One of the most critical post-LASIK instructions is: do not rub your eyes. This rule is particularly important in the first 3–6 months after surgery. Here is why — and what to do instead.
Why Rubbing Is Dangerous After LASIK
After LASIK, the corneal flap adheres firmly within hours through natural healing, but the edges are not fully bonded for the first 3–6 months. Vigorous rubbing can:
- Displace the corneal flap — a medical emergency requiring immediate repositioning
- Introduce infection — hands harbour bacteria that contaminate the healing surface
- Cause corneal ectasia — repeated pressure on the cornea can cause progressive corneal bulging in susceptible individuals
What to Do When Eyes Feel Itchy or Irritated
- Instil preservative-free artificial tear drops immediately — most itching is dry-eye related
- Gently dab (never rub) the closed eyelid with a clean, soft tissue
- Apply a cold compress over closed eyes for soothing relief
- Contact your surgeon if irritation persists or is accompanied by pain or sudden vision change
How Long Must You Avoid Rubbing?
Our surgeons advise avoiding eye rubbing for at least 6 months after LASIK. Even after full healing, avoiding habitual eye rubbing is good practice, as chronic rubbing can cause corneal thinning over years even in non-LASIK patients.
