Cataracts

A cataract is a clouding of the natural lens of your eye. The lens is a clear, disc-shaped structure behind your pupil that helps focus light onto the retina at the back of your eye. This focused light allows us to see clearly.

When a cataract develops, the lens becomes cloudy or opaque, like a foggy window. This clouding prevents light from passing through the lens properly, resulting in blurry or distorted vision.

Cataracts are a common condition, particularly as we age. While they are usually not life-threatening, untreated cataracts can lead to significant vision loss, making it difficult to perform everyday tasks like reading, driving, and recognising faces.

While cataracts are a natural part of aging, certain factors can increase your risk of developing them.

The most common cause of cataracts is simply getting older. As we age, the proteins in the lens of our eye can start to clump together, making the lens cloudy. The older you are, the higher your risk of developing cataracts.

• Diabetes: People with diabetes are more likely to develop cataracts at an earlier age.
• Eye Injuries: Trauma to the eye can damage the lens and lead to cataract formation.
• Excessive Ultraviolet (UV) Radiation: Prolonged exposure to UV rays from the sun can damage the lens and increase the risk of cataracts. Wearing sunglasses that block UV rays can help protect your eyes.
• Certain Medications: Long-term use of corticosteroids, either as eye drops or oral medications, can increase the risk of cataracts.
• Excessive Alcohol Consumption: Heavy alcohol use can also increase the risk.
• Smoking: Smoking is a major risk factor for many health problems, including cataracts. Quitting smoking is essential for eye health.

Cataracts can affect your vision in various ways, often causing symptoms that gradually worsen over time. Here are some common signs that you might be developing cataracts:

• Blurry or Cloudy Vision: Your vision may appear hazy or fuzzy, as if you are looking through a frosted window. This can make it difficult to see clearly at all distances.
• Difficulty Seeing at Night: You may find it challenging to drive at night or see clearly in low-light conditions due to increased glare and difficulty distinguishing between colours.
• Double Vision: You might see double in one eye, or things may appear to be duplicated when you look at them.
• Halos Around Lights: You may see bright rings or halos around lights, especially at night.
• Faded Colours: Colours may appear duller or less vibrant than they used to be.
• Increased Sensitivity to Glare: Bright lights, such as headlights or sunlight, may seem uncomfortably bright, causing you to squint or shield your eyes.
• Frequent Changes in Eyeglass Prescription: If you need to get new glasses more frequently than usual, it could be a sign of developing cataracts.
• Increased Nearsightedness: You may notice that your nearsightedness (myopia) has worsened, requiring a stronger prescription for reading.

While there’s no way to “cure” cataracts, there are effective treatment options available to address the clouding of your lens and improve your vision.

Cataract surgery is the only proven way to remove a cataract and restore clear vision. The procedure involves a skilled surgeon using a laser to break up the cloudy lens and replace it with an artificial lens implant. It’s a common and safe procedure with a high success rate.

While cataract surgery is the primary solution, adopting a healthy lifestyle can help reduce the risk of developing cataracts or delaying their onset:

• Quit Smoking: Smoking significantly increases the risk of developing cataracts. Quitting smoking is essential for eye health.
• Manage Other Health Conditions: Conditions like diabetes and high blood pressure can increase the risk of cataracts. Work with your doctor to manage these conditions effectively.
• Protect Your Eyes from UV Radiation: Wear sunglasses that block 100% of UVA and UVB rays when outdoors to protect your eyes from sun damage.

Before cataract surgery, your optometrist may recommend temporary solutions to improve your vision, such as:

• Glasses: Changing your prescription to account for the clouding in your lens can help with clarity.
• Contact Lenses: Contact lenses can also improve vision, but they may not be suitable for everyone with cataracts.
• Stronger Lighting: Brighter lights can help compensate for the reduced light that reaches the retina through a clouded lens.

Cataracts can impact your daily activities, but with proper management and a positive outlook, you can continue to enjoy a fulfilling life. Here are some practical tips to adapt to vision changes and ensure your well-being:

Regular eye exams are crucial for monitoring your cataracts and determining when surgery is necessary. Follow your optometrist’s recommendations closely.

• Use Brighter Lighting: Increased lighting can make it easier to see, particularly in low-light conditions. Consider using brighter light bulbs, increasing light levels in your home, and using a magnifying lamp for reading.
• Utilise Magnifying Aids: Magnifying glasses, reading magnifiers, and other aids can help you see details more clearly.
• Avoid Glare: Glare can make it difficult to see, especially for people with cataracts. Wear sunglasses outdoors, particularly during bright sunlight. Use anti-glare coatings on your glasses or consider wearing a wide-brimmed hat.
• Adjust Your Activities: You may need to adjust your activities to accommodate changes in your vision. This might involve asking for assistance, using large print materials, or adjusting the way you approach certain tasks.

Cataracts, while not a life-threatening condition, are serious in the sense that they can significantly impact your quality of life. Cataracts cause the lens of your eye to cloud, making it difficult to see clearly. While this might seem like a minor inconvenience initially, as cataracts progress, they can hinder your ability to read, drive, recognise faces, and participate in many everyday activities. Untreated cataracts can eventually lead to significant vision loss, making it challenging to navigate your surroundings and maintain your independence. Fortunately, cataract surgery is a safe and effective treatment that can restore clear vision. Early detection is crucial for preventing potential vision loss and ensuring a good quality of life.

The fastest way to deal with cataracts is through cataract surgery. It’s the only treatment that can remove the cloudy lens and restore clear vision. While there are some temporary solutions, like using stronger glasses or brighter lighting, these only provide partial relief and don’t address the underlying issue. Cataract surgery is a highly successful procedure with a fast recovery time. During the surgery, the clouded lens is removed, and a clear artificial lens is implanted in its place. This allows light to pass through the eye properly, restoring clear vision. If you’ve been diagnosed with cataracts and are experiencing vision issues, consult with your eye doctor about the best course of action. They can determine whether surgery is recommended and discuss the process and expected outcomes.
