Laser eye surgery has revolutionised vision correction, offering freedom from glasses and contact lenses for millions worldwide. Yet, one of the most common temporary side effects experienced after procedures such as LASIK, PRK, LASEK, and SMILE is dry eyes. At Blue Fin Vision® Eye Clinic, our top-rated team of leading surgeons and specialists in London provide the best outcomes, using advanced technology and a personalised approach to care. Understanding why dry eyes occur after laser eye surgery – and how they are managed – can help you make an informed, confident decision about your vision.
What Are Dry Eyes?
Dry eyes occur when the eyes do not produce enough tears or when the tears evaporate too quickly, leading to discomfort, grittiness, blurred vision, or a sensation of burning. This condition can affect anyone, but it is particularly relevant after laser eye surgery, where temporary changes to the eye’s surface and nerve supply can disrupt normal tear production.
Why Does Laser Eye Surgery Cause Dry Eyes?
- Disruption of Corneal Nerves
All forms of laser eye surgery – including LASIK, PRK, LASEK, and SMILE – involve reshaping the cornea to correct refractive errors. During this process, some of the tiny nerves within the cornea are inevitably disrupted. These nerves play a crucial role in signalling the brain to produce tears. When they are temporarily impaired, the feedback loop that controls tear production is reduced, leading to dry eyes.
- LASIK: Involves creating a thin flap in the cornea, which can affect more corneal nerves and may result in a higher risk of temporary dryness.
- PRK and LASEK: Surface procedures that also disrupt corneal nerves, but in a different pattern compared to LASIK.
- SMILE: Utilises a much smaller incision, preserving more of the corneal nerves and typically resulting in a lower risk of dry eye symptoms.
- Inflammatory Response
The healing process after laser eye surgery triggers a mild inflammatory response on the ocular surface. This inflammation can temporarily reduce the quality and quantity of tears, contributing further to dry eye symptoms in the weeks following the procedure.
- Pre-existing Dry Eye Disease
Many patients already have mild or moderate dry eye before surgery, often without noticeable symptoms. Laser eye surgery can temporarily exacerbate this underlying condition. This is why a thorough pre-operative assessment at a top-rated eye clinic, such as Blue Fin Vision®, is essential to identify and manage any risk factors.
- Changes to Tear Film Stability
Laser eye surgery can alter the shape and contour of the cornea, which may affect how tears spread across the eye’s surface. This can lead to increased evaporation or instability of the tear film, causing transient dryness.
How Common Are Dry Eyes After Laser Eye Surgery?
Dry eyes are the most frequently reported side effect after laser vision correction. Most patients experience some degree of dryness in the first few week’s post-surgery. For the majority, symptoms are mild and resolve as the corneal nerves regenerate – usually within three to six months. Only a small minority experience persistent symptoms beyond this period, especially when treated at a leading clinic with top specialists and advanced technology.
Symptoms of Dry Eyes After Laser Eye Surgery
Patients may notice:
- Gritty, sandy, or burning sensations
- Fluctuating or blurred vision
- Sensitivity to light
- Redness or irritation
- Excessive tearing (a reflex response to dryness)
These symptoms are typically temporary and improve as the eye heals.

At Blue Fin Vision®, our Harley Street team of top doctors and leading surgeons are committed to minimising your risk of dry eyes and providing tailored aftercare. Our approach includes:

- Targeted Aftercare: Post-operative care includes lubricating eye drops, anti-inflammatory medication if needed, and regular follow-up appointments to monitor healing and address any symptoms promptly.
