How much you read, drive at night, or work on screens, all of it changes which lens suits you.
Cataract lens choice · Himayat Nagar
Which lens goes in after your cataract, monofocal or premium?
When a cataract is removed, it is replaced with an artificial lens that stays in the eye, and you choose what kind. That choice affects how much you rely on glasses afterwards. No single lens suits everyone. This page compares monofocal, EDOF and multifocal lenses.

Side by side
How the lens choices compare.
A like-for-like look at the three vision profiles. No single lens suits everyone. Each suits a different life.
| Monofocal | EDOF | Multifocal | |
|---|---|---|---|
| What you'll see | Focus at one distance (usually far) | A continuous range, far to intermediate | Far, intermediate and near |
| Glasses afterwards | Readers needed for near | Glasses usually not needed for far/intermediate; readers for fine print | Least need for glasses, varies by person |
| Night vision | Least halo and glare | Few halos | Some glare/halos possible |
| May suit you if you | Want distance vision and don't mind readers | Want a natural range with minimal night effects | Want the least dependence on glasses |
| Astigmatism | Toric version available | Toric version available | Toric version available |
| Cost / insurance | Standard, often insurance-covered | Premium upgrade, usually out-of-pocket | Premium upgrade, usually out-of-pocket |

Choosing a lens
How the lens is chosen.
The lens decision is about your life as much as your eyes, so we start with how you actually use your vision.
Patient guide
Choosing a lens: what to know before you decide.
A lens implant is chosen once and usually stays for life, so it helps to know what each lens asks of you as well as what it offers.
Who it is for
- Anyone planning cataract surgery. Every cataract operation needs a lens implant, so this choice applies to all patients.
- The choice depends on your eye measurements, the health of your retina, and how you use your eyes day to day.
How the choice is made
- Your daily life.Reading, screens, night driving, work and hobbies are discussed, because each lens favours different distances.
- Measurements.Optical biometry, corneal topography and a macular OCT scan are done.
- What your eye allows.You are told which lens types are suitable for your eye and which are not advised.
- Your decision.You choose among the suitable options. You can take the information home before deciding.
Which tests are done, and why
- Optical biometry.Gives the eye length and corneal curve used to calculate lens power.
- Corneal topography.Shows the amount and regularity of astigmatism. Regular astigmatism can be corrected with a toric lens.
- OCT of the macula.Multifocal and extended-depth lenses divide light between distances, so they are generally not advised when the macula is not healthy.
- Eye pressure and optic nerve check.Significant glaucoma also affects which lenses are suitable.
Limits of each lens
- Monofocal lens: focuses at one distance. Glasses are usually needed for the other distances, most often for reading.
- Toric lens: corrects regular astigmatism. A toric lens can rotate after surgery, and occasionally needs to be repositioned.
- Multifocal and extended-depth lenses: halos and glare around lights at night and some loss of contrast are known effects. Most people adapt over weeks to months, and a few do not.
- With any lens, some spectacle power can remain, and glasses may still be needed for certain tasks.
- A lens can be exchanged if necessary, but that is a second operation with its own risks.
- No lens restores the focusing ability of a young eye, and results vary from person to person.
The surgeon explains which of these apply to your eye before you choose.
What affects the cost
- The lens type selected is the main factor.
- Many insurance policies cover a standard monofocal lens and treat other lenses as an upgrade paid by the patient. This depends on your policy.
A written estimate is given after the consultation, once your eyes have been examined.
What to bring
- Your current glasses and earlier prescriptions.
- A note of what matters most to you: reading, computer work, night driving, sport or close hobbies.
- Records of any earlier laser vision correction such as LASIK, because it affects the lens power calculation.
- Earlier retina or glaucoma reports, if you have them.
How care is organised here
Assessment, procedure and follow-up as one plan.
Your assessment, your cataract surgery and follow-up visits are planned together, so the findings from your consultation carry through to the procedure and the reviews afterwards.
1
ConsultationExamination, measurements and time for your questions.
2
ProcedurePlanned from the measurements taken at your consultation.
3
Follow-upReview visits at set intervals, with written instructions.
At your consultation
What is discussed before any procedure.
- You meet the operating surgeon before the day of the procedure.
- The lens or treatment plan is discussed in relation to your eye and your daily needs.
- Risks, benefits and alternatives are explained, and results vary from person to person.
- You are told whom to contact after the procedure and when your reviews are due.

Common questions
Frequently asked questions
Which lens should I have after cataract surgery?
No single lens suits everyone. A monofocal focuses at one distance, with the fewest side effects. Premium lenses (EDOF and multifocal) reduce the need for glasses but can introduce some night-time glare. The suitable lens depends on your eyes, how you use them, and your budget.
Will I still need glasses after cataract surgery?
With a monofocal lens, yes, usually for reading or near work. With premium lenses, the need for glasses is usually less, though light readers are sometimes still needed for very fine print. Results vary from person to person. What to expect from each is explained at the consultation.
What are the downsides of premium (multifocal) lenses?
Mainly three: some people notice glare or halos around lights at night, especially early on (most people adapt over weeks to months, and a few do not); they cost more and are typically not covered by insurance; and not every eye is suited to them. You are told whether your eyes are suitable for them.
What is an EDOF lens?
EDOF stands for Extended Depth of Focus. Instead of separate near and far points like a multifocal, it is designed to give one continuous range of vision for distance and intermediate (dashboard, computer), with fewer night-time halos than a multifocal. Many people still use light readers for the smallest print.
Are premium lenses covered by insurance?
Usually the standard monofocal lens is covered and premium lenses (EDOF, multifocal, toric) are an out-of-pocket upgrade, but it depends on your policy. Send your insurer or TPA name on WhatsApp and we will confirm your specific cover before you decide.
Can my astigmatism be corrected at the same time?
Yes. A toric version of these lenses corrects astigmatism during the same cataract surgery, so less cylinder is usually needed in your glasses afterwards. Toric can be combined with monofocal or premium designs.
Is the lens permanent? Can it be changed later?
The lens is designed to stay for life, so the choice is made carefully before surgery, at the consultation. It can be exchanged if there is a problem, which is a further operation.
How do I decide which lens to choose?
We talk through how you use your eyes, how much you read, drive at night, or work on screens, and examine your eyes before a recommendation is made. Sometimes a monofocal is the suitable choice, and you are told so. You can contact the hospital on WhatsApp or by phone.
