Abstract
Among intraoperative LASIK complications, the buttonhole flap is perhaps the most challenging. The buttonhole flap affects the visual axis and compromises visual, anatomical, and functional recovery, as well as has significant psychological and medicolegal repercussions. While free caps and incomplete flaps do not usually cause long-term loss of vision, the buttonhole formation is the most likely complication to result in glare and substantial loss of best corrected visual acuity (BSCVA). Management also poses therapeutic risks, including the formation of subepithelial stromal scars in the visual axis and the induction of irregular astigmatism.
