Donor tissue preparation for Descemet membrane endothelial keratoplasty

We are pleased to note that Dr Zarei-Ghanavati and his team have replicated our technique (originally presented at the American Academy of Ophthalmology meeting in Atlanta 2008 and subsequently published)1 and agree that it is a viable, quicker and easier alternative to conventional donor preparation for Descemet membrane endothelial keratoplasty (DMEK) surgery.2 The process of pneumatic dissection described is essentially similar to ours; however, they have overlooked some key adaptations which further maximise the potential of this novel technique. We performed a superficial keratectomy using a 300 μm microkeratome head prior to performing the pneumatic dissection. In the …
