Cataracts

Most people qualify for free cataract surgery on the NHS, with eligibility determined by your local Integrated Care Board based on your eye test results and how your vision affects daily life. Private cataract surgery offers more lens choices and flexibility, with costs depending on your location, clinic, lens type, and surgical technique. Standard lenses improve vision at one distance, while multifocal and Extended Depth of Focus lenses reduce the need for glasses. Advanced procedures like Refractive Laser-Assisted Cataract Surgery are usually more expensive. Private cataract surgery typically costs between £2,000 and £4,000 per eye.

Cataracts are very common but not inevitable. Around 30% of people over 65 and half of those over 75 have cataracts or have had cataract surgery. Most cataracts are age-related and develop slowly, so regular eye tests are important to detect them early. If cataracts do affect your vision, surgery to replace the lens is quick, safe, and painless, usually taking just 5 to 10 minutes per eye.

Cataracts are primarily a result of aging, as proteins in the eye’s lens break down and cause clouding. While the exact trigger is unknown, they affect roughly 30% of adults over age 65.  
Primary Causes & Risk Factors  
Lifestyle: Smoking and excessive alcohol consumption.  
Medical: Diabetes and long-term steroid use.  
Trauma: Previous eye injuries or surgeries.  
The Three Main Types  
Subcapsular cataracts, which form at the back of the lens – people with diabetes or people taking steroids have a higher risk of developing a subcapsular cataract. 
Nuclear cataracts, which form in the centre of the lens – these are usually associated with ageing.  
Cortical cataracts, which form at the edge of the lens and then gradually increase in size and make their way to the centre of the lens – these are characterised by white blotches and again, are usually associated with ageing. 

A cataract occurs when the lens of your eye becomes cloudy, affecting your vision. The lens, which works like a camera lens, is mostly protein and water; over time, the protein can clump together and form a cataract. Age-related cataracts develop gradually and can be influenced by factors such as eye injury, previous surgery, diabetes, long-term steroid use, smoking, and excessive alcohol consumption.

Cataracts usually affect both eyes but may progress at different rates. Symptoms include blurry or cloudy vision, difficulty seeing at night, faded colours, glare, halos around lights, and frequent changes in glasses or contact lens prescriptions. Cataracts can also affect driving if vision standards are not met. The only treatment is cataract surgery, which is quick, safe, and usually takes around 15 minutes.

No, cataracts cannot improve vision. Over time, the protein in the eye’s natural lens clumps together, causing cloudiness and progressive vision loss. Early symptoms, like mild blurriness or difficulty reading in dim light, may be managed temporarily with brighter lighting or updated glasses.

However, once vision is significantly affected, cataract surgery is the only way to restore clear eyesight. Post-surgery, most patients experience a marked improvement in vision compared to before the operation. 

Age-related cataracts are rarely directly hereditary, though having close family members with cataracts may slightly increase your risk. Cataracts can also be congenital, meaning they are present at birth, sometimes due to inherited factors but often caused by other issues during pregnancy such as infections, metabolic problems, trauma, or reactions to medications.

Congenital cataracts cause cloudy vision in the affected child and require surgery, usually within the first two months of life. Unlike adult cataract surgery, children may need lens replacements as they grow, and vision correction with contact lenses or glasses is often used after surgery.

Cataracts usually develop with age, but they can appear earlier in people who have had an eye injury or other risk factors. The speed at which cataracts progress varies, and it’s not possible to predict exactly when they will start affecting your vision or require surgery.

An optician can monitor your eyes through regular tests, assess the type of cataract, and provide an informed estimate of progression, but this can never be guaranteed. Age-related cataracts often develop slowly, so early detection through routine eye exams is important for timely treatment.

A stroke can affect your vision if it damages the parts of your brain that process visual information, potentially causing blurred vision, double vision, or visual field loss. These problems may be temporary or permanent depending on the stroke’s severity and location. However, there is no evidence that a stroke causes cataracts. If you experience vision changes after a stroke, the Stroke Association can provide advice and support.

Cataracts form when proteins in the eye’s lens break down and clump together, causing clouded vision. Prolonged exposure to UV rays accelerates this process, increasing the risk of cataracts. You can reduce this risk by wearing hats and sunglasses with 100% UVA and UVB protection, ideally wrap-around styles to shield the entire eye. UV rays are present year-round, including in winter, and can reflect off snow or water, so protection is always important. Regular eye tests help detect cataracts early and ensure timely treatment.

Cataracts are mostly age-related and cannot be completely prevented, but you can reduce your risk by following these steps:

• Stop smoking, as it increases the likelihood of developing cataracts.
• Limit alcohol consumption, since excessive drinking is linked to cataract formation.
• Wear sunglasses with UV400 protection to shield your eyes from harmful UV rays.
• Eat a healthy, balanced diet rich in vitamins, minerals, and antioxidants from fruit and vegetables to support eye health.
• Have regular eye tests to detect cataracts and other eye conditions early.

By adopting these habits, you can help protect your eyes and reduce your risk of cataracts.

If cataracts are left untreated, vision will gradually worsen and can eventually lead to blindness. Age-related cataracts occur when proteins in the eye’s natural lens break down and accumulate, causing clouding that reduces clarity over time. This process may be slow, and early symptoms can be subtle, but without surgery, vision will continue to deteriorate. Cataract surgery is a safe, quick, and painless procedure widely available on the NHS, and it is the only effective way to restore clear vision once cataracts affect your eyesight.
