A 24-year-old female presented on the second postoperative day after laser-assisted in situ keratomileusis (LASIK) surgery. She gave a history of rubbing her right eye (RE) on the next day after surgery. The slit lamp evaluation revealed the presence of an inferior crescent in the RE ([Figure 1]a- image captured on smartphone), and on further slit lamp examination the flap displacement [Figure 1]b was noted superiorly. Anterior segment optical coherence tomography (OCT) [Figure 1]c confirmed the above findings. Flap repositioning was done after refloating the flap. Traumatic flap displacement occurs in 1%–2% of cases more often within the first 24 hr but may also occur after 7 years.[1],[2] | Figure 1: (a) Smartphone photography showing inferior crescent shaped defect.

Immediate flap repositioning is advised in all cases to prevent epithelial ingrowth and diffuse lamellar keratitis.
