%X Purpose: The aim of this study was to describe a case of spontaneous Descemet layer dissection without pneumodissection in femtosecond laser-assisted mushroom-type deep anterior lamellar keratoplasty.Methods: This study is a case report.Results:  A 46-year-old woman diagnosed with reticular dystrophy underwent, in her left eye, mushroom configuration femtosecond laser-assisted DALK (F-DALK). After laser trephination and removal of the superficial stroma using manual dissection, a type 2 BB formation was observed intraoperatively in the AS-OCT without signs of an associated microperforation. A deeper stromal removal was accomplished by layer-by-layer manual dissection, while the BB persisted. After stromal dissection, the donor cornea was secured with 8 interrupted 10-0 nylon sutures. The next day AS-OCT showed a detachment of DM. After 1 week, a spontaneous resolution of the DM detachment was observed.Conclusions:  This unknown F-DALK intraoperative complication has been detected through intraoperative AS-OCT images which may improve our understanding of F-DALK surgery and possible complications associated with femtolaser-assisted procedures.
