In recent years, endothelial keratoplasty has been commonly used as an alternative to penetrating keratoplasty as a surgical treatment for corneal endothelial pathologies. The most common form of endothelial keratoplasty is Descemet membrane stripping automated endothelial keratoplasty (DSAEK), which involves stripping the host’s Descemet membrane and endothelium and replacing them with donor p...

Descemet membrane detachment (DMD) is a sight-threatening complication that has been reported after diverse surgical procedures. Unilateral DMD typically arises as the result of engagement of the Descemet membrane during intraocular surgery. We report an unusual case of bi latera l DMD occurring spontaneously several weeks after sequential uncomplicated phacoemulsification cataract extraction. ...

PURPOSE To compare three microkeratome-assisted techniques for the preparation of ultrathin (UT) grafts for Descemet stripping automated endothelial keratoplasty. METHODS After dissection with a 300-μm microkeratome head in 40 donor tissues, a second cut was performed with a 130-μm head either after manual stromal hydration (group A, n = 10) or osmotic hydration at the eye bank (group B, n = ...

Descemet-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 membrane, and endothelium. In comparison to penetrating keratoplasty (PK), DSAEK confers quicker visual and structural recove...

BACKGROUND To report a surgical method for treating corneal oedema in a case of late-onset Descemet membrane detachment after penetrating keratoplasty. CASE PRESENTATION A 55-year old patient presented with sudden visual loss in his left eye 28 years after penetrating keratoplasty for keratoconus. Slit-lamp biomicroscopy revealed a distortion of the corneal graft anatomy with protrusion of th...

D escemet membrane endothelial keratoplasty (DMEK), the newest and most advanced form of endothelial transplantation, represents the culmination of the evolution of keratoplasty techniques. It has nudged aside its predecessor, Descemet stripping automated endothelial keratoplasty (DSAEK), just as DSAEK displaced its own forerunner, deep lamellar endothelial keratoplasty (DLEK). What differentia...

AIM To describe a novel technique for the preparation and transplantation of posterior corneal lamellae consisting of endothelium and bare Descemet membrane with a stromal supporting rim. METHODS Posterior lamellar discs for Descemet membrane endothelial keratoplasty with a stromal rim (DMEK-S) were prepared manually immediately before surgery using the big bubble technique. The retrospective...

Purpose: To report a case of double descemet membrane forming a double anterior chamber following ‘Big bubble’ DALK converted to PKP. Results: A 52-year-old man with keratoconus underwent DALK operation converted to PKP due to macro perforation of the descemet membrane. On the postoperative evaluation a remnant of the host’s descemet membrane formed a double anterior chamber. After a few months...
