Frequently Asked Questions

A cataract is when the natural lens within your eyes becomes cloudy and limits your vision. Often they are there and you may not know that they are present until your optician tells you.

Cataracts are a clouding of the eye’s natural lens, which normally focuses light onto the retina. This clouding occurs when proteins within the lens start to clump together, obstructing clear vision. While the exact cause isn’t always known, several factors can contribute to their development: 

Age-Related Changes

• Aging: This is the most common cause. As we age, the lens naturally becomes less flexible and starts to break down.  
• Oxidative Stress: Over time, exposure to sunlight and other environmental factors can damage the lens proteins.   
• Metabolic Changes: Changes in the lens’s metabolism can also contribute to protein breakdown.

Other Risk Factors

• Diabetes: High blood sugar levels can accelerate the formation of cataracts.
• Smoking: Smoking increases the risk of developing cataracts.
• Excessive Sun Exposure: Prolonged exposure to ultraviolet (UV) radiation from the sun can damage the lens.   
• Steroid Use: Long-term use of steroid medications can increase the risk.   
• Eye Injury or Surgery: Trauma to the eye can sometimes lead to cataract formation.   
• Certain Medical Conditions: Some conditions, like Down syndrome, can increase the risk of developing cataracts.

It’s important to note: While these factors can increase the risk, not everyone who has them will develop cataracts. Regular eye exams are crucial for early detection and treatment

The only effective treatment for cataracts is surgery to remove the cloudy lens and replace it with a clear artificial lens called an intraocular lens (IOL). The operation is generally undertaken under local anaesthetic so you are awake. However, the operation is generally quick and fairly straightforward, although complications can occur that impair your vision life-long.

Your vision will gradually improve over the next few days following cataract surgery. However, it’s normal to experience some side effects such as sensitivity to light, a gritty feeling, excessive tearing, blurred vision, or even double vision. These symptoms are common and typically subside within the first few weeks.

It’s important to contact Clarity immediately if you experience any of the following:

• Significant vision loss,
• Persistent pain despite using prescribed pain medications,
• Flashes of light or the appearance of multiple spots in your field of vision, or
• Nausea and vomiting.

These symptoms may indicate a more serious issue and require prompt attention.

Following your surgery it is important that you avoid activities that could increase the risk of infection.

To minimise the risk of infection after cataract surgery, it’s crucial to:

Avoid activities that could introduce germs:

Minimise touching your eyes: It’s natural to want to rub or touch your eyes, but this can easily introduce bacteria, viruses, and other particles.

Maintain excellent hand hygiene: Wash your hands frequently with soap and water, especially before and after touching your eyes or face.

Clean frequently touched surfaces: Disinfect surfaces like door handles, phones, and taps regularly using disinfectant wipes.

Driving immediately after surgery is not advised. The use of local anaesthesia and the impact of surgery on your vision would make it difficult to drive safely. Extra light sensitivity and a loss depth perception (because binocular vision is limited) will also affect your ability to drive.

Your vision will steadily improve over a few days and typically reaches a level suitable for driving purposes after 2-4 days. You can test this yourself by checking if you can read a car number plate at 25 generous paces. If you can read the number, and you feel confident to drive, then you may do so.

Avoid Heavy Lifting:

Heavy lifting can increase pressure within your eyes, potentially interfering with healing and causing damage.

For the first 7-10 days, avoid strenuous activities like heavy gardening, running, hill walking, and carrying heavy loads (including golf bags).

Also, minimise activities that increase intraocular pressure, such as bending over to pick things up or reaching high.

Prepare Your Home:

In the week before surgery, assess your daily routine.

Identify tasks that involve bending, reaching, or straining.

Eliminate easily avoidable tasks by:

• Placing frequently used items at waist height.
• Preparing easy-to-heat meals.
• Leaving the kettle filled and a cup ready with a tea bag.
• Arranging for dog walks.

Reduce Airborne Particles:

Vacuum and clean your home thoroughly before surgery to minimise exposure to pet hair, dander, dust, and dirt.

Continue regular cleaning after surgery, but prioritise rest.

Ask your partner, friends, or children to assist with housework.

Key Points:

This information is for general guidance only.

Always follow your surgeon’s specific instructions.

If you have any concerns, contact your doctor immediately.

If you’re having cataract surgery on both eyes, there will typically be a week or two between procedures. This allows your first eye to fully recover before the second surgery. This period can feel a bit unusual as you’ll experience a temporary disparity in vision – one eye with improved sight and the other with your pre-surgery vision.

Managing Vision During the Interval:

• Spectacle Adjustment: If you wear glasses, your optician can easily remove the lens from the frame for your operated eye. This allows you to continue using your existing glasses with the correct prescription for your unoperated eye.
• Post-Operative Check-up: Once both eyes have been operated on, schedule a post-operative check-up with your optometrist. They will assess your new vision and recommend the best glasses prescription to optimise your overall vision after surgery.

You should start to notice an improvement in your vision within a few days to a few weeks after cataract surgery. However, the exact timeframe can vary depending on individual factors such as your age, the severity of your cataracts, and your overall health.

Within the first few days: Many people experience a noticeable improvement in vision clarity almost immediately after surgery. However, it’s also common to experience some blurriness or fluctuations in vision during this time as your eye heals and adjusts to the new intraocular lens (IOL).

Within the first few weeks: Your vision should continue to improve gradually over the next few weeks as the inflammation and swelling in your eye subside.

Full recovery: It may take several months for your vision to fully stabilise and reach its optimal level of clarity.

It’s important to note that this is just a general guideline, and your individual experience may vary. If you have any concerns about your vision after surgery, be sure to contact Clarity and we can monitor your progress and answer any questions you may have.

We sincerely hope you’ll be delighted with the results of your cataract surgery. For many of our patients, the long-term benefits extend beyond improved vision.

Freedom from blur and the fear of vision loss: This brings immense relief and a newfound sense of independence.

Enhanced colour perception: Many Clarity patients report experiencing colours with renewed vibrancy and clarity, often for the first time in years.

Improved overall vision: You can expect to achieve a level of sight you may not have experienced in a long time.

The degree of improvement will vary depending on the severity of your cataract. Even with early-stage cataracts, you’ll likely notice a significant improvement, such as reduced reliance on glasses.

If you’re recovering well from your cataract surgery and have no concerns, a follow-up appointment with your Clarity surgeon is not always necessary.

However, if you have any questions, concerns, or simply desire the reassurance of a follow-up consultation, please don’t hesitate to contact us. We’re happy to schedule an appointment for you.

Glaucoma is a group of eye conditions that damage the optic nerve, the nerve that carries visual information from the eye to the brain. This damage can lead to vision loss and even blindness if left untreated.

The most common type of glaucoma is called open-angle glaucoma. It develops slowly and often without any noticeable symptoms in the early stages. As the condition progresses, it can cause gradual loss of peripheral (side) vision, eventually leading to tunnel vision.

Another type of glaucoma is called angle-closure glaucoma.

This type is less common but can develop suddenly and cause severe eye pain, headache, nausea, blurred vision, and seeing halos around lights. It’s considered a medical emergency and requires immediate treatment to prevent vision loss.

There are other types of glaucoma as well, such as normal-tension glaucoma, which occurs despite normal eye pressure, and secondary glaucoma, which is caused by other eye conditions or injuries.

Glaucoma is a serious eye condition that can have a significant impact on a person’s quality of life.

If you have any concerns about glaucoma, it’s important to see an eye doctor for regular eye exams and to discuss any risk factors you may have. Early detection and treatment can help prevent vision loss and preserve your eyesight.

Glaucoma, a prevalent eye condition affecting millions globally, is often dubbed the “silent thief of sight.” This is because it can gradually damage the optic nerve without causing noticeable symptoms in its early stages. However, early detection and appropriate treatment are crucial. With timely intervention, the progression of glaucoma can be significantly slowed down or even halted. A range of treatment options, including medications, laser therapy, and surgical procedures, are available to help preserve vision and enhance the quality of life for individuals living with glaucoma.

Glaucoma occurs when intraocular pressure (IOP), the pressure within the eye, builds up to harmful levels, damaging the optic nerve. This crucial nerve transmits visual information from the eye to the brain. Optic nerve damage, a consequence of elevated IOP, can result in vision loss and even blindness. The root of the problem lies in the eye’s inability to effectively regulate the production and drainage of aqueous humor, the fluid that nourishes the eye. This imbalance leads to increased IOP, gradually damaging the optic nerve. The primary goal of glaucoma treatment is to lower IOP and slow the progression of the disease to preserve vision. By effectively managing elevated IOP through various treatment options, we aim to protect vision and ensure a good quality of life for individuals with glaucoma.

The primary treatment for glaucoma is the consistent use of eye drops. This may involve lifelong medication to effectively manage the condition and prevent further vision loss. Alternatively, laser surgery can be considered. This minimally invasive procedure is typically performed as a day case and takes only a few minutes. Another option is MIGS (Minimally Invasive Glaucoma Surgery), which can often be combined with cataract surgery to reduce eye pressure.

If glaucoma continues to progress despite eye drop therapy and laser surgery, further surgical intervention may be necessary. This typically involves creating an artificial passage through the white of the eye to allow the drainage of excess fluid.

Medication

Eye drops are often the first line of treatment for glaucoma. These medications work by either reducing the production of the fluid in the eye or increasing its drainage, thereby lowering intraocular pressure.

Laser Therapy

Laser trabeculoplasty (SLT) is a minimally invasive procedure that uses a laser to improve the drainage of fluid from the eye, reducing intraocular pressure. This treatment can be effective in some cases of glaucoma and may reduce the need for eye drops.
