Cataracts develop when the natural lens of the eye becomes cloudy, gradually diminishing vision. In the early stages, you may not notice significant changes, but over time, cataracts can blur your sight, dull colors, and make everyday activities—like reading or driving at night—more difficult. While cataracts are often associated with ageing, their impact on vision can vary from person to person.
Fortunately, with early diagnosis and proper management, clear vision can be restored.
How Cataracts Affect Vision
The lens of the eye functions like a camera lens, focusing light onto the retina to produce sharp images. It also adjusts the eye’s focus, allowing you to see objects both near and far. As cataracts develop, proteins within the lens break down and clump together, creating cloudy areas that scatter light instead of directing it precisely onto the retina. This results in blurry or distorted vision, increased glare, and difficulty seeing in low-light conditions.
Patients with cataracts often describe their vision as similar to looking through a fogged-up window. Some also experience double vision in one eye, heightened sensitivity to light, or a noticeable yellowing of colors. These symptoms tend to worsen over time, making routine tasks increasingly challenging.
Causes and Risk Factors for Cataract Development
While ageing is the most common cause of cataracts, lifestyle and environmental factors can accelerate their development. Prolonged exposure to Australia’s high UV index is a significant contributor, as UV light can damage the proteins in the eye’s lens.
Other risk factors include:
- Metabolic conditions such as diabetes, which can alter the structure of the lens.
- Smoking, which introduces harmful chemicals that degrade eye health.
- Long-term use of corticosteroid medications, often prescribed for inflammatory conditions.
- Previous eye injuries or inflammation, which can disrupt the normal function of the lens.
- Genetic predisposition, as some individuals are more prone to cataracts due to hereditary factors.
Diagnosing and Managing Cataracts at Fitzgerald Optometry
We focus on early detection to help patients maintain clear vision for as long as possible. Our comprehensive eye examinations use state-of-the-art diagnostic technology to assess the density and progression of cataracts.
During your exam, our optometrists will:
- Conduct a detailed vision assessment to determine the extent of any visual impairment.
- Perform a slit-lamp examination, using a specialized microscope to inspect the clarity of the lens and detect any cataract formation.
- Assess light sensitivity and contrast perception, as cataracts often cause glare issues, particularly in bright conditions or at night.
In the early stages, we may recommend updated glasses prescriptions, anti-glare lenses, and enhanced lighting to manage symptoms. However, as cataracts advance, these adjustments become less effective, and surgical intervention becomes the most viable option for restoring vision.
Cataract Surgery Co-Management
Cataract surgery is a safe and highly effective procedure that replaces the clouded lens with an artificial intraocular lens (IOL), allowing light to properly focus onto the retina again. This surgery is performed by an ophthalmologist and is typically completed in under 30 minutes. Most patients notice significant visual improvement within a few days to a week.
At Fitzgerald Optometry, we work closely with leading ophthalmologists in Melbourne to ensure a seamless cataract surgery experience. Our role in co-management includes:
- Pre-surgical assessments to determine the best treatment approach and discuss lens options, such as monofocal or multifocal IOLs.
- Guidance on the procedure, answering any questions and ensuring you feel informed and confident.
- Post-surgical care, monitoring your recovery and adjusting your vision care as needed.
Most patients experience minimal discomfort and a swift recovery, with long-term improvements in clarity, contrast, and colour perception.
Can Cataracts Be Prevented?
While cataracts cannot always be prevented, certain lifestyle choices can help slow their development:
- Wearing UV-protective sunglasses is essential in Australia’s harsh sun, reducing UV-related damage to the eye’s lens.
- Maintaining a balanced diet rich in antioxidants, including leafy greens, citrus fruits, and omega-3 fatty acids, supports long-term eye health.
- Managing underlying health conditions, particularly diabetes, to prevent metabolic-related lens damage.
- Avoiding smoking and excessive alcohol consumption, both of which contribute to oxidative stress in the eyes.
