Cataracts are a common eye condition that can significantly impair vision, primarily affecting older adults. Understanding what causes cataracts is essential for prevention, early detection, and effective treatment. In this blog post, we will explore the main causes of cataracts, the benefits of cataract surgery, and how you can live your best life after the procedure.

Understanding cataracts

A cataract is a clouding of the eye’s natural lens, which lies behind the iris and the pupil. This condition develops when proteins in the lens clump together, forming a cloudy area that interferes with light passing through the lens. As a result, vision becomes blurry, hazy, or less colourful.

Main causes of cataracts

• Ageing
  The most common cause of cataracts is ageing. As we age, the proteins in the eye’s lens begin to break down and clump together, leading to the formation of cataracts. Most people start to develop cataracts around the age of 60, although they may not notice significant vision problems until later.
• Genetics
  Family history can play a role in the development of cataracts. If your parents or siblings have had cataracts, you may be at a higher risk of developing them as well.
• Medical Conditions
  Certain medical conditions, such as diabetes, increase the risk of cataracts. Diabetic patients are more likely to develop cataracts at an earlier age, and their progression can be faster.
• Eye Injuries
  Previous eye injuries or inflammation can contribute to the development of cataracts. Traumatic cataracts can form immediately after an injury or years later.
• Sun Exposure
  Prolonged exposure to ultraviolet (UV) radiation from the sun can damage the proteins in the lens, increasing the risk of cataracts. Wearing sunglasses that block UV rays can help protect your eyes.
• Medications
  Long-term use of certain medications, such as corticosteroids, can lead to the development of cataracts. If you are on such medications, regular eye check-ups are essential.
• Lifestyle Factors
  Smoking and excessive alcohol consumption are linked to an increased risk of cataracts. Both smoking and alcohol can accelerate the breakdown of proteins in the lens.
• Poor Nutrition
  A diet lacking in essential nutrients, such as antioxidants (vitamin C and E) and omega-3 fatty acids, can contribute to the formation of cataracts. Eating a balanced diet rich in fruits, vegetables, and healthy fats can support eye health.

Symptoms of Cataracts

Recognising the symptoms of cataracts early can lead to timely treatment and better outcomes. Common symptoms include:

• Blurred or cloudy vision
• Difficulty seeing at night
• Sensitivity to light and glare
• Seeing “halos” around lights
• Colours appearing faded or yellowed
• Double vision in one eye
• Frequent changes in prescription glasses or contact lenses

Benefits of Cataract Surgery

Cataract surgery is the only effective treatment for cataracts. During the procedure, the cloudy lens is removed and replaced with a clear artificial lens (intraocular lens or IOL). Here are the benefits of cataract surgery:

• Restored Vision
  Cataract surgery can significantly improve vision, making it clearer and sharper. Most patients experience a dramatic improvement in their ability to see.
• Enhanced Quality of Life
  Improved vision allows you to perform daily activities with ease, such as reading, driving, and recognising faces, leading to a better quality of life.
• Increased Independence
  With clearer vision, you can regain your independence and confidence in performing tasks without relying on others.
• Better Safety
  Improved vision reduces the risk of falls and accidents, especially in older adults, making your environment safer.
• Vivid Colours
  After cataract surgery, colours may appear more vibrant and brighter, enhancing your visual experience.

How to live your best life after cataract surgery

Post-surgery, there are several ways to ensure you get the most out of your improved vision:

• Follow Post-Operative Instructions
  Adhere to your surgeon’s advice and use prescribed eye drops to promote healing and prevent infection.
• Regular Eye Check-Ups
  Schedule regular eye exams to monitor your eye health and ensure the success of the surgery.
• Protect Your Eyes
  Wear sunglasses with UV protection to shield your eyes from harmful rays.
• Maintain a Healthy Diet
  Eat a balanced diet rich in fruits, vegetables, and omega-3 fatty acids to support ongoing eye health.
• Stay Active
  Engage in regular physical activity to boost overall health and well-being.
• Avoid Smoking
  Quit smoking to reduce the risk of further eye issues and promote better health.
