Sharma N, et al. - In this prospective interventional case series, researchers evaluated the usefulness of microscope-integrated intraoperative optical coherence tomography (Mi-OCT) for performing Descemet membrane endothelial keratoplasty (DMEK) in corneas with poor visualization. For this analysis, they involved 25 consecutive cases of corneal decompensation with poor visualization that underwent Mi-OCT-guided DMEK at a tertiary eye care centre. In 72% of cases, complete graft attachment was noted. In cases with poor visualization, Mi-OCT helps to identify the anatomy and dynamics of the host descemet membrane (DM), DM roll and anterior chamber, and is a useful tool when conducting DMEK in such cases.
