Cataracts

Cataracts are a common age-related eye condition where the normally clear lens of the eye becomes clouded, causing blurred or hazy vision. Cataracts usually develop slowly and can affect one or both eyes. They are one of the leading causes of vision impairment worldwide but are highly treatable with modern surgery.

Symptoms of Cataracts

Cataracts can cause a range of visual symptoms, including:

• Cloudy, blurred, or dim vision

• Difficulty seeing in low light or at night

• Sensitivity to glare and bright lights

• Colours appearing faded or yellowed

• Needing stronger glasses prescriptions more frequently

Causes and Risk Factors

While aging is the most common cause, other risk factors include:

• Family history of cataracts

• Diabetes or other medical conditions

• Long-term use of certain medications (e.g., steroids)

• Prolonged UV exposure without eye protection

• Smoking and alcohol use

• Eye injury or previous eye surgery

Diagnosis

At Eye Doctor Clinics, our consultant ophthalmologists can diagnose cataracts through a comprehensive eye examination, which includes:

• Visual acuity testing

• Slit-lamp examination of the lens

• Dilated retinal examination

• Discussion of symptoms and their effect on daily activities

Treatment

In the early stages, cataracts may be managed with:

• Updated glasses or stronger lighting

• Sunglasses to reduce glare

• Visual aids to support daily tasks

When cataracts begin to interfere significantly with your vision or quality of life, surgery is the only effective treatment. Cataract surgery is one of the most common and successful procedures performed worldwide. During surgery:

• The clouded natural lens is removed

• It is replaced with a clear intraocular lens (IOL) implant

• Most patients notice dramatic improvement in vision and reduced dependence on glasses

Why Early Detection Matters

Cataracts progress gradually, and while they are not an emergency, timely diagnosis and monitoring are important. Regular eye exams help determine the right time for surgery, ensuring the best visual outcomes.
