A 38-year-old male post femto-Laser-Assisted In Situ Keratomileusis (LASIK) in both eyes 4 years back came with history of accidental trauma to the right eye by cardboard paper edge with complaints of pain and redness. His visual acuity was 6/6 in both eyes. Slit-lamp examination in the right eye revealed inferior flap dehiscence and was inverted from the 4 o' clock to the 7 o' clock position [Figure 1]a. The patient was managed with careful repositioning of the flap and placement of bandage contact lens and was started on topical antibiotics.

Although flaps cut with the femtosecond laser are less prone to dislocate than blade-cut flap, corneal flaps remain susceptible to trauma as late as 7 years after uneventful femto-LASIK.[1] Patient did well in the postoperative period but on follow up two months later we noticed Grade 1 epithelial ingrowth [Figure 1]b. Diffuse lamellar keratitis and epithelial ingrowth are associated with flap dislodgment.[2]
