Post-LASIK dry eye is a well-known, highly prevalent side effect of the surgery. Studies indicate that between 20 percent and 50 percent of patients experience some degree of dry eye symptoms in the first few months following LASIK. This condition is typically temporary, but it is the most common complaint after the procedure, requiring proactive management to ensure comfortable healing.

The creation of the corneal flap during the LASIK procedure temporarily severs some of the sensory nerves on the cornea. This nerve damage reduces the feeling on the ocular surface, interrupting the feedback loop that signals the brain to produce tears. The reduced tear production leads to temporary or acute dry eye symptoms.
Post-surgical symptoms are typically temporary, lasting from three to six months. As the corneal nerves regenerate, the tearing reflex is slowly restored, and the symptoms gradually diminish. In a small percentage of patients (less than 5 percent), symptoms can persist for over a year or become chronic, requiring long-term treatment.
Patient risk factors for chronic dryness are clear. Individuals with pre-existing dry eye disease are at significantly higher risk for severe or prolonged post-LASIK symptoms. Other risks include older age, female gender, and high-power corrections. Patients must be screened rigorously for dry eye before surgery is approved.
Necessary post-operative management strategies are crucial for comfortable healing. Patients are typically prescribed a strict regimen of preservative-free artificial tears, often required every hour in the initial weeks. Punctal plugs may also be inserted to retain natural tears, maximizing surface lubrication.
Dryness severely affects visual acuity during recovery. An unstable tear film causes the vision to fluctuate and appear blurry. Consistent use of lubricating drops is necessary to maintain a smooth corneal surface and optimize the sharpness of the newly corrected vision.
No, wearing contacts is advised against during the recovery period, as it would worsen the dryness and interfere with healing.
Yes, fluctuating vision is common in the first few months, often caused by the unstable tear film.
Yes, steroid drops are typically used in the first few weeks to manage inflammation and aid healing, alongside lubricating drops.
If your dry eye symptoms are severe, persistent beyond six months, or not adequately relieved by prescribed drops, schedule a follow-up with your surgeon. Further treatment, such as punctal plugs or prescription anti-inflammatory therapy, may be necessary.
