Patient: 45 years of age, male, BCVA 0.6. General Medical History: empty. Ocular Medical History: in 2003 Laser-assisted in Situ Keratomileusis, in 2014 ocular blunt trauma with flap dislocation, and epithelial cell growth into the interface, in 2014 two flap-lift retreatments with surgical flap reposition, good visual recovery. Purpose: to visualize corneal structural changes and epithelial ingrowth in a young male patient after a blunt trauma with LASIK flap dislocation after LASIK 11 years ago. Methods: Colour Photography Anterior Segment, Anterior segment optical coherence tomography (SL-OCT), Topography (Tomey)) Findings: Colour Photography Anterior Segment: Focal area of epithelial ingrowth. SL-OCT: epithelial ingrowth underneath the flap, no flap stromal edema. Topography: irregular astigmatism. Discussion: Interface complications include infectious keratitis, diffuse lamellar keratitis, central toxic keratopathy, pressure-induced stromal keratopathy (PISK), and epithelial ingrowth. Güell J et al. (1) reported a low incidence of epithelial ingrowth after regular LASIK. From a total of 7520 LASIK refractive eyes, 13 eyes with epithelial ingrowth were treated. Randleman JB et al. (2) described epithelial ingrowth as a LASIK interface complication. Epithelial ingrowth is easily distinguishable from other interface complications and may be self-limited or require flap lift to treat irregular astigmatism and prevent flap melt. Literature: (1).
