Cataract (also known as cloudy vision or gray star in German)
Cataract, also known as cloudy vision, is an eye condition that causes clouding of the natural lens of the eye. This can lead to impaired vision and, in severe cases, blindness. Cataract is one of the most common eye diseases, especially in older people.
The most common cause of cataract is age, as the lens becomes cloudier over time. However, there are other factors that can contribute to the development of cataract, such as diabetes, injuries, or long-term exposure to UV radiation.
The symptoms of cataract can vary, but typically start with a gradual deterioration of vision. Affected individuals may have difficulty seeing clearly at a distance or up close, as well as problems with contrast perception and color recognition. The clouding of the lens can also result in a change in eyeglass prescription.
When cataract is diagnosed, the most common treatment method will be surgery. During the procedure, the cloudy lens is removed and replaced with an artificial lens called an intraocular lens. The surgery is usually done on an outpatient basis. Most patients can go home on the day of the surgery and recover within a few days.
Overall, cataract is a common eye disease that can lead to visual impairment. However, the diagnosis and treatment of cataract are typically uncomplicated and can help affected patients improve their vision and quality of life.
