One of the most common questions patients ask before cataract surgery is also one of the simplest: “Will it hurt?”
For most people, cataract surgery is not painful. The eye is numbed before the operation, and patients may feel light, touch or a little pressure, but should not feel pain. It is completely normal, however, to feel anxious about any procedure involving the eye.
Knowing what to expect can make the experience feel much more manageable. Here is a clear guide to what usually happens before, during and after cataract surgery.

Cataract surgery is usually performed under local anaesthetic. Numbing eye drops are commonly used; in some circumstances, an injection around the eye or another form of anaesthetic may be recommended.
You will usually be awake, but the surgical team will talk you through what is happening and make sure you are comfortable. You may notice bright lights, colours or movement during the operation, but you will not be able to see the procedure itself.
If you are particularly nervous, tell the team before surgery. Feeling anxious is common, and your surgeon can explain the planned anaesthetic and the support available to you.
On the day of surgery, drops are used to widen the pupil and prepare the eye. You will have a final opportunity to ask questions, confirm the plan and discuss anything that is worrying you.
The operation is normally a day-case procedure, which means you go home on the same day. You will need someone to take you home, and you should not drive yourself after the operation.
Your own instructions may differ depending on your health, the planned anaesthetic and whether you are having another procedure at the same time. Always follow the advice given by your surgical team.
Most patients describe the operation as strange rather than painful. You may be aware that people are working around you and you may notice lights or a sensation of gentle pressure.
It is important to say something if you are uncomfortable. The team is there to help, and your surgeon can pause or adjust the anaesthetic if needed.
Modern cataract surgery is usually performed through a very small incision. The cloudy natural lens is removed and replaced with a clear artificial lens implant. The operation itself is commonly completed within a relatively short time, although the total time at the clinic is longer because of preparation and recovery.
Yes. Mild discomfort for the first few days is common after cataract surgery. The eye may feel scratchy, gritty or watery, and it can be more sensitive to light. Some people notice a dull ache or mild redness around the eye.
These symptoms should gradually settle. Your team will give you eye drops to support healing and reduce the risk of infection and inflammation. Use them exactly as prescribed.
Simple pain relief may be appropriate for mild discomfort, but your own surgeon or pharmacist can advise what is suitable for you, especially if you take other medication.
Severe pain is not something to simply put up with. Contact your eye-care team urgently if you have increasing pain, a very red eye, worsening vision, a significant increase in discharge or swelling, or if you are concerned for any reason.
You should also seek urgent advice if you develop sudden flashes of light, a sudden shower of floaters, or a dark curtain or shadow in your vision. These symptoms can be caused by problems that need prompt assessment.
Your post-operative instructions will include the most relevant contact details for your care. Keep them somewhere easy to find.
Vision is often blurred for the first few hours after surgery, partly because of the drops used during treatment. Many people notice improvement over the following days, but recovery is individual.
Your vision can continue to settle over the next few weeks. If you need a new glasses prescription, your optician or surgeon will advise when it is sensible to arrange this.
It is also normal for lights to seem brighter or colours to look more vivid once the cataract has been removed. This can be a welcome change, but sunglasses may feel more comfortable while the eye is settling.
Your individual instructions take priority, but common advice after cataract surgery includes:
Reading, watching television and using a computer do not damage the eye, but take a break if the eye feels tired or uncomfortable.

It is understandable to feel protective of your eyes. Many people have never had eye surgery before, and the thought of being awake can sound daunting.
In practice, the team will have performed this type of procedure many times. The operation is carefully planned, the eye is numbed and you are monitored throughout. Asking questions in advance, bringing a list of concerns and arranging practical support for the journey home can all make the day feel calmer.
Cataract surgery should never feel like a decision you have to rush. A consultation is an opportunity to discuss your vision, your lifestyle, lens options, the anaesthetic plan and the recovery you can expect.
