Is cataract surgery painful?
A short, honest answer from a consultant eye surgeon — plus what you'll actually feel.
No — modern cataract surgery is not painful. The eye is fully numbed with drops, the operation lasts 15–20 minutes, and most patients describe pressure or awareness rather than pain.
What you actually feel
Cataract surgery in 2026 uses topical anaesthetic drops that completely numb the surface of the eye within a minute. You feel pressure, not pain. Patients often describe watching bright soft lights move across a red or orange background — the anaesthetic and operating microscope block any view of instruments, so nothing looks frightening.
During the 15 minutes
- The eyelid is gently held open with a small clip — you don't have to try not to blink.
- You'll hear a soft humming as the phaco probe breaks up the cataract with ultrasound.
- You may feel cool fluid rinsing across the eye — that's the irrigation keeping the eye pressurised.
- The new lens implant is slid through a 2.2 mm incision that self-seals — no stitches, no bandage.
Afterwards
For 24–48 hours the eye feels gritty, watery and light-sensitive — like having an eyelash caught. This is not the same as pain and settles fully by the end of the first week. Paracetamol is enough for the handful of patients who need anything at all.
Frequently asked questions
Is cataract surgery painful?
No. Modern cataract surgery is not painful. The eye is completely numbed with anaesthetic drops (sometimes a small injection around the eye), and 97% of patients describe the operation as pressure or awareness rather than pain. You are awake but comfortable, the surgery takes 15–20 minutes and you can talk to the surgeon throughout.
What does cataract surgery feel like?
Most patients feel a mild pressure sensation on the eye, see bright lights and moving colours (which many describe as calming) and hear the gentle sound of the phacoemulsification probe. There is no sharp or stinging pain. You will not see instruments coming towards the eye — the anaesthetic and microscope light block that view.
Is the anaesthetic injection painful?
Most cataract surgery in 2026 uses topical anaesthetic drops only — no injection at all. When a sub-Tenon's or peribulbar injection is used (usually for more complex eyes), it is given after strong numbing drops have already been applied, so it feels like brief pressure rather than a sharp needle.
Does the eye hurt after cataract surgery?
Discomfort after cataract surgery is usually described as gritty, scratchy or like an eyelash in the eye for 24–48 hours. Genuine pain is uncommon and usually settles with paracetamol. A throbbing, deep ache with redness or worsening vision is not normal — call the clinic straight away if that happens.
Will I be awake during cataract surgery?
Yes, you will be awake but relaxed. A mild oral sedative can be given if you feel anxious. General anaesthetic is available for patients who cannot lie still or have severe anxiety, but is rarely needed — over 95% of our patients have topical anaesthetic only.
How can I stay calm during cataract surgery?
The single biggest factor is knowing what to expect. Ms Pearsall talks you through every step in real time, plays gentle music of your choice in theatre, and you can squeeze the nurse's hand throughout. Focused breathing and knowing the operation is only 15 minutes helps most patients relax quickly.
