Cataracts are a common eye condition that affects millions of people each year. If you have cataracts, you may be looking for answers. This post will answer some of the most common questions about cataracts. Keep reading to learn more!
1. What is a cataract?
A cataract occurs when the lens which lies behind the iris and pupil becomes cloudy. The lens helps to focus light on the retina, the sensitive layer of cells at the rear of your eye that transforms light into electrical impulses and sends them to the brain. A cataract can cause the lens to become opaque, blurry, or less able to focus light.
2. What causes cataracts?
Most cataracts are caused by ageing. Although they are most common in older adults, cataracts can occur at any age. Other risk factors include exposure to ultraviolet (UV) light, diabetes, smoking, medications, and previous eye injury or surgery.
3. What are the symptoms of cataracts?
Symptoms of cataracts include:
If you experience these symptoms, visit an ophthalmologist for a comprehensive eye exam. With early diagnosis and treatment, a doctor can successfully manage cataracts, and you can preserve your vision.
4. How are cataracts diagnosed?
There are several ways to diagnose cataracts. A comprehensive eye exam can reveal early signs of cataracts. During an eye exam, the doctor will check your visual acuity and look for signs of cloudiness or yellowing in the lens. In some cases, a test called a slit-lamp examination might be used to get a closer look at the lens. If cataracts are suspected, the doctor may recommend additional tests, such as an x-ray or ultrasound, to confirm the diagnosis.
5. How are cataracts treated?
Cataracts typically require surgery to be removed. During surgery, an ophthalmologist will make an incision in your eye and remove the cloudy lens. A new artificial lens will then be inserted in its place. The surgery is typically effective, and most people experience an improvement in their vision after the procedure.
6. How can I prepare for cataract surgery?
Cataract surgery is a common and relatively safe procedure. However, as with any surgery, certain risks and complications can occur. Therefore, it is important to follow your surgeon's instructions and to be prepared for the surgery. Your doctor may recommend stopping any medications that could increase bleeding, such as aspirin. You should also avoid eating or drinking anything the night before you are due to undergo surgery. By following these simple pre-operative instructions, you can help to ensure a successful outcome.
