A patient presents 2 weeks after LASIK with a 2 mm area of loose, curled LASIK flap epithelium at the flap margin with sheets of epithelium growing underneath the flap. This complication is best described as:
- A Diffuse lamellar keratitis (DLK)
- B Epithelial ingrowth ✓
- C Flap striae
- D Interface fluid syndrome
Correct answer: B. Epithelial ingrowth
Explanation
Epithelial ingrowth is characterized by nests or sheets of epithelium growing under the LASIK flap, typically appearing as a whitish, geographic opacity at the flap interface. It occurs in 1-2% of primary cases and is more common after enhancements or trauma. DLK presents as a granular interface infiltrate without epithelial sheets. Flap striae are folds in the flap itself.
