- LASIK is not painful. Anesthetic eye drops numb the eye completely before the procedure begins.
- You may feel mild pressure during the procedure, but not pain.
- Mild post-operative discomfort such as grittiness, light sensitivity, or dryness is normal and typically resolves within a few hours.
- Serious complications are very rare.
- Most patients report that the experience was easier and quicker than they expected.
Feeling anxious before any surgery is completely natural. And when that surgery involves using a laser on your eyes, it is understandable to wonder whether the procedure might be painful.
The good news is that LASIK eye surgery is not painful. There may be some mild discomfort both during and after the procedure, but that is about it. You can put your worries aside and approach your surgery with confidence.
Is LASIK Painful? What to Expect During the Procedure
LASIK (Laser Assisted In Situ Keratomileusis) is a long-established procedure that has been proven to be extremely safe and free from pain. It uses a laser to reshape the cornea, the front part of the eye, so that light is directed more accurately onto the retina, producing clearer vision.
When you arrive at the clinic, your eyes will be checked and you will be prepared for surgery. Anesthetic eye drops are applied to numb your eyes, and your eyelids are held open by a small device. If you are feeling particularly anxious, a mild sedative may be given to help you relax.
A femtosecond laser or a surgical instrument known as a microkeratome is used to create a thin flap in the cornea. This flap is folded back and an excimer laser reshapes the underlying tissue in line with your current prescription. Once complete, the flap is repositioned and adheres naturally without the need for stitches. Both eyes can typically be treated within 15 minutes.
How Numbing Eye Drops Keep You Comfortable During LASIK
The primary reason patients experience no pain is that the anesthetic eye drops numb the eye quickly and effectively before the procedure begins. A mild sedative, if required, helps with relaxation.
While there is no pain, you may notice a coolness from the numbing drops and a slight pressure on the eye from the laser. The lasers used are precise instruments that reshape the cornea without disturbing surrounding tissue, keeping any sensation to a minimum. You may be aware of a faint smell during the laser portion of the procedure.
You will remain conscious throughout and can even speak with your surgeon. Most patients find the procedure is over before they have had time to feel anxious about it.
Managing Normal Post-LASIK Eye Discomfort and Soreness
Recovery after LASIK is generally brief. Once the anesthetic wears off, you may experience some or all of the following for a short period:
- Mild stinging, grittiness, or dryness in the eye, sometimes similar to the sensation of an eyelash being present.
- Light sensitivity or mild watering of the eye.
- Blurred or foggy vision.
These symptoms typically resolve within a few hours, although some dryness or redness may persist for a few weeks while corneal nerves continue to heal.
You can manage these effects by:
- Applying prescribed lubricating eye drops at regular intervals.
- Resting or napping when you arrive home to sleep through the initial effects.
- Wearing the protective eye shield provided for the first two to three nights.
- Taking any prescribed pain relief or anti-inflammatory medication as directed.
- Wearing sunglasses outdoors to reduce light sensitivity.
- Staying well hydrated and maintaining a comfortable environment.
- Avoiding screens for the first 24 to 48 hours.
- Refraining from rubbing your eyes and protecting them from dust and grit.
It is important to follow the aftercare plan provided by your clinic. Doing so will help symptoms resolve quickly and support optimal healing.
Problems are very rare but can include a sudden deterioration in vision, excessive discharge, increased redness, or discomfort that worsens or persists beyond one day after the procedure. If you experience any of these, contact your clinic promptly. You can learn more about what to expect at our safety information page.
Real Patient Experience: What LASIK Actually Feels Like
Most people who have undergone LASIK surgery express surprise at how comfortable the experience was. Many admit to feeling nervous beforehand, but find their concerns were unfounded; the most they felt was a brief, mild pressure lasting just a few seconds.
The general consensus among LASIK patients is that the procedure was quicker and easier than expected. Vision improvement is often noticed almost immediately after surgery, and recovery times are typically faster than anticipated, with most patients able to drive and resume normal activities from the following day.
Patients consistently report a positive experience, frequently attributing this to the skill of their surgeons and the reassuring, attentive approach of the clinical team, who talk patients through every step of the procedure in real time.

Frequently Asked Questions
Is LASIK eye surgery painful?
No. LASIK is not painful. Anesthetic eye drops are applied before the procedure to numb the eye completely. Patients may feel a mild pressure sensation during the procedure, but not pain. Any mild discomfort following surgery, such as grittiness or light sensitivity, typically resolves within a few hours.
How long does discomfort last after LASIK?
Most patients experience only mild discomfort for a few hours following LASIK. Some dryness or redness may persist for a few weeks as the corneal nerves heal, but this is manageable with prescribed lubricating drops and standard aftercare guidance.
What should I do if I feel pain after LASIK?
Mild grittiness or sensitivity in the hours following surgery is normal. However, if you experience significant pain, a sudden worsening of vision, heavy discharge, or discomfort that increases rather than improves, contact your clinic promptly. Serious complications after LASIK are very rare, but any unusual symptoms should always be assessed quickly.
Will I be awake during LASIK?
Yes. LASIK is performed under local anesthetic using eye drops, not general anesthetic. You will be fully conscious throughout but will feel no pain. If you are particularly anxious, a mild oral sedative may be offered to help you relax. The procedure itself typically takes around 15 minutes for both eyes.
