Double drape tectonic patch with cyanoacrylate glue in the management of corneal perforation with iris incarceration.

magnification and using at least periodic-acid Schiff staining because this highlights DM brightly. If no residual stroma is seen on light microscopy, samples should then be sent for electron microscopy. Ideally, more than one surgeon should perform the dissection to account for any subtle differences in the technique. The question of dissection planes in EK is important. There is currently debate in the corneal community as to whether we should be pursuing Descemet membrane endothelial keratoplasty or whether ultra-thin Descemet stripping endothelial keratoplasty provides satisfactory visual results. Unless we know the dissection plane in pneumodissection EK, we cannot answer this question.
