This video describes a variety of difficult situations arising due to suction loss during femtosecond and microkeratome LASIK and small-incision lenticule extraction, intraoperative modifications, and postoperative outcomes. Creation of the flap is perhaps the most critical step in LASIK. Although the femtosecond laser has improved precision and predictability of the flap, the soft docking techniques used in the newer machines increase the chance of suction loss, which can lead to incomplete flaps.
