Epithelial Ingrowth Under LASIK Flap After a Massive Shockwave From the Port of Beirut Ammonium Nitrate Explosion

Abstract

PURPOSE: To present a case of epithelial ingrowth under a laser in situ keratomileusis (LASIK) flap as a direct result of a pressure shockwave without direct blunt trauma to the eye. METHODS: Case report RESULTS: A 27-year-old woman developed epithelial in-growth under the LASIK flap interface after a massive shock-wave trauma to the eye caused by the 2020 Port of Beirut explosion. No flap dislocation, folds, or tears had been noted on examination after the trauma. Observation with close follow-up was elected. The vision and area of ingrowth remained stable over 1 year of follow-up. CONCLUSIONS: Pressure shockwave from an immense blast can mimic direct blunt trauma in eyes after LASIK and can result in epithelial ingrowth. Treatment should be tailored to vision, flap condition, and progression. [J ournal of Refractive Surgery Case Reports. 2022;2(2):e26–e28.]
