Cataract Surgery

Your vision is important : Choose the best cataract surgery service in Shropshire !

Cataracts can take away one of the most important aspects of our lives away from us, that is our vision. Thankfully, cataract specialists at Paragon Clinic, Shrewsbury can help you see again with the help of modern medicine. Our cataract surgery consultants with decades of experience can help you see again. Through the use of the most advanced technology available today, we have completed thousands of successful cataract surgeries. Our cataract surgeons specialise in dealing with complex cases, ensuring your complete 20/20 vision, regardless of severity.

What Happens During Cataract Surgery?

Our experienced cataract specialists employ local anaesthesia near your eye to numb the organ. The surgeon creates a small cut in the eye (usually 2.5mm) using microscopic precision to remove the cloudy lens. 

We use the most advanced equipment to assist in the procedure, ensuring successful and comfortable surgery. Our cataract surgeons will then replace the cloudy lens with an artificial lens called an intraocular lens, or IOL. We use premium monofocal IOL as our standard lens. We will discuss them later.

Symptoms Of Cataract

According to a study, every 1 in 2 people above the age of 65 is suffering from cataracts. Cataracts can lead to several quality-of-life downgrades; hence identifying their symptoms at an early stage is crucial. Here are some common symptoms of cataracts that you should be aware of:

  • Cloudy or blurry vision,
  • Sensitivity to light and glare,
  • Impaired night vision,
  • You see a halo around bright lights,
  • The colours start to look faded.

If you notice any symptoms of Cataracts or even if you don’t; visit us for a free initial consultation. This is a detailed eye examination using state-of-the-art scans and measurements. Your consultant will discuss all aspects of eye health and determine if cataract surgery is the right choice. You will also be told of all options available to give you the best outcome after surgery, many of which are not available on the NHS.

Why free consultation ?

Now you might be wondering why we are offering the initial consultation for free. Well, certain things in life are more important than money and your vision is definitely on that list. Additionally, we help patients be aware of the surgery or lens implant choices that are not available on the NHS. This is why we decided to offer a free, no-obligation consultation.

Why Should You Opt For Cataract Surgery?

Vision is one of the most important parts of our lives. Cataract is a very common yet serious disease that affects this very part of our lives. Thankfully cataract surgery can help you completely recover your vision and lead a normal life once again. 

Cataract surgery is one of the most successful operations in the healthcare sector, ensuring your safety. Cataract surgery may also correct your seeing capabilities, removing any need to wear prescribed glasses.

Why do we think we are the best cataract surgery service in Shropshire ?

  • We only use “Premium Advanced Technology” lens implants.
  • All patients electing for a monofocal IOL will get a premium monofocal IOL as standard. This special lens gives excellent distance and more intermediate vision, with fewer aberrations than lens implants available on the NHS. Even private hospitals offering cataract surgery do not offer this as standard and routinely use the same lens implant as in the NHS.
  • Our cataract eye surgeons have expertise in implanting all types of IOLs including astigmatism correcting and multifocal IOLs. At many cataract surgery private hospitals, only a minority of surgeons offer this service, and your choice of lens implant could be limited.

Our expertise

  • Experienced surgeons who perform hundreds of cataract-removal surgeries each year, including complex surgeries.
  • Timely surgery – No waiting to see better again.
  • Advanced technology that can correct astigmatism along with removing the cataract, as well as a state-of-the-art measuring and scanning system to perform cataract surgeries that is extremely precise and individualized to give you the best vision possible after surgery.
  • The most advanced options for replacement lenses to improve your vision after surgery

Why Choose Paragon Clinic At Shrewsbury For Your Cataract Surgery Or Refractive Lens Surgery?

Cataract and Lens surgery is a once-in-a-lifetime opportunity to change the way you see forever. Don’t take this lightly. Please make an informed decision about your eyes. 

While several hospitals and clinics provide cataract surgery and refractive lens surgery, they only offer basic cataract surgery. Traditionally, the surgery only involves taking your cataract or lens out and replacing it with a lens implant. 

These traditional artificial lenses were fixed for one distance, requiring most patients to need glasses after cataract surgery. However, with premium lens implant technology offered by Paragon Clinic at Shrewsbury, it offers a full range of vision, without the use of glasses. So, in addition to getting rid of your cataract, you could also improve your spectacle prescription.

At Paragon Clinic, in addition to the conventional, basic biometry calculations, our surgeon uses four extra eye scan calculations called aberrometry, pupillometry, wavefront analysis and angle kappa measurements to ensure the best-fitting lens implant is chosen for your eye.  We believe that it is only by taking these additional factors into account, we can achieve the maximum confidence in selecting the best lens implant for your eye.

How is Paragon Clinic different to other private cataract providers?

The range of lens implant choices, and the expertise of our surgeons makes us stand out from the crowd.

There are many hospitals and clinics that provide cataract surgery and refractive lens surgery, and cataract surgery is also available on the NHS.

  • The lens implant: We bring the most advanced technology to select the best intraocular lens implant and customising it for you.
  • The surgeon: Your surgeon will have expertise in implanting the entire range of lens implants – from premium monofocals to extended depth of focus IOLs to multifocal and astigmatism correcting Toric IOLs.

Is Paragon Clinic different to other private hospitals when it comes to selecting my lens implant?


    Customising to an individual patient On the NHS, and in almost all private hospitals, the lens implant is selected by a test called ‘Biometry’. At Paragon Clinic, in addition to the state-of-the-art Biometry, we also carry out more advanced tests to customise and personalise the lens implant specially for you.

    If your private hospital does not offer these tests, and if your consultant does not discuss the results of these tests prior to selecting your lens implant, you may be short changed! And if you are told these tests are not needed (because they do not have the high-tech equipment needed), be even more wary!

    These tests are not provided on the NHS for cataract surgery.

  • Wavefront analysis: Measures higher order optical aberrations that can influence the type of lens implant suitable for you.
  • Corneal Topography: Measures the total curvature of the cornea, reflecting the amount and type of astigmatism that should be corrected at the time of surgery. They rely on a small 3mm central zone and would make presumptions about the entire cornea based on this.
  • Pupillometry: Measuring the pupil in bright and dim light can have a profound impact on the choice of lens implant.
  • Angle Kappa measurements: This measures the centration of your lens implant in relation to your pupils.

Paragon Clinic offers Wavefront Analysis, Corneal Topography, Pupillometry and Angle Kappa measurements as standard for all our patients as part of your free cataract or lens surgery consultation. Your consultant will discuss this with you as part of the decision making in selecting the most appropriate lens implant for you.

If you have not been offered the above tests as part of your cataract assessment, you may not have received a bespoke pre-operative assessment to customise your lens implant.

We are proud to offer the most advanced technology to get the best clinical outcomes.

Always ask your cataract consultant or hospital if they do the following tests in addition to the standard biometry measurements

Angle kappa measurements
Wavefront analysis
Corneal topography

Choosing your Surgeon – Not all cataract surgeons are the same

It may come as a surprise to you that less than 10% of all cataract surgeons in the UK use premium lenses. And of those, very few can be considered experts in selecting the best lens for you as most do not have access to the modern high-tech equipment that we have at paragon.

In most private hospitals, you are more likely to see one of the 90% of surgeons who will only offer you a standard monofocal IOL.

The question to ask about your surgeon:

  • Do you regularly implant advanced technology IOLs like Multifocal IOLs, Astigmatism correcting Toric IOLs, Extended Depth of Focus (EDOF) IOLs etc?
  • If the answer is “NO” (more than 90% of UK cataract surgeons) then you are more likely to receive the standard NHS lens even if you are paying privately.

So, make sure you do your research before selecting your surgeon.

More about your lens options

Until recently all artificial intraocular lens implants (IOL) were fixed for one distance; requiring most patients to need glasses after cataract surgery. Today, there are many different lens implant options available that provide a fuller range of vision; improving your vision at near, intermediate and distance, much like the lens you were born with.   Most patients who choose these “Premium Vision” lenses do so because they prefer a fuller range of vision without the use of glasses the majority of their day. So as well as improving your vision cataract surgery is an opportunity to change your spectacle prescription and how you use or need glasses afterwards.

Unfortunately these advanced lens implants are not available on the NHS, and not all surgeons in many private hospitals specialise in implanting these lenses. Paragon Clinic offers ALL lens options to ALL our patients based on clinical need following a free consultation, and detailed eye examinations and measurements of your eye.

It is worth thinking carefully about the sort of tasks you use your eyes for and how well spectacles have worked for you up until now. When we use our eyes we can divide tasks into three broad categories:

  • Far vision: this covers tasks and activities beyond 3 metres or so and includes driving, getting around generally, recognising friends across the street, most sporting activities and watching TV.
  • Intermediate vision: is used for tasks at about 1 to 2 metres. This includes most social interaction, computer work, reading music and some sports.
  • Near vision: this is for activities performed at 30 to 50 centimetres such as reading a book, using a laptop or tablet computer and many handicrafts.

Most people spend the majority of their time looking at things in the middle distance and beyond (far vision), and comparatively little time reading or doing other near or intermediate vision tasks. In addition, most people, by the time they need cataract surgery, have started to need to wear spectacles for reading and using the computer even if they don’t need them for distance.

One lens implant may suit you better than another depending on your personal balance of how you use your eyes at the various distances. This information summarises the main lens implant choices that are available to you, but it is important to remember that the choice is always a compromise between different aspects of vision – at the moment there is no lens implant available that gives every person perfect vision at all distances under all circumstances.

Monofocal Lens Implants

Monofocal lens implants are “fixed focus” lens implants that give good vision at one particular distance. They are the commonest type of lens that people choose for cataract surgery because they give predictable results and high quality vision afterwards. Monofocal lens implants give good vision at one particular distance, but objects closer or further away will be increasingly out of focus and you will need put spectacles on to see clearly at those other distances.

Depending on how you use your eyes you can choose where to set the focal point, and there are several options:

At Paragon Clinic, you can benefit from the latest advanced technology Premium Monofocal IOL, the Eyehance IOL from Johnson & Johnson or the Vivity IOL by Alcon.

Monofocal lenses for far vision in both eyes:

Implanting a monofocal lens optimised for far vision in both eyes will provide good vision without spectacles for driving and so on but, because the lens is fixed focus, you will almost certainly need to wear glasses to read and use a computer (i.e. near and intermediate vision). Despite not “needing” spectacles for distance some people choose to wear bifocal or multifocal glasses after surgery simply for convenience – the top section of the lens simply has no optical power.

If you are accustomed to using reading spectacles or bifocals/multifocals and you are happy to continue doing so after your cataract surgery, then using monofocal lens implants for far vision is probably the most predictable option for you. This is the commonest choice that people having cataract surgery make.

Monofocal lenses for near vision in both eyes:

Another potentially useful, although less common, option is to put monofocal lenses optimised for near vision in both eyes. This means that you would be able to read and perform other near vision tasks without glasses, but you almost certainly would require spectacles for distance vision. Again you could choose to have bifocal or multifocal spectacles, but you may not need to wear them around the house or when reading.

Some people have just the “right” amount of short-sightedness so that they can read and perform other near vision tasks without the need for glasses, although they usually need spectacles to see well in the distance. If you are in this group monofocal lens implants for near vision in both eyes is a good choice because it can be difficult to learn to use reading glasses if you are not accustomed to using them. On the other hand if you do tasks or activities that rely on good distance vision, especially where glasses are a nuisance (e.g. sailing, bush-walking in the rain, swimming, diving etc), or if you simply don’t like wearing glasses, then option 1 is still a very good choice.

Monofocal lenses for monovision:

Because most people have two eyes we can use a different monofocal lens implant in each eye to give vision at different distances. This is called monovision and the main advantage is that it can reduce your need for spectacles. Some contact lens wearers may have already experienced this with one eye set up for distance vision and one eye for reading.

With monovision the brain chooses which eye to use depending on what you are giving attention to, and there is no conscious effort when switching from distance to near viewing. When you compare the two eyes, say when looking in the distance, there will be a noticeable difference between them, but remember that we’re giving each eye a different job and most people keep both eyes open most of the time!

There are two main types of monovision:

“Full” monovision: is where we set up one eye to see well for far vision and the other for near. You would have a distance vision eye and a reading vision eye, and full monovision gives a high degree of spectacle independence. The main drawback is that some people find that they can’t get used to the asymmetry between the eyes (known as anisometropia). If this happens then spectacle correction of the imbalance is often also troublesome and the only solution is another operation. Full monovision lens implants work best for people who have had a successful experience of it with contact lenses.

“Mini” monovision: is where we set up one eye for far vision and the other for intermediate tasks. This is useful for things like driving (the distance eye sees down the road and the intermediate eye the dashboard), computer work, social interactions and some sports. With mini-monovision the difference between the eyes is much less, so the risk of troublesome anisometropia is reduced, and usually can be helped with spectacles if necessary. With mini-monovision you will probably still need glasses for reading, especially small print or in low light.

With monovision, especially full monovision, it is preferable to set up your dominant eye for distance and your non-dominant eye for near or intermediate. Once cataracts have developed it can be difficult to work out which is your dominant eye, but your optometrist may have assessed this previously, or you may know from your own experience, e.g. when shooting (either a camera or gun!). If we can’t confidently work out which is your dominant eye then full monovision should definitely be avoided. With mini-monovision it is usually less of a problem but occasionally if we set your eyes up the wrong way round (known as crossed-dominance) you might find the vision uncomfortable and need to either have spectacle correction or further surgery.

The final potential disadvantage of monovision is that it can impair depth perception, because the eyes are set at different focal lengths. For most people this is not a  noticeable problem, but if you do any tasks or hobbies that require fine judgement of depth or distance (e.g. fine needlework/embroidery, watch-making, soldering etc) then you could find these activities more difficult afterwards.

Extended Depth of Focus Lens Implants

As described above a monofocal lens implant has its focus at a fixed point, but other lens implant designs give more range of vision. The “Vivity” lens implant by Alcon is an extended depth of focus lens implant and is designed to give sharp vision over a continuous range of distances, usually from about arm’s length out to far distance. Because everything is in focus over this wide range of distances you will probably not need glasses at all for the majority of day-to-day tasks.

With the Alcon Vivity lens most people have some ability to read at near as well, although this is usually limited to “spot reading” (e.g. checking a packet in the supermarket, reading a menu etc.), and may require good light. About 30% of people do not need reading glasses at all, but most need some help with prolonged or more demanding reading situations, although these may just be off-the-shelf magnifying reading glasses.

Multifocal Intraocular Lenses (Trifocal)

Multifocal Intraocular lenses are a good option for a select group of patients undergoing cataract surgery. The general principle with intraocular lens selection is the right type of lens for the right type of eye and patient. Multifocal intraocular lenses are not suitable for everyone.

At Paragon Clinic, we use the most advanced multifocal IOL – the Panoptix Trifocal by Alcon or the Synergy trifocal by Johnson & Johnson that will give you good distance, intermediate and near vision. This is one of the most expensive premium lenses in the market which we offer as an affordable package.

As their name suggests multifocal intraocular lenses provide the ability to see at varying focuses.  This is typically for near such as reading a book, middle distance such as a computer screen and far distance such as driving. The benefits of being spectacle independent are considerable in some, but not all patients. Not reaching for reading glasses has its potential advantages.

Haloes and reduced contrast sensitivity can be potential side effects of multifocal IOLs, although they are a lot less with the latest generation of IOLs we use at Paragon Clinic. Pre-operative evaluation and selection of the right patient to receive a multifocal intraocular lens is paramount to gaining a good outcome. Book a free consultation today to find out if a multifocal IOL is best for you.

Important information for all lens implants

Irrespective of which lens implant you choose for your cataract operations there is always an element of unpredictability in the outcome of the surgery. This is because people’s eyes are subtly different and we cannot measure all of the variation between individuals that might affect the outcome. Furthermore healing or scarring after an operation can also vary and give unexpected results. Overall we get between 90 and 95% of people close to what we intend, but this does mean that, despite our best efforts and intentions, some people do still need spectacles for the best possible vision. In a small number of cases further surgery or laser treatment may be required to improve the outcome.

As for any operation cataract surgery carries a small risk of something going wrong during the procedure, and in some cases this may mean that it is not possible to implant your first choice lens implant. If this happens it may be necessary for the surgeon to choose the “next best” option during the operation, or to leave the eye without a lens implant so that an alternative can be chosen in consultation with you and implanted at a further operation.

The process

  • Free Initial consultation

    You will be seen by a team of consultant ophthalmologist specialising in Cataract and Refractive surgery, and a specialist Nurse consultant. At this visit, we will take a detailed history, examine your eyes, take several measurements of the eyes, check vision and dilate your pupils for a more detailed examination of the cataract and the retina. You will have various high tech scans like biometry, corneal topography, OCT etc. Your consultant will discuss all aspects of eye health with you and examine your eyes to determine if cataract surgery is the right choice.

  • Surgery

    You are awake throughout the procedure medications. Drops are used to numb the eye surface for the surgery. The incision is so tiny that it doesn’t need any sutures; it is self-sealing. The procedure is painless, and most patients say it is better than going to their dentist!

  • Next-day

    We will ring you to check that all is well.

  • Two-weeks later

    Final post-operative visit. If having cataract surgery on the second eye, the process begins again.

  • Four-weeks later

    You see your optician to sort out new glasses, and also for a final post-operative assessment.


Are cataracts treatable?

Cataracts are treatable via surgery. Leaving cataracts untreated could potentially lead to blindness; however, cataract surgery can get rid of cataracts and correct your vision problems.

Can I prevent cataracts?

Unfortunately, if a cataract has already started to grow on your eye lens, there is no way of stopping it from growing further. It can only be treated through cataract surgery. Regular eye check-ups and a healthy lifestyle can reduce the chances of developing a cataract.

What are the benefits of cataract surgery?

Cataract surgery can reverse all the negative symptoms of cataracts and offer several improvements to your quality of life. Surgery can restore, clear vision, night vision, colour saturation, distance gauging abilities, and much more.

How long does it take to recover from cataract surgery?

Recovery duration from cataract surgery can change from person to person. While people can go back to their daily normal lives within 1-3 days of the surgery, many patients claim their vision fully stabilises after 4 to 6 weeks.

How does cataract surgery work?

A patient suffering from cataracts develops a cloudy screen on their eye lens, causing vision problems. A surgeon performing cataract removal surgery removes the cloudy lens and replaces it with an intraocular lens (IOL). The surgery is performed under local anaesthesia and lasts about 1 hour.
