Interface fluid syndrome (IFS) is an unusual complication after laser-assisted in-situ keratomileusis (LASIK).

Corneal edema was sustained even after the IOP was lowered to 14 mmHg. Spectral-domain optical coherence tomography scanning of the cornea revealed a diffuse, thin fluid pocket in the corneal interface. After
