Inside our eyes, we have a natural lens. The lens bends (refracts) light rays that come into the eye to help us see. The lens should be clear for clear vision. If your lens becomes cloudy and impairs our vision clarity ,that is what is known as Cataract.
A cataract is a clouding of the lens of the eye; cataract surgery is performed to improve vision by replacing the clouded lens with an artificial one. Cataracts affect millions of people in India each year. Most cataracts are the result of aging, though some form as a result of genetic factors, disease or injury. Cataract surgery is common, and considered safe and effective.
Why Cataract Surgery
Cataracts can cause blurry vision, and increase the glare from lights. In their early stages, cataracts usually are not troublesome but, as they thicken, surgery to remove them may be required. Typically, surgery by a trained Eye Specialist is needed because cataracts are interfering with everyday activities, or the treatment of another eye problem.
Who Should go for Cataract Surgery
Cataracts caused by aging develop gradually, and patients may not notice the early vision changes they cause. It is only when their cataracts start interfering with vision that patients may become aware of them. An ophthalmologic by an experienced Eye Doctor examination will detect cataracts, and rule out other causes for vision issues, such as glaucoma or macular degeneration. Patients who become aware of visual difficulties related to cataracts usually experience, especially at night, clouded, blurred or dim vision.
Benefits of Cataract Surgery
Cataract surgery's benefits are many, greatly enhancing the quality of life. They include the following:
Improved quality of vision (sharper images, brighter colors)
Less difficulty with routine tasks (particularly night driving)
Decreased dependency on eyeglasses
Greater independence, regardless of age or disability
Research indicates that the improved vision provided by cataract surgery reduces the risk of falls, making exercise, sports and hobbies safer. This, combined with the improved ability to read, recognize faces, and perform everyday activities with greater ease, results in improved physical health, increased sociability and longer life expectancy.
