Has your vision has started to become blurry or you’ve started seeing double? Moreover, if you find it’s more difficult for you to read, and colours appear duller or yellowish, you may have cataracts—a common problem among the elderly. Fortunately, cataract surgery can restore your sight and the freedom to live. However, cataract surgery NHS waiting times may be too long.

Cataract is the most common cause of visual impairment worldwide, especially among the elderly. Over the years, the crystalline lens in the eye located behind the iris become hard and cloudy. The purpose of the lens is to provide fine focus and when it becomes hard (aged 42+) affects the abilty to focus and in time to come becomes increasingly cloudy impairing vision.

Cataract surgery involves removing the cloudy natural lens of the eye replacing this with an artificial lens. It is a safe and effective procedure that can restore your vision. However, the long cataract surgery NHS waiting times can negatively impact one’s quality of life, and this is why many people choose to have private cataract surgery instead.

What is the Waiting Time for Cataract Surgery in the NHS?

More than half of the population over age of 60 have cataracts and increases in prevalence with advancing age. Cataract does not just affect the elderly – in fact, nearly 17% of people aged between 40 and 59 years and 3% of young people aged between 20 and 39 years also suffer from this eye condition. [1]

Genetic and environmental factors also influences development of cataract. Environmental factors of concern are smoking, and exposure to ultraviolet light. Diseases such as diabetes and uveitis as well as use of steroids all increase the risk of cataract formation.

The prevalence of cataracts is currently so high that cataract surgery has become the most common elective surgical procedure in the UK. The medical needs of the ageing population has resulted in significant demand on the national health system (NHS), to the point where in early 2020, in some parts of the UK, patients needed to wait several months for an initial outpatient consultation and then much longer to undergo cataract surgery in the NHS.

What’s more, COVID-19 placed additional strain on the medical system at a time when it was already difficult to meet demand for these procedures. With the pandemic, many elective surgical procedures were postponed, and the number of pending operations has continued to increase across the country with even longer cataract surgery NHS waiting times.

The Consequences of Long Waiting Times for Cataract Surgery

Visual loss from cataract is often gradual and not noticed by many until drawn to their attention by their opticians. However some report glare or poorer vision when driving at night resulting in reduced confidence. Others report difficulty in reading and performing simple tasks confidently. The risk of falls has been shown to be higher. A study conducted at the University of Ottawa Eye Institute concluded that “Patients who waited more than 6 months to undergo cataract surgery experienced more vision loss, a reduced quality of life and increased rate of falls compared with patients who had wait times of less than 6 weeks.” [2] Moreover, sometimes, falls due to vision loss from cataracts are often severe enough to require hospitalisation and end up negatively affecting one’s health and well-being [2].

Additionally the risk of developing dementia is higher in those with unoperated cataracts [3]. Along with a reduction in quality of life these are sufficiently serious enough for cataract surgery to be considered sooner rather than later.

Added to the long waiting times is another problem: many people are operated on in only one eye, even though they have cataracts in both. The current burden placed on the NHS means that it must prioritise patients based on clinical urgency, and therefore, to be considered fit for treatment, certain strict criteria must be met. Treating only one eye has its own consequences as illustrated by researchers at Queen’s Medical Centre of Nottingham who found that reducing cataract surgery waiting times for the second eye to 4 weeks instead of the routine 12-month wait reduced falls by 34%, decreased symptoms of depression, and increased the level of activity and confidence of patients. [4]

If cataracts are left untreated for many years the lens becomes very hard and more challenging to remove resulting in a higher risk of surgical complications. With increasing lens size from cataract, there is a higher risk of developing a particular type of glaucoma.

Cataract Surgery: NHS verses Private Clinic – Is There a Difference Besides Speed ?

Cataract surgery is effective, its complications are minimal, and it will make a big difference in your life, restoring not only your sight but also your freedom and safety. The NHS will safely remove the cataract and provide you with a standard monofocal lens implant. However, they do not offer refractive cataract surgery, which means that in all probability prescription glasses may well be required for astigmatism and reading.

Centre for Sight is dedicated to serving the community by offering One-stop cataract surgery at a reduced cost. This service, designed to address long NHS waiting lists, allows patients to receive timely, affordable treatment. Our comprehensive approach includes all necessary scans, diagnosis confirmation with a consultant, and the surgical procedure—all on the same day. Similar to NHS cataract surgery, we replace the cloudy lens with a synthetic monofocal or single-focus lens.

Our Refractive cataract surgery aims to reduce or eliminate the need for glasses post-surgery. This private, customized process utilizes a variety of lens types (multifocal, trifocal, or lenses with built-in astigmatism correction) to enhance far, intermediate, and near vision. The choice of lens is tailored to each patient’s eye health, optics, and lifestyle, determined through a thorough consultation and investigation.

Patients opting for private cataract surgery at Centre for Sight benefit from prompt treatment availability, often within weeks, and convenient scheduling. Additionally, private care includes extended consultations, allowing you to discuss your medical condition in detail, ask questions, and fully understand the procedure. This comprehensive approach helps reduce anxiety about the surgery and anesthesia, ensuring you feel confident and well-informed.

Furthermore, unlike the NHS, where suitable, private cataract surgery can treat both eyes on the same day, providing an added level of convenience and efficiency for our patients.

When choosing a provider for cataract surgery, it’s important to evaluate their track record to ensure you receive the highest quality care. At Centre for Sight, we prioritize your peace of mind by conducting monthly audits of our quality standards. Notably, our commitment to excellence is reflected in our posterior capsule rupture rates, which were 0% in 2020/2021 and 0.12% in 2021/2022, significantly lower than the national average of 1.5-2% in the UK. This demonstrates our dedication to maintaining the highest standards and meticulous attention to detail in every procedure we perform.
