Premium Lenses Explained: Monofocal, Toric, Multifocal and Extended Depth of Focus Lenses
If you're planning cataract surgery, one of the biggest decisions you'll make is choosing your new lens.
Many people don't realise they have options. During cataract surgery, the cloudy natural lens inside your eye is removed. It is replaced with a clear artificial lens called an intraocular lens (IOL).
The lens you choose can have a lasting effect on how you see after surgery. It can influence whether you need glasses for reading, driving or everyday tasks. It can also improve vision affected by astigmatism, which is when the front of the eye has an irregular shape that causes blurred vision.
There isn't one lens that is best for everyone. The right choice depends on your eyesight, your lifestyle and what you hope to achieve after surgery.
In this guide, we'll explain the four main types of lenses used during cataract surgery:
- Monofocal lenses
- Toric lenses
- Multifocal lenses
- Extended Depth of Focus (EDOF) lenses
We'll also discuss who each lens is suitable for, the advantages and trade-offs, and how your surgeon helps you choose the option that best suits your eyes.
Why your lens choice matters
Cataract surgery removes the cloudy lens that is affecting your vision.
Once that lens has been removed, it cannot be put back. The artificial lens that replaces it is designed to stay in your eye permanently. Because of this, it is worth taking time to understand your options.
Some lenses provide excellent distance vision but require reading glasses. Others reduce your dependence on glasses across several distances. Some are designed specifically for people with astigmatism.
Each option offers different benefits and compromises.
The goal is not to choose the most advanced lens. The goal is to choose the lens that best matches your visual needs.
What is a premium intraocular lens?
All cataract surgery involves replacing the cloudy lens with an artificial one.
A standard monofocal lens is often used in publicly funded healthcare systems and provides clear vision at one distance.
Premium intraocular lenses offer additional features that may improve your range of vision or correct other visual problems such as astigmatism.
These lenses are commonly chosen by people who want greater visual freedom after surgery.
For example, some people enjoy reading without glasses. Others spend long hours driving. Some play golf, cycle or travel frequently. Everyone has different priorities.
Premium lenses allow treatment to be tailored to the individual rather than using the same solution for everyone.
Monofocal lenses
Monofocal lenses are the most commonly implanted lenses worldwide.
They are designed to provide excellent vision at one distance.
Most people choose to have their distance vision corrected. This usually allows them to drive, watch television and recognise faces without glasses.
However, because the lens focuses at only one distance, reading glasses are normally needed for close work such as reading books, using a mobile phone or sewing.
Some people instead choose to focus for near vision and wear glasses for distance activities. Others choose a technique called monovision, where one eye is focused for distance and the other for near tasks. This is suitable for some patients but not everyone.
Who are monofocal lenses suitable for?
Monofocal lenses may be suitable if you:
- Don't mind wearing reading glasses
- Want excellent quality distance vision
- Prefer a simple, predictable visual outcome
- Frequently drive at night
- Want the lowest chance of seeing halos or glare
For many patients, monofocal lenses provide excellent visual quality and remain an outstanding choice.
Advantages of monofocal lenses
Monofocal lenses offer several important benefits.
They provide crisp, high-quality vision at the chosen distance.
They generally produce fewer visual side effects than multifocal lenses.
Night driving is often very comfortable because contrast sensitivity remains high.
Many patients also adapt quickly because the vision feels natural.
For these reasons, monofocal lenses continue to be recommended for many people, even when premium options are available.
Things to consider
The main limitation is that glasses are usually needed for at least one range of vision.
Most patients still require reading glasses after surgery.
If reducing dependence on glasses is one of your biggest goals, another lens option may be worth considering.
Toric lenses
Many people have astigmatism without realising it.
Astigmatism occurs when the front surface of the eye is shaped more like a rugby ball than a football. Instead of focusing light evenly, the eye creates blurred or distorted vision.
Simply removing the cataract does not correct astigmatism.
A toric lens is specially designed to correct this during cataract surgery.
The lens contains built-in astigmatism correction and is carefully aligned during surgery to match the shape of your eye.
This can significantly improve the sharpness of your vision after the procedure.
Who benefits from a toric lens?
A toric lens may be suitable if you have:
- Moderate or high astigmatism
- Blurred vision caused by the shape of your cornea
- A desire to reduce dependence on distance glasses
Toric technology can be combined with different types of lenses.
For example, you may have:
- A toric monofocal lens
- A toric multifocal lens
- A toric Extended Depth of Focus lens
This means your astigmatism can often be corrected while also achieving your preferred visual goals.
Advantages of toric lenses
For patients with astigmatism, toric lenses often provide much clearer vision than a standard lens.
Many people notice sharper distance vision and rely less on glasses for everyday activities.
Because the astigmatism has been corrected inside the eye, vision is often clearer than it would be with a standard lens alone.
Things to consider
Not everyone needs a toric lens.
Detailed measurements taken before surgery determine whether enough astigmatism is present for the lens to provide meaningful benefit.
The lens must also be positioned accurately during surgery. Modern imaging technology allows surgeons to align the lens with a very high level of precision.
Multifocal lenses
For many people, the biggest question before cataract surgery is, "Will I still need glasses?"
If reducing your dependence on glasses is one of your main goals, a multifocal lens may be worth considering.
Unlike a monofocal lens, which focuses at one distance, a multifocal lens is designed to provide useful vision at several distances. This may include distance, intermediate and near vision.
This means many people can carry out everyday activities such as driving, reading a menu, shopping or using a mobile phone with much less reliance on glasses.
It is important to remember that no lens can guarantee complete freedom from glasses. Some people may still choose to wear glasses for certain activities or in low-light conditions.
How do multifocal lenses work?
A multifocal lens contains several zones that focus light at different distances.
Your brain learns to use the image that is most in focus for the task you are performing.
This process is called neuroadaptation. Most people adjust well over the weeks following surgery, although it can take longer for some individuals.
Because everyone adapts differently, your surgeon will discuss whether this type of lens is likely to suit your expectations.
Who are multifocal lenses suitable for?
Multifocal lenses may suit people who:
- Want greater freedom from glasses
- Lead an active lifestyle
- Frequently switch between distance and near tasks
- Enjoy reading, travelling or hobbies without constantly changing glasses
- Understand that there are trade-offs
People who are highly motivated to reduce their dependence on spectacles are often the happiest with multifocal technology.
What are the advantages?
The biggest benefit is convenience.
Many people find they can perform most everyday activities without reaching for their glasses.
Reading a text message, shopping, dining out and recognising faces across the room often become easier without switching between different pairs of spectacles.
For many patients, this greater visual freedom improves confidence and quality of life.
What are the trade-offs?
Every lens design involves compromise.
Because multifocal lenses split light into different focal points, some people notice halos or rings around lights, particularly at night.
These visual effects are often most noticeable during the first few months after surgery and frequently become less noticeable as the brain adapts.
Some people also experience a slight reduction in contrast sensitivity. This means objects may appear a little less crisp in dim lighting than they would with a monofocal lens.
For this reason, multifocal lenses are not suitable for everyone.
People who do a great deal of night driving or who have certain eye conditions may achieve better results with another lens option.
Extended Depth of Focus (EDOF) lenses
Extended Depth of Focus lenses are a newer type of premium intraocular lens.
Rather than creating several separate focal points, they produce one continuous range of focus.
Think of it as stretching the area that stays in focus instead of creating multiple individual focus points.
This allows many patients to see clearly over a wider range of distances while producing fewer visual disturbances than traditional multifocal lenses.
What can EDOF lenses help with?
Most people with an EDOF lens enjoy excellent distance vision.
They also achieve very good intermediate vision for activities such as:
- Using a computer
- Cooking
- Shopping
- Looking at a car dashboard
- Playing golf
- Socialising
Many patients can also read larger print without glasses.
However, some people still need reading glasses for prolonged reading or very small print.
Who are EDOF lenses suitable for?
EDOF lenses are often an excellent choice for people who:
- Want less dependence on glasses
- Spend lots of time using computers
- Drive regularly
- Want fewer halos than are sometimes experienced with multifocal lenses
- Value high-quality distance vision
Many surgeons consider EDOF lenses a good middle ground between monofocal and multifocal technology.
Advantages of EDOF lenses
The main benefit is balance.
Patients often achieve excellent distance vision, strong intermediate vision and useful near vision.
Compared with traditional multifocal lenses, many patients experience fewer halos and better contrast sensitivity.
This makes EDOF technology particularly attractive for people who drive frequently or spend significant time outdoors.
Things to consider
EDOF lenses still involve compromise.
Although many people require glasses less often, they may still need them for prolonged reading or very fine detail.
For some patients, this small amount of spectacle use is an acceptable trade-off for maintaining excellent visual quality across most daily activities.
Which premium lens is right for you?
There is no single lens that is best for everyone.
Choosing the right lens depends on several factors.
Your eyesight
The shape of your eye, the health of your retina, whether you have glaucoma or macular degeneration, and the amount of astigmatism all influence which lenses are suitable.
Some premium lenses work exceptionally well in healthy eyes but may not be recommended if other eye conditions are present.
Your lifestyle
How you spend your day matters.
Someone who enjoys reading for several hours each day may have different priorities from someone who spends most of their time driving.
Your hobbies, occupation and daily routine all help guide the decision.
Your expectations
One of the most important conversations before surgery is understanding what you hope to achieve.
Some patients are happy wearing reading glasses if it means achieving the sharpest possible distance vision.
Others are prepared to accept small compromises in exchange for greater independence from spectacles.
Neither approach is right or wrong.
The goal is simply to match the lens to your priorities.
How your surgeon helps you choose
Choosing a premium lens should never feel overwhelming.
Before surgery, your eyes will be measured using highly accurate diagnostic equipment.
These measurements help determine:
- The strength of the lens
- Whether you have astigmatism
- Which premium technologies may be suitable
- Which lenses may not be recommended
Your surgeon will then discuss your lifestyle, expectations and visual goals.
Together, you can decide which option offers the greatest benefit for your individual circumstances.
The best choice is not always the newest or most expensive lens.
It is the lens that helps you live the life you want with the greatest confidence and comfort.
Frequently Asked Questions
Are premium lenses worth it?
The answer depends on your lifestyle and what you hope to achieve after cataract surgery.
For some people, a standard monofocal lens provides everything they need. They are happy wearing reading glasses and simply want clear distance vision.
Others want greater freedom from glasses. They enjoy travelling, playing sports, using digital devices or reading without constantly changing spectacles. In these cases, a premium lens may provide benefits that improve day-to-day life.
The right choice is a personal one. Your surgeon will help you understand whether the additional features of a premium lens are likely to benefit you.
Will I still need glasses after premium lens surgery?
Many patients become much less dependent on glasses after receiving a premium intraocular lens.
However, no lens can guarantee complete freedom from spectacles.
Some people may still choose to wear glasses for very small print, prolonged reading or certain tasks in poor lighting.
Your results will depend on the type of lens you choose, the health of your eyes and your visual expectations.
Your surgeon will explain what you can realistically expect before surgery.
Which premium lens provides the best vision?
There is no single "best" premium lens.
Each lens has been designed to solve different problems.
For example:
- Monofocal lenses provide excellent vision at one distance with very few visual side effects.
- Toric lenses correct astigmatism and can improve the sharpness of vision.
- Multifocal lenses provide the greatest range of vision and reduce dependence on glasses for many people.
- Extended Depth of Focus (EDOF) lenses offer excellent distance and intermediate vision with fewer visual disturbances than some multifocal designs.
The best lens is the one that matches your eyes and your lifestyle.
Can premium lenses correct astigmatism?
Yes.
If you have astigmatism, your surgeon may recommend a toric version of your chosen lens.
Toric lenses are available in monofocal, multifocal and Extended Depth of Focus designs.
Correcting astigmatism during cataract surgery often produces clearer vision and may reduce your need for glasses afterwards.
Are premium lenses permanent?
Yes.
The artificial lens placed during cataract surgery is designed to remain inside the eye for life.
Unlike the natural lens, it cannot develop another cataract.
Although some people develop a cloudy membrane behind the lens months or years after surgery, this is not another cataract. It is called posterior capsule opacification and can usually be treated quickly with a simple laser procedure.
Are premium lenses safe?
Premium intraocular lenses have been used successfully in cataract surgery for many years.
As with any medical device, every lens has advantages, limitations and potential risks.
Your surgeon will recommend only lenses that are suitable for your eyes and explain the benefits and possible trade-offs before you decide.
The aim is always to choose the option that offers the safest and most appropriate outcome for your individual circumstances.
How much do premium lenses cost?
Premium lenses generally cost more than standard monofocal lenses because they incorporate advanced optical technology and require additional planning before surgery.
The total cost varies depending on:
- The type of lens selected
- Whether astigmatism correction is required
- The complexity of your eyes
- The clinic providing your treatment
When comparing prices, it is important to understand what is included.
Some clinics include advanced diagnostic scans, follow-up appointments and premium technology within their package, while others may charge separately.
Rather than comparing prices alone, consider the experience of your surgeon, the technology being used and the level of care you will receive before, during and after your procedure.

Making the right decision
Choosing your lens is one of the most important decisions you will make during your cataract journey.
It is not about choosing the most expensive lens.
It is not about choosing the newest technology.
It is about choosing the option that fits your eyes, your lifestyle and your expectations.
Some people value the sharpest possible distance vision and are happy to wear reading glasses.
Others prefer greater independence from spectacles and are willing to accept some visual compromises to achieve that goal.
Neither decision is right or wrong.
The best result comes from understanding your options and making an informed choice with your surgeon.
Why personalised advice matters
No website can tell you which lens is right for your eyes.
Every person has a different prescription, different eye health and different visual priorities.
During your consultation, we perform detailed measurements of your eyes using advanced diagnostic technology. We also take time to understand how you use your vision every day.
Do you enjoy reading?
Do you spend hours on a computer?
Do you play golf, travel or enjoy other hobbies?
The answers to these questions are just as important as the measurements we take.
By combining advanced technology with personalised advice, we can recommend the lens that offers the greatest benefit for your individual needs.
