Abstract Details

Purpose:

To present a clinical case of traumatic dislocation of a laser-assisted in situ keratomileusis (LASIK) flap in the patient with operated myopia.

Setting:

Limited Liability Company Vzglyad Medical Centre, Dnipro, Ukraine

Methods:

Presented clinical case of a 23-year-old woman with myopia of both eyes after uncomplicated LASIK. Visual acuity was 20/20 after LASIK. Blunt ocular trauma occurred 6 months after LASIK on the left eye. Slit-lamp examination didn’t revealed flap dislocation. The patient was prescribed antibacterial therapy. The patient was directed to specialized medical centeronly on the 4th day after trauma. Slit-lamp microscopy and optic coherence tomography (OCT) anterior segment was performed. Examination revealed corneal flap partially dislocated with severe fixed folds in the central optical zone. It was associated with epithelial in growth. Preoperative visual acuity was 20/200.

Results:

A reposition of the flap with a preliminary removal of the epithelium between the flap and the main corneal bed was carried out. OCT was performed after the surgery to monitor the quality of the interface cleanliness from the epithelium and the accuracy of the flap reposition. OCT control was made in dynamics. The edge of the flap was tightly attached, there were no epithelial ingrowths in the flap interface. Visual acuity was 20/20 with absence of flap stria. The patient maintained the same vision at the last follow-up.

Conclusions:

Traumatic dislocations of LASIK flaps may occur many months after uncomplicated surgery. Anterior segment OCT can efficiently visualize corneal structural changes associated with LASIK flap dislocation. Early recognition, precise control by OCT and surgical flap reposition have to be the main parts of management post-LASIC cornea trauma.
