LASIK (Laser-Assisted In Situ Keratomileusis) is a refractive surgery that corrects vision impairments such as nearsightedness, farsightedness, and astigmatism. The procedure reshapes the cornea, the transparent front part of the eye, to improve how light focuses on the retina. A thin, hinged flap is created on the corneal surface and lifted to allow a laser to reshape the underlying tissue. After reshaping, the flap is repositioned, adhering naturally without stitches. This flap serves as a protective layer, and its integrity is important for successful healing and clear vision.
Identifying Signs of a Dislodged Flap
A dislodged LASIK flap often causes a sudden and significant blurring or distortion of vision. This visual disturbance can range from moderate haziness to a substantial loss of clarity, differing noticeably from the mild blurriness experienced immediately after surgery.
Discomfort is also common. Individuals often report a foreign body sensation, similar to an eyelash or grit, frequently accompanied by pain or pressure.
The eye may experience excessive tearing or watering. Increased sensitivity to light (photophobia) is another common symptom, where even dim light can feel bothersome. Redness of the eye may also be apparent. A visible fold or wrinkle on the cornea might be observed, or the flap itself may appear displaced. These symptoms can manifest immediately after an incident or develop several hours later.
Understanding How Flap Dislodgement Occurs
LASIK flap dislodgement typically results from external forces impacting the eye. The flap is most susceptible to movement during the initial days and weeks following surgery, as it bonds with the underlying corneal tissue. The outer layer of the cornea, the epithelium, begins to seal the edges within one to three days, but full adhesion takes longer.
Vigorous eye rubbing is a frequent cause of flap displacement, particularly in the early post-operative period. The sideways movement can lift the flap’s edge, causing it to fold or shift. Direct eye trauma, such as a poke, blow, or sports impact, can also lead to dislodgement. Activities generating significant pressure on the eye, if performed without proper protection, carry some risk. While rare, incidents can occur years after the procedure, though the risk decreases over time as the flap strengthens its bond.
Immediate Actions If You Suspect Dislodgement
If you suspect your LASIK flap has dislodged, immediate action is necessary to preserve your vision and prevent complications. Contact your eye surgeon or an ophthalmologist without delay. This situation is an emergency, and prompt medical attention can significantly improve the outcome.
Avoid touching or rubbing the affected eye. Do not attempt to reposition the flap yourself or apply any pressure. Any manipulation could worsen the dislodgement or introduce infection.
Protecting the eye is important. Wear the protective eye shield provided after surgery, especially while waiting to see the doctor. This helps prevent accidental rubbing or further trauma. Keep the eye closed as much as possible. Seeking professional help quickly allows the surgeon to assess and often reposition the flap, which typically resolves the issue without lasting vision problems.
Preventing Flap Complications
Minimizing the risk of LASIK flap complications involves diligent adherence to post-operative guidelines. Avoiding eye rubbing is a primary recommendation, particularly in the initial weeks after surgery when the flap is most vulnerable. Patients should wear protective eye shields, especially during sleep, to prevent accidental rubbing or contact with the eyes.
Wearing protective eyewear during activities that could lead to eye injury, such as sports or certain occupations, is advised. This precaution is important even after the initial healing period. Following all prescribed post-operative instructions, including eye drops, is important for proper healing and to reduce the chance of infection or inflammation. Attending scheduled follow-up appointments allows for monitoring of the healing process and early detection of any potential issues.
