Cataract Surgery
A cataract occurs when your natural crystalline lens, inside the eye becomes cloudy. This progressively blurs your vision and reduces light entering the eye. Cataract surgery is then performed to remove the cataract, which is clouding vision, and replace it with a new clear acrylic intraocular lens. Due to the vast range of intra-ocular lenses, it is also an opportunity to reduce or eliminate the need for glasses or contact lenses. During cataract surgery it is possible to simultaneously correct your short sightedness (myopia), long sightedness (hyperopia) and / or astigmatism for true freedom of vision.
What is a cataract?

To see clearly light has to focus on the retina. To do this, eyes use two inbuilt lenses to bend light to the correct focal point. These are the cornea, the clear dome at the front of the eye, and the second is the natural, crystalline lens inside the eye.
A cataract forms when this natural lens becomes less flexible and then cloudy. This has three effects:
- Reducing the amount of light entering the eye
- Scattering the light – blurring your vision and causing halos and glare most noticeable at night
- A large cataract in a smaller eye can also cause the pressure inside the eye to rise and glaucoma.


Cataract surgery is one of the most common surgical procedures in the world with excellent safety records. The procedure involves removing the contents of your cloudy natural lens and then inserting a new usually acrylic lens into the casing that is deliberately left behind.
This new lens allows light back into the eye to form a sharp point of focus on the retina once again.
Numerous lens options are available.
Enhanced Lenses
This range of lenses includes implants that correct distance and intermediate vision to reduced day to day glasses dependency. There are numerous lenses for Mr Darcy to choose from including monofocal, monofocal plus and extended range of focus lenses, all of which will be calculated with a toric correction as standard, if you have any astigmatism.
Please bear in mind, a pair of spectacles may be required for some very close tasks or for reading in low lighting.
Premium Lenses
Our premium lens replacement procedure is aimed to achieve good vision at all distances – near, intermediate and distance, to alleviate the need for spectacles. There are numerous options available including trifocal and the latest “spiral” lens technology, all of which offer a toric correction and is included, if required.
Careful consideration to a patients lifestyle and vision needs while considering the correct type of lens.
Monofocal Lenses
These are the lenses commonly offered by private medical insurance for cataract surgery:
Monofocal lenses provide a single point of focus, effectively improving a patient's vision and addressing the symptoms of cataracts. These lenses are designed to correct either short-sightedness or long-sightedness, but they do not address astigmatism, which means patients may still need to wear glasses after the procedure.
If you have private health insurance and require cataract surgery, it’s important to know that the procedure is typically performed one eye at a time and usually involves the placement of a monofocal lens, similar to those provided in NHS treatments.
Insurance patients also have the option to upgrade to enhanced or premium lenses. This can be particularly advantageous for individuals with astigmatism or for those looking to improve their intermediate and near vision.
What is astigmatism and why does it matter?
Astigmatism causes two focal points of light to focus on the retina, causing ghosting or blurring of vision, in between 30-60% of the population.


It can usually be corrected by glasses or contact lenses. Alternatively we can permanently apply the astigmatism correction to the intraocular lens we insert into your eye. This may avoid the need for glasses or contact lenses, offering you more freedom. We offer astigmatism correction as standard.*
* Insurance companies do not cover the cost of astigmatism correcting intraocular lenses. An additional charge will apply.
Cataract Surgery FAQ's
How do I know when I need cataract surgery?
A cataract is the clouding of your natural crystalline lens inside your eye. This transformation happens over a lifetime. Without you realising, your appreciation of colours gradually changes with the world developing a sepia tone. As they progress, cataracts cause increasingly blurred vision. You may also notice that your night vision deteriorates with glare, halos, and starbursts around lights.
A cataract doesn't ripen - this is a construct developed to delay and rationalise the need for surgery. As a cataract develops, it speeds changes in your glasses prescription, meaning you will likely need to change your glasses more frequently.
We all have different occupations, interests and visual needs. Ultimately, the time for surgery is when the cataract impairs your quality of life.
Is cataract surgery safe?
Cataract surgery is one of the most common and safest procedures performed. Millions are performed each year. No surgery is without risk, but the risk of causing you to lose your eyesight is less than 1 in 10,000.
How do I choose a surgeon?
In the UK, we are very fortunate that cataract surgery is integral to an ophthalmologist's training. However, similar to any profession, a range of abilities exist. A good guide is asking about the number of procedures the surgeon performs per annum and their complication rates. Ideally, choose a surgeon where this is their bread and butter, performing routine, higher volume cataract procedures (>~500 per annum).
If you wish to reduce your dependence on contact lenses or glasses following the procedure, choose a Refractive trained surgeon. Refractive surgery is not included in UK training and requires further years of specialist training. Choose a surgeon who has undertaken this additional training and has CertLRS qualification. For further information on lens choices click.
Other tools to decide on your surgeon include online reviews, speaking to colleagues and friends, and discussing with your GP or Optometrist. Additionally, all UK surgeons working in the NHS have their NHS safety data published; https://nodaudit.org.uk
Ultimately you want somebody with whom you can trust and build a rapport.
Are there different types of cataract?
We describe cataracts by their appearance, splitting them into;
Nuclear - when the centre of the lens is affected - these changes are slow and develop over decades.
Cortical - these changes are at the edge of the lens and typically cause spokes similar to the wheel of a bike. The spoke changes usually start at the outside, moving in with time. They affect the vision increasingly as they move more centrally.
Posterior sub-capsular - when the back of the lens is affected. These grow more quickly and may occur at a younger age. This type affects the vision more profoundly and usually needs surgery more quickly. These can develop following trauma or after using certain medications, such as steroids.
It is common to have more than one of these at a time.
Does the maturity (how advanced) or type of cataract affect the surgery?
The type of cataract influences how it affects your vision and its development speed but does not make a difference surgically. There are many different techniques used to remove cataracts. The surgeon must have sufficient experience to adapt during each procedure, optimising the technique for your eye.
Denser, more advanced cataracts typically require more ultrasound energy to remove. This can delay healing and make the surgery more technically challenging if very mature. Mr Darcy has years of experience with thousands of cataract procedures. Other surgeons often refer him the technically more complex cases.
How does private cataract surgery differ from NHS?
We are all fortunate to have the NHS. During times of emergency, the NHS typically provides a quality of care paralleled by the best healthcare systems in the world.
The volume of work can place increased challenges on elective outpatients and surgery, with varying waiting times.
All private providers are also not equal, and doing homework is essential.
In general terms, the differences you should expect from private cataract surgery are;
- Ability to choose your surgeon.
- Consultant surgeon
- Greater convenience with shorter waiting times
- Full range of intraocular lenses - NHS trusts carry single mono-focal lens banks as a one-type must fit all patients model.
- Opportunity to achieve greater spectacle independence
- Astigmatism correction - a limited number of NHS trusts offer toric intraocular lenses, which are only allowable above pre-determined levels. Privately astigmatism should be corrected as standard. We would strongly suggest checking this with your chosen private provider.
- Enhanced and premium cataract surgery offers the ability to reduce or eliminate your need for glasses at all distances using specialist intraocular lenses.
Should I feel guilty going privately and not using the NHS?
This is a common question asked and something unique to the UK. The simple answer is no. Alleviating pressure from the NHS frees money and finite resources for the NHS to concentrate on the emergency and cancer care we all occasionally need. This sense of guilt is something unique to the UK and the NHS. Other countries around the world incentivise or even penalise people via increased taxation to reduce the burden on their public healthcare systems.
What else should I consider before cataract surgery?
Prior to treatment, you will have had a thorough consultation with Mr Darcy and opportunity to get all your questions answered. He will send you a detailed consent form for you to review and discuss any points pre treatment and useful instructions for treatment and immediate recovery.
10-20% of lens patients can experience posterior capsule opacification (PCO), which means the casing can become cloudy and the clarity of vision is reduced. This can be effectively treated with a YAG laser treatment, performed by your doctor in clinic. Please note this procedure is not included within your initial surgery fee.
