Does Laser Eye Surgery Hurt? What You’ll Feel During Treatment and Recovery
Pain is often one of the first things people ask about when considering laser eye surgery, and it’s a completely understandable concern. The procedure involves one of the most sensitive parts of the body, so it makes sense to want a clear idea of what it actually feels like before deciding to go ahead.

In most cases, laser eye surgery is much more comfortable than people expect. Numbing eye drops desensitise the surface of the eye throughout, so you stay fully awake but shouldn’t feel anything sharp or cutting. Pressure and a mild sense of touch during treatment are normal, followed by some irritation in the hours after as healing gets underway.
What your experience is actually like is dependent on which procedure you have. LASIK and SMILE follow a different pattern from surface treatments such as PRK or LASEK, both during the procedure and in the days that follow. It also covers when symptoms are worth keeping an eye on and when they're not. This article works through each stage in turn, so you know what's normal before you go in.
What does laser eye surgery actually feel like?
Your eye is numbed before the surgeon starts, so the procedure itself is usually painless. You stay awake throughout and will be asked to focus on a target light, which helps keep your eye correctly positioned while the laser works.
A small clip holds the eyelids open, so blinking isn't something you need to worry about. It feels unfamiliar at first, but most people stop noticing it once treatment starts. At certain points, you'll feel a firm, brief pressure on the eye. There's no sharpness to it, just a push that lasts a few seconds. The target light may also dim or fade temporarily as the laser works, which is a normal part of the process.
Most of what happens on the day will already be familiar to you. Your consultant will walk you through the procedure in detail at your consultation, covering what each step feels like and what to expect at each stage, so you arrive knowing what's coming rather than facing anything new. On the day itself, the clinical team will talk you through each step again as it happens.
Some people still feel anxious beforehand, which is understandable given that you're awake and aware throughout. A mild sedative can be offered if needed, which won't affect your ability to follow instructions but can take the edge off.
As the numbing drops wear off after the procedure, your eye can start to sting a little. A watering or gritty feeling often follows, similar to having something caught on the surface. This is the point where discomfort is more noticeable, and it's also expected. It settles as the surface of the eye begins to recover.
Surgeon Insight
"Many LASIK and SMILE patients are surprised about how painless the procedure is, and how little discomfort they experience during recovery. I find this information helpful in allaying the anxieties of new patients. While there may be some sensations of pressure during the procedure, the anaesthetic drops ensure that there is no sharp pain."
Which type of laser eye surgery hurts more?
Regardless of the type of laser eye surgery performed, the procedures are all carried out using numbing eye drops, so the procedure itself doesn’t usually feel painful. The difference between treatments is more apparent in recovery. Surface treatments such as PRK and LASEK tend to feel more uncomfortable in the first few days, while LASIK and SMILE usually involve milder irritation that settles more quickly.
LASIK and SMILE preserve more of the outer corneal surface structure than surface treatments, which is why recovery tends to be quicker and more comfortable. PRK and LASEK work differently: the surface layer is removed during treatment and takes several days to regrow. It's this difference in the early healing that accounts for most of the discomfort.

How painful is recovery after laser eye surgery, and how long does it last?
The procedure itself should be painless. During the early stages of recovery, you’re most likely to feel irritation or discomfort - but these are normal signs that your eye is starting to heal as it should.
First few hours
The eye's surface becomes sensitive again as the numbing drops wear off. Following this, your eyes are likely to start to water, and a stinging or gritty sensation can develop, as if something were caught on the surface. This happens because the surface has just been treated and your tear film hasn't fully stabilised yet.
You're also likely to find bright light uncomfortable at this stage. The eye can be more sensitive during early healing, and the unstable tear film leaves the surface more exposed. Both of which make the eye more reactive to light. Resting with your eyes closed or in a dimmer space will feel like the most comfortable option until things begin to settle. We always advise you to bring sunglasses to your surgery appointment so you can slide them on soon after the procedure is done, to ease the light sensitivity that will improve over the next few days.
Day 1
24 hours after LASIK or SMILE, your eye will already be largely stable. Any irritation you’ll feel tends to ease significantly within the first 24 hours as your tear film recovers.
After PRK or LASEK, the surface layer of your cornea is still rebuilding. Because the outer layer hasn't fully regrown yet, your eye can feel sore and sensitive to light.
Days 2–5
With LASIK and SMILE, most of the early irritation has settled. You might find some dryness continues while the tear film stabilises, but your eye should be noticeably more comfortable by this point.
With PRK and LASEK, the surface layer is still regrowing at this point. Soreness and light sensitivity can continue, and will ease gradually as the outer layer closes over. For PRK and LASEK, days two to five are often when the discomfort is most noticeable.
1st Week and beyond
The surface of your eye will continue to settle in the weeks after your treatment. During this time, mild dryness or some fluctuation in vision can be normal, but these usually improve as you continue to heal and your tear film becomes more stable. For more details on what to expect at each stage, read our guide to laser eye surgery recovery.
What helps with discomfort after surgery?
The aim of aftercare is to keep the eye's surface protected and hydrated while it recovers.
Lubricating drops are the foundation of this. You'll be given these to keep the surface moist and reduce the gritty or dry feeling that you might feel between blinks. Anti-inflammatory and antibiotic drops are also often prescribed to control irritation and protect the surface while it heals. Using them regularly matters because the tear film doesn't restabilise on its own straight away.
The environment around you during the early recovery stages is an often-overlooked factor. Because bright light tends to feel uncomfortable in the first day or two, sticking to calmer, dimmer spaces in the first 24-48 hours will be easier on your eyes. Wearing sunglasses helps outdoors, as this is where glare is often more noticeable at this stage.
Resting your eyes, particularly in the first few hours after treatment, can reduce irritation because blinking and focusing draw attention to the healing surface. Keeping them closed for short periods is usually more comfortable than carrying on as normal. Avoid rubbing your eyes even if they feel gritty, as it’s important not to disturb the eye’s surface as it settles.
Your comfort usually improves as the eye's surface heals. Using your drops as advised helps to support this early healing phase, while missed drops or unmanaged irritation can make your symptoms more noticeable.
When is pain not normal after laser eye surgery?
Whilst some discomfort is expected in the early stages of healing, there’s a clear difference between normal irritation and symptoms that need to be checked. You shouldn’t ignore any symptoms that become more intense or don’t begin to improve. These include:
1 - Increasing pain, which suggests the eye is becoming more inflamed rather than settling
2 - Discharge, which may indicate there is an infection
3 - Reduced or worsening vision, rather than steady improvement
4 - Severe redness, especially if it increases rather than fades
These changes can indicate complications that need to be assessed promptly. If you notice any of these symptoms, contact your clinic or surgeon as soon as possible. Problems are easier to identify and treat when they’re assessed early, particularly while your eye is still healing.
If you’re not sure whether your symptoms are expected, it’s always worth checking. Most concerns are part of normal recovery, but reassurance from your clinical team can help you continue your recovery with confidence.
Next steps
Laser eye surgery is, for most people, far more comfortable than they expect. The procedure itself is usually painless, and while recovery involves some irritation, it follows a pattern that eases as the surface of the eye heals. Knowing what's normal at each stage makes it easier to go into treatment with confidence.
If you’d like to discuss the possibility of laser eye surgery and cover any concerns you might have, the clinical team at OCL Vision are on hand to help. A consultation is the right place to discuss which procedure suits your eyes, what your recovery is likely to involve, and how any discomfort would be managed along the way.
