Cataract surgery is a procedure of removing the natural lens of an eye that has become opaque. Cataract is developed due to metabolic changes of the crystalline lens fibers. In such a condition there is a loss of vision and transparency. During the cataract surgery, patient’s cloudy natural lens is replaced with a synthetic lens. This helps to restore the lens’s transparency.
Causes of Cataract
An eye lens is made of protein and water. Some of these proteins help to maintain the clarity of a lens. Over the period of time, these lens proteins are altered, resulting in clouding of the lens. In rare cases it is possible that cataract may occur in early childhood. It is mainly due to heredity enzyme defects and eye trauma.
Risks of developing cataract are high if a person is diabetic and smokes. Too much exposure to ultraviolet rays also increases the risk of cataract. Certain medications like topical and inhaled steroids are also risk factors for the developing cataract.
Symptoms and signs of cataract
As cataract continues to increase and progress, the vision becomes cloudier. Vision starts blurring and even the strong glasses and lens cannot improve the sight.
If your eye vision starts blurring, consult the eye specialist immediately. It can cataract and if diagnosed early, can be treated.
