The short answer

What to do first

Cataract surgery can make everyday sight clearer. Learn about referral, assessment, recovery, driving and warning signs across the UK.

Start here: Make a note of the tasks affected: reading labels, recognising faces, managing stairs, seeing in poor light or coping with glare. Cataracts often develop gradually and are not usually painful. A community optometrist can check vision and look for eye changes; depending on the local pathway, a GP may also assess or refer. If vision changes suddenly, there is severe pain or the eye is very red, do not assume this is an ordinary cataract. Seek urgent eye advice.

Do not wait: Contact the eye unit or NHS 111 urgently for severe pain, sudden loss of vision or increasing redness after surgery.

Scope of this guide

This guide helps you understand the options and questions to ask. It is not personal medical, legal or financial advice. Check the official sources for your nation and seek qualified help for high-stakes decisions.

If someone may be in immediate danger

Call 999 for a life-threatening emergency. For an urgent problem that is not clearly life-threatening, use the official NHS urgent-care route for the UK nation you are in. Have the address, symptoms, onset time, medicines and allergies ready.

Who this guide is for

People whose cloudy vision is affecting daily activities and who are considering an eye assessment or cataract operation.

Cataracts can make vision cloudy, colours faded and bright lights uncomfortable. If sight is affecting reading, cooking, walking or driving, an optometrist or GP can help assess what is happening and discuss referral. Surgery is a choice made with an eye specialist, based on how vision affects the person’s life and the likely benefits and risks. This guide describes the usual journey and practical preparation; the eye team’s individual instructions take priority.

What to do now

1. Notice what has changed and arrange an assessment

Make a note of the tasks affected: reading labels, recognising faces, managing stairs, seeing in poor light or coping with glare. Cataracts often develop gradually and are not usually painful. A community optometrist can check vision and look for eye changes; depending on the local pathway, a GP may also assess or refer. If vision changes suddenly, there is severe pain or the eye is very red, do not assume this is an ordinary cataract. Seek urgent eye advice.

2. Discuss whether surgery fits your priorities

An eye specialist will examine the eye and talk through whether a cataract is likely to explain the difficulty. Explain what the person wants to do more safely or comfortably, what other eye conditions they have and whether they manage alone at home. Surgery is usually considered when the effect on daily life matters to the person; a diagnosis by itself does not mean an operation must happen immediately. Ask about expected improvement, limits, possible complications, alternatives while waiting and what happens if you decide not to proceed. If the person has glaucoma, macular degeneration or another eye condition, ask how it could affect the expected result. It can help to write down whether the aim is safer mobility, easier reading or reduced glare, because the specialist can explain what the operation may realistically improve. Ask how long a decision can wait and who to contact if sight changes before the planned date.

3. Plan the day and the journey home

The hospital or clinic will explain preparation, consent, arrival time and whether usual medicines or food routines need any change. Do not change prescribed medicines unless the eye team or prescriber tells you to. Arrange a responsible person to accompany or collect the patient if the service advises it; do not drive yourself home after the procedure. Bring glasses, hearing aids, a medicines list, emergency contact details and any accessibility information. Ask for an interpreter, large print, extra time or support with mobility before the appointment.

4. Know what happens during the procedure

Cataract surgery removes the cloudy natural lens and places an artificial lens inside the eye. It is commonly done as a day procedure, usually with local anaesthetic, while the person is awake. Staff explain what to expect and how to keep still; tell them if anxiety, hearing, memory or movement makes instructions difficult. The exact method and lens discussion depend on the eye and the person’s needs. Ask the team to explain anything unclear before consenting, and make sure you know who to contact after leaving.

5. Follow the written recovery instructions

The eye may feel gritty or mildly uncomfortable, and vision can take time to settle. Use any prescribed drops exactly as directed and ask the clinic, GP or pharmacist if the instructions are confusing; do not guess or share drops. Avoid rubbing or pressing the eye. Follow the team’s guidance about washing, lifting, exercise, swimming and eye protection because advice can depend on the operation and recovery. Keep the discharge sheet beside the medicines and ask a family member to help with the routine only if the patient wants that support.

6. Restart activities and driving only when safe

Use the eye team’s advice about when to return to normal tasks. Reading, television and gentle movement may feel different as the operated eye settles; good lighting and help with stairs or cooking can reduce strain. Do not drive until vision meets the legal standard and the person can control the vehicle safely. DVLA rules apply in Great Britain and DVA rules in Northern Ireland; the driver remains responsible for notifying the relevant agency when required. Ask the optometrist or eye team to check concerns rather than relying on a fixed number of days.

Warning signs and checks

Common questions

How do I get referred for cataract surgery?

Start with an optometrist or GP and describe the effect on ordinary tasks, such as reading, recognising faces or walking safely. The referral route differs between local services and UK nations. An optometrist may refer directly in some pathways; elsewhere a GP or another clinician may coordinate it. The eye specialist assesses whether a cataract explains the problem and whether surgery is likely to help.

Is cataract surgery painful?

The operation is commonly carried out using local anaesthetic, so the person is awake but the eye is numbed. They may notice pressure, lights or movement rather than sharp pain. Tell the team if pain, anxiety or difficulty following instructions is a concern. Afterward, mild grittiness can occur, but severe pain, worsening redness or sudden sight loss needs urgent advice.

How long does it take to recover?

Recovery is not identical for everyone. Vision may begin to improve but can take time to settle, and other eye conditions may affect the result. Follow the hospital’s advice about drops, washing, lifting and activities rather than using a fixed timetable from someone else. Ask the eye unit when to arrange a review and what changes should prompt a call.

Can I drive after cataract surgery?

Do not drive home after the procedure, and do not resume driving until your vision meets the legal standard and you can drive safely. A set number of days does not suit every person. Ask the eye team or optometrist to assess concerns. DVLA applies in Great Britain and DVA in Northern Ireland; tell the relevant agency if the condition or vision means you must notify them.

What symptoms after surgery need urgent help?

Follow the discharge sheet and contact the eye unit or NHS 111 promptly for sudden loss or blurring of vision, severe pain or increasing redness. New flashes, a sudden increase in floaters or a dark curtain or shadow can also need urgent assessment. If you are unsure whether a change is expected, call the number supplied by the clinic instead of waiting for a routine appointment.

Differences across the UK

Eye-care pathways are organised separately in England, Scotland, Wales and Northern Ireland. In Northern Ireland, an optometrist or doctor may refer to an ophthalmologist; Wales and Scotland have community eye-care routes, while English local services can vary. The hospital team gives the specific surgical and aftercare instructions. Driving notification is through DVLA in Great Britain and DVA in Northern Ireland; eyesight standards still apply throughout the UK.

When to get urgent help

Contact the eye unit or NHS 111 urgently for severe pain, sudden loss of vision or increasing redness after surgery.
