To review the outcome of 3 techniques for managing type 2 bubbles (between Descemet's membrane [DM] and stroma) formed during big bubble (BB) deep anterior lamellar keratoplasty (DALK) in different corneal pathologies. ⋯ DM baring techniques should be avoided in eyes with type 2 BB. Instead, deep stromal dissection searching for an incomplete type 1 bubble or using one of the manual dissection techniques as a guide to the clear pre-Descemetic stroma is safer and more reliable.
