No, cataract surgery is not painful. Your eye is numbed with anaesthetic drops — and sometimes a local injection — before the procedure begins, so you should not feel pain during surgery, only gentle pressure and awareness of light and movement. Afterward, most patients have only mild, short-lived discomfort that settles well with the drops and tablets your surgeon prescribes.
Is Cataract Surgery Painful? What to Expect Before, During and After
Almost every patient asks me some version of the same question before cataract surgery: “Doctor, will this hurt?” It’s a fair worry — you’re being told your eye will be open and worked on while you’re awake. But the honest, one-word answer is no. Cataract surgery is not a painful procedure.
I’ve walked thousands of patients through this exact conversation, and the fear is almost always bigger than the reality. Modern cataract surgery is done under local anaesthesia, takes about 10–15 minutes per eye, and most people describe it as “strange” or “pressured” rather than painful.
In this article, I’ll explain exactly what anaesthesia is used, what sensations are normal during surgery, what discomfort to expect afterward, and — most importantly — which symptoms are not normal and need you to call your surgeon.
NOTE: Cataract surgery is usually not painful because it is performed under local anaesthesia, with most patients experiencing little or no pain during the procedure. Some mild discomfort, watering, or irritation can occur afterwards, but significant pain is not expected and should be reported to your eye surgeon.
What You May Feel — Before, During and After Surgery
Every stage of cataract surgery comes with its own, entirely normal sensations. Knowing what to expect at each point takes away most of the anxiety.
| Symptom | What It Means | What To Do About It |
| Mild anxiety before surgery | Normal, even though the procedure itself isn’t painful | Ask about a mild sedative for the night before if you’re not sleeping well |
| Brief stinging when numbing drops go in | The anaesthetic drops sting for a few seconds as they take effect | This settles quickly on its own; mention it if it doesn’t ease within a minute |
| Sensation of pressure during surgery | You may feel gentle pressure as instruments touch the eye — not pain | Stay still, breathe normally, and let your surgeon talk you through each step |
| Bright lights, shadows or movement | Your eye is open and awake, so light and motion register even though you can’t see the instruments in focus | Keep your gaze fixed where instructed by your surgeon |
| Watering or grittiness a few hours later | The anaesthetic is wearing off and the surface of the eye is healing | Use the lubricant drops prescribed, exactly as directed |
| Mild ache or brow-line heaviness that evening | Common, low-grade post-operative discomfort | A surgeon-approved over-the-counter analgesic usually settles this within a day |
| Light sensitivity for 24–48 hours | The eye is more sensitive to light while it heals | Wear the protective shield or sunglasses provided, especially outdoors |
| Occasional itching in the first week | Normal part of surface healing | Do not rub the eye; use a cold compress over closed lids if your surgeon advises it |
Types of Anaesthesia Used in Cataract Surgery
Not every patient receives the same anaesthesia. Your surgeon chooses based on your eye, your general health, and how comfortable you are lying still.
| Anaesthesia Type | What It Means For You | What To Ask Your Surgeon |
| Topical anaesthetic drops | Numbing drops instilled just before surgery — the standard approach for most routine cataract surgeries | Whether this alone is planned for your case |
| Intracameral anaesthetic | An additional numbing agent placed inside the eye during the procedure for extra comfort | Ask if this will be used alongside the drops |
| Peribulbar block (local injection) | An injection around, not into, the eye that numbs it more completely; used when more anaesthesia is needed | Why it’s recommended for you, and what the injection itself will feel like |
| Intravenous sedation | Medication through a vein to help you relax, without putting you fully to sleep | Discuss this if you have significant anxiety or find it hard to lie still |
| General anaesthesia | Rare; reserved for patients who cannot follow instructions, lie flat, or stay still — such as advanced dementia, severe tremor, or young children | Whether your medical history makes this necessary, and what pre-anaesthesia checks are needed |
When To See a Doctor
Mild discomfort in the first day or two is expected. The following are not, and need prompt attention:
- Sudden or severe pain that isn’t settling with the medication prescribed
- Redness that is worsening rather than improving day by day
- Discharge from the eye, especially if it’s thick, yellow or green
- A sudden drop in vision, or new flashes of light and floaters
- Halos around lights that are getting worse, not better
- Nausea or vomiting together with eye pain
- Fever alongside eye symptoms
If you notice any of these, call your eye surgeon the same day — do not wait for your next scheduled follow-up.

Home Measures That Help
- Follow your drop schedule exactly — timing and sequence matter as much as the drops themselves
- Wear the protective shield at night for the first week to avoid accidental rubbing while asleep
- Keep your hands away from the eye; never rub or press on it
- Avoid swimming pools, dusty environments and eye make-up for as long as your surgeon advises
- Wear sunglasses outdoors, even on cloudy days, for the first week
- Avoid heavy lifting, bending forward sharply, or straining for a few days
Medical & Treatment Options
Before Surgery
A pre-operative regimen of antibiotic drops is usually started a day or two before surgery to reduce infection risk. If you’re especially anxious, your surgeon may prescribe a mild sedative for the night before, so you’re well rested.
During Surgery
Anaesthesia — drops, an intracameral agent, or occasionally a peribulbar block — is chosen to keep you comfortable throughout. Your surgeon will keep talking to you during the procedure, which itself helps most patients relax.
After Surgery
You’ll typically be given a combination antibiotic-steroid eye drop to control inflammation and prevent infection, along with lubricant drops for grittiness. For discomfort, an over-the-counter analgesic your surgeon has approved is usually enough. Oral anti-inflammatory tablets are occasionally added for a day or two if needed. True pain — as opposed to mild ache or grittiness — is uncommon, and should always be reported rather than simply managed at home.
Frequently Asked Questions
Does cataract surgery hurt during the procedure?
No. Your eye is numbed with anaesthetic drops, and sometimes an additional injection, before the surgery starts. Most patients feel pressure or awareness of light and movement, but not pain. You remain awake, and your surgeon talks you through each step.
How much pain is normal after cataract surgery?
Most patients have only mild discomfort — grittiness, watering, or a dull ache — for the first day or two as the anaesthetic wears off. This usually responds well to the drops and any approved analgesic your surgeon prescribes.
Why does my eye feel gritty after cataract surgery?
Grittiness is a normal part of the surface healing as the tiny incision seals and the eye’s surface recovers. Using your lubricant drops as prescribed usually settles this within a few days.
Is a peribulbar block injection painful?
The injection itself is brief and typically produces a moment of pressure rather than sharp pain, since the surface is numbed first. It’s used only when your surgeon feels additional anaesthesia will make your surgery more comfortable.
How long does discomfort after cataract surgery last?
For most patients, noticeable discomfort settles within 24 to 48 hours. Mild grittiness or light sensitivity can continue for a week as healing completes, but should steadily improve, not worsen, each day.
When should I worry about pain after cataract surgery?
Worsening pain, increasing redness, discharge, sudden vision changes, or pain with nausea or fever are not normal and need same-day attention from your eye surgeon — they can signal infection or inflammation that needs prompt treatment.
Key Takeaways
- Cataract surgery itself is not painful — your eye is numbed before the procedure begins
- You’ll likely feel pressure, light and movement, but not sharp pain, while awake during surgery
- Mild grittiness, watering or ache in the first day or two is normal and expected
- Prescribed drops and an approved analgesic are usually all that’s needed for comfort
- Worsening pain, redness, discharge, or vision changes are red flags — call your surgeon the same day
- General anaesthesia is rarely needed and reserved for specific situations
