endothelial keratoplasty versus Descemet stripping automated endothelial keratoplasty.
In posterior corneal dystrophies, Descemet membrane
and corneal endothelium are involved.
Spontaneous bilateral late- onset Descemet membrane
detachment after successful cataract surgery.
As surgeons have moved away from full-thickness penetrating keratoplasty (PK), EK techniques have become increasingly precise, with a move to Descemet-stripping endothelial keratoplalsty (DSEK or DSAEK) and Descemet membrane
endothelial keratoplasty (DMEK or DMAEK).
Further chapters cover the history of lamellar and penetrating keratoplasty, deep lamellar endothelial keratoplasty (DLEK), Descemet's stripping automated endothelial keratoplasty (DSAEK), comparisons of the older form of sutureless transplantation to DSAEK, and future directions, including Descemet membrane
endothelial keratoplasty (DMEK).
In the XX century, Sato in Japan, in the 1930s, observed corneal flattening in keratoconus eyes with previous steep and thin corneas, which developed hydrops (rupture of the Descemet membrane
with subsequent hydration of the stroma) and thought that breaks in Descemet's membrane might play a role in that flattening, so he attempted to treat keratoconus creating breaks in Descemet's membrane with posterior incisions.
detachment after canaloplasty: incidence and management.
Histologically, patients with ARS have been found to have a monolayer of endothelial-like cells with descemet membrane
extending from the cornea, across the anterior chamber and angle structures on to the surface of the iris.
