Whether you’re contemplating surgery for the first time or seeking guidance on when to schedule your procedure, this guide is tailored to empower you with the knowledge needed to make informed decisions about your eye health.
Understanding Cataracts
A cataract is a common eye condition characterised by the clouding of the eye’s natural lens, leading to a progressive decline in vision clarity. Cataracts are most commonly associated with ageing. As we grow older, the proteins in the lens can clump together, causing clouding and opacity. Other potential causes include medication, UV exposure, trauma and medical conditions such as diabetes.
A cataract causes a gradual reduction in vision, decreased colour perception, reduced night vision and an increase in glare. These symptoms can significantly impact daily activities, such as reading, driving, and recognising faces.
Cataracts are very common, especially as people age. They are one of the leading causes of vision impairment and blindness worldwide. The risk of developing cataracts increases significantly with age, but they can also result from other factors such as injuries, certain diseases, or long-term use of steroid medications.
When is Cataract Surgery Recommended?
Cataract surgery is usually recommended when cataracts affect quality of life.
Key indicators that may suggest you need cataract surgery include decreased visual acuity, having a hard time with tasks like reading or driving, problems with glare, and loss of colour intensity.
Here are some key indicators that suggest it may be time to consider cataract surgery:
-

Visual Symptoms that you may need cataract surgery:
The most common indication for cataract surgery is experiencing visual symptoms that interfere with daily activities.
These symptoms may include:Blurred vision
Difficulty seeing clearly, especially at night or in low-light conditions is a sign that you may need cataract surgery. This is sometimes described as vision loss by some patients. If you are experiencing blurry vision, deteriorating vision or vision loss, this may be due to a number of factors, but cataracts are one potential cause.
Glare sensitivity or light sensitivity
Increased sensitivity to bright lights or glare, making it challenging to drive at night or see in brightly lit environments, is another indicator you may be ready for cataract surgery. As with blurred vision, glare sensitivity or light sensitivity can be caused by a number of things, but cataracts may be behind them.
Seeing Halos around lights
Seeing halos around lights, particularly when driving at night, is another indicator that you may have cataracts that have advanced to a level where you need surgery.
Reduced contrast sensitivity
Difficulty distinguishing between shades of colours or perceiving contrasts between objects is another symptom that you may have cataracts that need surgery.
Double vision
If you are experiencing double vision, seeing double images or ghosting of images, this may be an indication that you may need cataract surgery. Double vision can affect depth perception and coordination. -
Impact on Daily Activities
If cataracts hinder activities such as reading, driving, watching television, or performing routine tasks, it may be time to consider surgery. Cataracts can significantly impede one’s ability to carry out essential daily functions, affecting independence and overall quality of life. Having a cataract forms quite a barrier for many people, and when this starts to impact significantly on your daily activities, it is one of the biggest warning signs that you may need cataract surgery soon.
-
Decline in Visual Acuity
A decline in visual acuity, measured by an eye exam, indicates worsening cataracts. When corrective lenses no longer provide adequate vision improvement, surgery may be necessary to restore clarity and sharpness to vision. For most who have cataract surgery, the visual outcome is significant.
-
Safety Concerns
For individuals whose cataracts pose safety risks, such as difficulty driving due to impaired vision or an increased risk of falls due to poor depth perception, cataract surgery may be recommended to enhance safety and mobility.
-
Impact on Other Eye Conditions
In some cases, cataracts may exacerbate other eye conditions, such as age-related macular degeneration or diabetic retinopathy. Addressing cataracts through surgery can improve the management of these coexisting eye conditions and prevent further vision deterioration.

How do you know when your cataract is ready for surgery?
Determining when your cataract is ready for surgery primarily depends on how much the cataract is affecting your daily life and vision quality. Surgery is generally considered when the cataract begins to cause safety risks, or pose significant difficulties.
Cataract surgery isn’t typically urgent unless the cataract significantly impairs vision. Many people with early-stage cataracts do not experience vision problems severe enough to require surgery. This being said, however, in many cases, delaying surgery until the cataract is very developed is no longer recommended. Modern cataract surgery is very safe and effective, and waiting until the cataract is highly advanced is unnecessary and can even pose risks by increasing the likelihood of accidents or falls due to poor vision.
A comprehensive eye examination by a qualified ophthalmologist is crucial to assess the development and impact of the cataract and to discuss the best timing for surgery based on your specific symptoms and lifestyle needs.

Decisions to Make Before Cataract Surgery
It’s important to understand the different options before deciding on cataract surgery.
For example, there are different types of artificial lenses (Monofocal, Multifocal, Toric) that can be used in surgery. How to choose the right artificial lens for you depends on a number of factors, which an eye specialist can discuss with you.
Consideration of the timing of the surgery also needs to happen, taking into account the progression of the cataract, your readiness for the procedure and recovery, and the recommendation of your eye doctor.
It’s also important to choose the right cataract surgeon when deciding on cataract surgery.
Choosing the right intraocular lens (artificial lens) technology
Choosing the right intraocular lens (IOL) technology for cataract surgery is an important decision that can significantly impact visual outcomes and overall satisfaction with the procedure.
Here are several factors to consider when selecting IOL technology:
-
-
Visual Goals and Lifestyle
Understanding your visual goals and lifestyle preferences is crucial when choosing an IOL. Some people prioritise distance vision for activities like driving or watching TV, while others may prioritise near vision for reading or hobbies. Discuss your lifestyle and visual expectations with your ophthalmologist to determine the most suitable IOL option.
-
Monofocal vs. Multifocal IOLs
Monofocal IOLs provide clear vision at one fixed distance (usually distance vision), while multifocal IOLs offer a range of vision, including near, intermediate, and distance vision. Multifocal IOLs can reduce dependence on glasses for various activities but may cause more visual disturbances such as glare or halos compared to monofocal IOLs.
-
Extended Depth of Focus (EDOF) IOLs
EDOF IOLs are a newer category of lenses designed to provide an extended range of vision with reduced visual disturbances compared to multifocal IOLs. They aim to improve both distance and intermediate vision while maintaining good contrast sensitivity.
-
Toric IOLs for Astigmatism Correction
If you have astigmatism along with cataracts, toric IOLs may be recommended. These specialised lenses can correct astigmatism, reducing the need for glasses or contact lenses after surgery. Toric IOLs come in both monofocal and multifocal designs.

How to choose the right eye surgeon for your cataract surgery
In order to choose a surgeon for your cataract procedure you should take the advice of your GP or optometrist. They will have experience in referring patients for cataract surgery and will see first hand the results of local surgeons.
Choose a surgeon who communicates openly, listens to your concerns, and takes the time to address your questions. A good surgeon-patient rapport is essential for building trust and ensuring that you feel comfortable and informed throughout the surgical process.
