What is croup? Croup is a fairly common respiratory condition in children usually caused by a viral infection or allergic reaction. Croup affects the windpipe (trachea), the bronchi (airways to the lungs), and the larynx (voice box).
However, as the cataract continues to become denser, vision also becomes more cloudy, and stronger glasses or contact lenses will no longer improve sight. Cataracts typically develop gradually and are usually not painful or associated with any eye redness or other symptoms unless they become extremely advanced.
Surgery is the only definitive treatment. Cataract surgery involves removing the damaged. natural lens through a small incision, typically less than 3 millimeters or a tenth of an inch. Currently, the best way of removing a cataract is by phacoemulsification, which uses ultrasound. to safely break up the cataract.
