Diffuse lamellar keratitis after laser in situ keratomileusis associated with surgical marker pens.

Purpose: To describe a series of cases of diffuse lamellar keratitis (DLK) after laser in situ keratomileusis (LASIK) associated with intraoperative use of a surgical marker pen.

Setting: Singapore National Eye Centre, Singapore, Singapore.

Methods: A review of all 115 patients (125 eyes) who had myopic LASIK from July 23 to July 26, 2007, was performed to determine whether eyes in which the Codman surgical marker pen (Johnson & Johnson Medical) was used intraoperatively developed postoperative DLK.
