Does LASIK or LASEK Cause Dry Eyes?

Does LASIK or LASEK Cause Dry Eyes?

Some people believe that undergoing LASIK or LASEK leads to dry eyes. However, wearing contact lenses is actually more likely to cause dry eyes than having LASIK or LASEK surgery. However, due to the reduction of tear production after LASIK and LASEK, some degree of dryness can still occur.

What’s The Difference Between LASIK and LASEK?



LASIK surgery involves creating a corneal flap, while LASEK removes the corneal epithelial layer to reshape the cornea with laser. Both procedures can result in some damage to the corneal nerves.



When your eyes become dry, they trigger a reflex that stimulates tear production. For this mechanism to function properly, the corneal nerves must be intact. However, if these nerves are damaged during LASIK or LASEK, the eye’s ability to respond to dryness can be impaired. This is considered a complication related to tear function after the surgery.



The dry eye symptoms can differ between LASIK and LASEK. After LASIK, dry eye symptoms often appear in the afternoon due to eye fatigue. In contrast, after LASEK, people may feel pain or discomfort in the morning upon waking.

For patients particularly concerned about dry eyes, SMILE LASIK can be a better option. SMILE uses a laser to create a small incision and remove corneal tissue without damaging the surface nerves as much, resulting in significantly less risk of dry eyes.
