Central and bullous Descemet membrane detachment during cataract wound hydration: an insightful complication in a post-DALK eye.

A 54-year-old man, with history of undergoing deep anterior lamellar keratoplasty (DALK) 20 months ago, presented with mature senile cataract in the same eye. While undergoing phacoemulsification, a large, central Descemet membrane detachment (DMD) was noted, separating the donor cornea from the host predescemetic layer. No DM tears were noted. Stromal puncture was done at the graft host junction to reduce the extent of DMD. This was followed by a large intracameral air bubble insertion, which resulted in complete resolution of DMD on the first postoperative day. DMD during hydration of wound is a unique complication to be anticipated while doing cataract surgery in an operated DALK eye.
