Summary
Late flap dislocations after laser in situ keratomileusis (LASIK) can occur up to 10 years post-surgery, even after mild trauma. Prompt management ensures full visual recovery, and inferior hinges may offer protection.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Refractive Surgery
Background:
- Laser in situ keratomileusis (LASIK) is a common refractive surgery.
- Corneal flap creation is a key step in LASIK.
- Complications, though rare, can occur years after the procedure.
Observation:
- A patient developed partial flap dislocation 10 years after uneventful bilateral LASIK for hyperopia and astigmatism.
- The dislocation occurred following mild trauma during recreational activities.
- A superior-hinged corneal flap was created using the Moria M2 microkeratome.
Findings:
- Corneal flap dislocations are possible up to a decade after LASIK.
- Mild trauma can precipitate flap dislocation years post-surgery.
- Prompt diagnosis and management are crucial for visual recovery.
Implications:
- This case highlights the long-term risk of LASIK flap dislocation.
- Recreational activities may pose a risk for flap displacement.
- Further research into the biomechanical advantages of inferior hinges is warranted.
