In the very unlikely event that your LASIK flap has moved, you will definitely know it. A flap dislocation would cause notable pain, discomfort, excessive watering in the eye, and/or blurred vision.
How common is flap dislocation after LASIK?
Postoperative laser-assisted laser in situ keratomileusis (LASIK) flap dislocation occurs in approximately 1%-2% of patients, and the greatest risk of non-traumatic flap shift occurs within the first post-operative day after the surgery, presumably as a result of a mechanical trauma[1]–[3].Can the flap Move years after LASIK?
Most dislocations occur in the early postoperative period as a result of mechanical disruption such as forceful blinking or eye rubbing. However, Schmack et al. showed that LASIK flaps may be lifted without complications up to 8 years, 5 months after initial surgery.Does the LASIK flap never fully heal?
MYTH: The corneal flap never heals.Once the surgery is over, the flap is laid back into place to heal on its own. Some people believe that the flap never actually heals. However, this is not true. The flap starts to heal within one day of having the surgery.
