And Treatment
All About Cataracts And Their Treatment
Cataracts are so incredibly common that, by age 80, more than half of all Americans will either have cataracts currently or have had one removed.
When looking at an object, light is received through the pupil. It is then focused onto the back of the eye, where there is a collection of light-sensitive cells called the retina. A cataract occurs when the eye’s normally clear lens becomes fogged up, making it hard or even impossible for light to travel properly through the lens and be clearly focused on the retina.
Treatment Of A Cataract Varies
In cases in which clouding is minimal, vision is hardly affected and a slight change in eyeglasses prescription may be enough. Alternatively, if all or a large part of the lens is clouded, surgery is required to restore sight. Cataract surgery involves the removal of the cloudy natural lens and replacement of the natural lens with an artificial lens made of plastic, silicone or acrylic. The surgery is extremely low risk and is normally done as an outpatient procedure without the overnight stay.
