Incomplete FlapsFemtosecond LASIKAn incomplete flap may happen with femtosecond LASIK if suction proves to be unsuccessful, despite repeated attempts Ebook LASIK emergencies – A video primer: Part 2 after an initial aborted pass. It may also occur if the tear meniscus, debris, ink marks, or epithelial defect shields an area of the flap from the laser ablation. The incidence of incomplete flaps with femtosecond LASIK is approximately 0.03%.112Microkeratome LASIKIncomplete flaps may occur with m Ebook LASIK emergencies – A video primer: Part 2icrokeratome LASIK after loss of suction.
