Background

This case report illustrates a late onset of diffuse lamellar keratitis (DLK, “Sands of Sahara”) triggered by a foreign body removal six months after laser in situ keratomileusis (LASIK).

DLK is a known interface complication after LASIK [1]. DLK mostly occurs in the immediate postoperative period but also late onset cases have been described [2]. An incidence of less than 3 % has been reported by most series reports [3]. The etiology of DLK is not well understood [4] but seems multifactorial [5]. Contributing factors to this non-infectious, inflammatory process are ocular inflammatory disease, epithelial defects or atopic disease [1]. However, late onset cases are most often related to inciting factors (flap dislocation, epithelial defects often related to recurrent erosions) [1].
