Driving After Cataract Surgery UK 2026: DVLA Rules & Timeline

You must not drive on the day of cataract surgery. Most UK patients can resume driving 24 to 48 hours after routine first-eye surgery once they can read a number plate at 20 metres in good daylight (the DVLA Group 1 visual standard). HGV and PCV (Group 2) drivers must meet stricter binocular acuity and visual-field standards and should wait until the post-operative review.

Fast answer: when can I drive after cataract surgery?

For a routine first-eye cataract operation, most UK 2026 patients are back to driving within 24 to 48 hours, as soon as they meet the DVLA Group 1 standard — reading a number plate at 20 metres in good daylight, with both eyes open and any glasses or contact lenses you normally wear. You should never drive on the day of surgery because of the dilating drops, residual blur and the after-effects of the local anaesthetic. If you only had one eye done and the other eye still sees well, you can usually drive as soon as the combined vision meets the standard and feels comfortable.

Honest one-liner: the legal test is the number plate, not a fixed number of days. If you can read a plate at 20 metres in daylight and the eye feels comfortable, you can drive — for most people that is the day after surgery.

The DVLA Group 1 visual standard explained

The legal standard for ordinary car and motorcycle (Group 1) drivers in the UK has two parts, and you must meet both with both eyes open, wearing any corrective lenses you normally use:

Number-plate test — read a current-style number plate at 20 metres (about 5 car lengths) in good daylight.
Visual acuity — at least Snellen 6/12 (decimal 0.5) measured on the standard chart, using both eyes together or your better eye if you only have sight in one.
Visual field — an adequate field of vision; cataract alone does not usually reduce the field, but co-existing glaucoma can.

If your best-corrected vision is worse than 6/12 you do not meet the standard and must not drive — that is also a recognised reason to be fast-tracked for cataract surgery on the NHS or to go private. After successful cataract surgery, vision in the operated eye is usually well above this threshold within a day or two.

When you can drive again — a practical timeline

Day 0 (surgery day) — do not drive

Dilating drops, the local anaesthetic and post-operative blur mean you must not drive home or anywhere else. Arrange a lift, taxi or public transport. Vision is typically blurry, watery and a little bright on the day.

Day 1–2 — most people resume

Once the dilation has worn off and you can read a number plate at 20 metres in daylight, you can drive. Many patients are comfortable driving the day after surgery. Start with short, familiar daytime journeys before longer or night driving.

Between first and second eye — check comfort

If your two eyes now have very different prescriptions (anisometropia) before the second eye is done, vision can feel unbalanced. Drive only if the combined vision meets the standard and feels comfortable; some people prefer to wait until the second eye is treated.

Weeks 4–6 — final prescription

Glare and halos around lights at night settle as the eye stabilises over 4 to 6 weeks. Your final spectacle prescription is confirmed at the end-of-treatment review, after which night driving is usually back to normal.

HGV and PCV (Group 2) drivers

If you hold a Group 2 licence (lorries over 3.5 t, buses, coaches), the standards are stricter and you should not assume the 24–48 hour timeline applies. Group 2 drivers must meet:

Visual acuity of at least 6/7.5 in the better eye and 6/60 in the worse eye (with glasses or contact lenses).
An uninterrupted horizontal visual field of at least 160 degrees.
No significant defect within the central 30 degrees.

Wait until your post-operative review confirms you meet these standards before returning to professional driving, and follow any advice from your operating consultant. Both eyes are often treated before a Group 2 driver returns to the wheel.

Need cataract surgery before your vision affects your licence? A consultant assessment includes biometry, a full eye examination and IOL options counselling, with same-week appointments.

Do I need to tell the DVLA?

For routine cataract surgery you do not need to notify the DVLA, provided you still meet the visual standard afterwards (which almost everyone does). You must tell the DVLA if:

Your vision in both eyes remains below the standard even with glasses or contact lenses.
You have a visual-field defect (for example from co-existing glaucoma).
You have double vision that is not corrected.
You are a Group 2 driver and your vision no longer meets the higher professional standard.

It is your legal responsibility to be sure you meet the standard before driving. If in doubt, ask your optometrist to measure your acuity, or check at your post-operative review.

Night driving, glare and halos

It is common to notice some glare, starbursts or halos around bright lights — especially oncoming headlights — in the first few weeks after cataract surgery. This usually settles as the eye stabilises over 4 to 6 weeks. Patients who choose a multifocal or trifocal intraocular lens (IOL) may notice more night-time halos than those with a monofocal or EDOF lens; for most people these become much less noticeable as the brain adapts. If glare is severe or worsening rather than settling, mention it at your review.

Frequently asked questions

Can I drive home after cataract surgery?

No. You must not drive on the day of cataract surgery. The dilating drops, the local anaesthetic and the residual blur all impair your vision and reaction on the day. Arrange a lift, taxi or public transport to get home, and plan not to drive until at least the next day, once you can read a number plate at 20 metres in good daylight.

How soon can I drive after cataract surgery in the UK?

Most UK patients can drive 24 to 48 hours after routine first-eye cataract surgery, as soon as they meet the DVLA Group 1 standard: reading a number plate at 20 metres in good daylight with both eyes open and any glasses or contact lenses you normally wear. The legal test is the number plate and a visual acuity of at least Snellen 6/12, not a fixed number of days.

What is the DVLA eyesight standard for driving?

For Group 1 (car and motorcycle) drivers you must be able to read a current-style number plate at 20 metres in good daylight and have a visual acuity of at least Snellen 6/12 (decimal 0.5) with both eyes open, wearing any glasses or contact lenses you normally use, plus an adequate visual field. Group 2 (HGV/PCV) drivers must meet stricter standards of at least 6/7.5 in the better eye and 6/60 in the worse eye, with a horizontal field of at least 160 degrees.

Do I need to tell the DVLA about cataract surgery?

For routine cataract surgery you do not need to notify the DVLA, as long as you still meet the visual standard afterwards. You must tell the DVLA if your vision stays below the standard even with correction, if you have a visual-field defect (for example from glaucoma), if you have uncorrected double vision, or if you are a Group 2 driver who no longer meets the higher professional standard.

Can I drive between my first and second eye cataract operations?

Often yes, provided your combined vision still meets the DVLA standard and feels comfortable. If the two eyes now have very different prescriptions (anisometropia) before the second eye is treated, vision can feel unbalanced and some people prefer to wait until the second eye is done. Drive only if you can read a number plate at 20 metres and feel safe.

Why do I see glare and halos at night after cataract surgery?

Some glare, starbursts or halos around bright lights are common in the first few weeks after cataract surgery and usually settle as the eye stabilises over 4 to 6 weeks. Multifocal and trifocal intraocular lenses can produce more night-time halos than monofocal or EDOF lenses, though most patients adapt. If glare is severe or worsening rather than improving, raise it at your post-operative review.

Can I drive at night straight after cataract surgery?

It is best to start with short, familiar daytime journeys before driving at night. Early glare and halos around headlights are common and settle over the first few weeks. Once your eye feels comfortable, you meet the number-plate standard and night-time glare has settled, night driving is usually back to normal — for most patients within a few weeks.

What if my vision is below the driving standard before surgery?

If your best-corrected vision is worse than Snellen 6/12 you do not meet the DVLA Group 1 standard and must not drive. This is also a recognised reason to be fast-tracked for cataract surgery on the NHS or to choose private surgery, which can be arranged within one to two weeks. After successful surgery, vision in the operated eye is usually well above the standard within a day or two.
