title: Intraoperative vertical gas breakthrough during clear corneal incision creation with the femtosecond cataract laser.
abstract: We report the occurrence and management of intraoperative vertical gas breakthrough during clear corneal incision creation with the femtosecond laser (Catalys) in 2 patients. Both eyes were managed by creation of a keratome incision, and the surgery was completed uneventfully. There were no postoperative complications. We believe that wound architecture and corneal clarity in the area of wound creation predispose to the occurrence of vertical gas breakthrough. Careful inspection of wound integrity can provide clues to an incomplete wound.
