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

Descemet’s Stripping Automated Endothelial Keratoplasty – A Review
Descemet’s stripping automated endothelial keratoplasty (DSAEK) has become the procedure of choice to treat corneal endothelial dysfunction. The technique involves replacing the diseased host endothelium with a graft consisting of a thin layer of posterior stroma, Descemet’s membrane and endothelium. In comparison with penetrating keratoplasty (PK), DSAEK confers quicker visual and structural r...

PURPOSE To evaluate the use of a femtosecond laser combined with a microkeratome in the preparation of posterior corneal disks for Descemet stripping automated endothelial keratoplasty (DSAEK). METHODS This experimental study involved ultrathin DSAEK tissue preparation of 22 donor corneas unsuitable for transplantation. The first cut was performed with an Intralase® FS60 laser and the second ...

AIM To perform Descemet stripping automated endothelial keratoplasty (DSAEK) using a novel technique to obtain very thin (<100 µm) posterior corneal disks. METHODS Twenty five DSAEK grafts were prepared with two sequential cuts: the first cut, of variable thickness, was made with a femtosecond laser and the second with a 300 µm microkeratome head. Spectacle corrected visual acuity, endothelia...

PURPOSE To report the technique of combining the two different polarization filters to detect the flap edge of the corneoscleral tissue before trephining the Descemet's stripping automated endothelial keratoplasty (DSAEK) tissue. METHODS A human DSAEK donor tissue was prepared with mechanical microkeratome and the tissue on the cutting block was brought under the microscope. The liner, circul...

343 The emergence of endothelial keratoplasty (EK) represents the beginning of a new era in the treatment of corneal endothelial disorders which continues to evolve. Fifteen years ago we were performing penetrating keratoplasty for Fuchs’ dystrophy and bullous keratopathy but nowadays we are performing selective replacement of the diseased endothelial layer. In recent years two techniques of EK...
