Double-pass microkeratome technique for ultra-thin graft preparation in Descemet’s stripping automated endothelial keratoplasty

摘要

Endothelial keratoplasty is evolving with increased attention placed on the optical qualities of the posterior donor lenticule. In efforts to improve visual outcomes, the effects of the thickness, smoothness, and planar profile are being studied. This paper describes a double-pass microkeratome technique to create ultra-thin (less than 100 μm) Descemet’s stripping automated endothelial keratoplasty grafts.
