detachment during cataract surgery: etiology and management.
Pathologic autopsy showed narrow palpebral fissures, a long philtrum, cupid's bow upper lips with a thin vermilion border, and facial hirsutism and low-set ears (Figures 3 and 4), bilateral absence of corneal endothelium and Descemet membrane
, bilateral optic nerve degeneration (Figures 5 and 6), bilateral cataracts, agenesis of the corpus callosum, and hydrocephalus.
In some diseases such as Fuchs Dystrophy or following cataract surgery, the endothelial cells and Descemet membrane
are damaged, causing the cornea to become waterlogged and the vision to become clouded.

The aim of our article is to report a case of a Descemet membrane
's (DM) detachment after radial keratotomy (RK) resolved without surgical intervention.

With advances in keratoplasty there is a move towards disease-specific procedures where the endothelial layers are grafted selectively, namely Descemet stripping endothelial keratoplasty (DSEK) (see Figures 3 and 4) when created manually, or referred to as Descemet stripping automated endothelial keratoplasty (DSAEK) when the graft is created by a mechanical microkeratome, or more recently Descemet membrane
endothelial keratoplasty (DMEK) (see Figure 5 and 6).
A transparent cornea on the front surface of the eye is very essential for a clear retinal image.2 As far as the histology of cornea is concerned, it is composed of five different layers from anterior to posterior (epithelium, Bowman's layer, stroma, Descemet membrane
and endothelium).3-5 Any change in the anatomy/physiology of cornea results in loss of transparency to some extent.
The innovation - called descemet membrane
endothelial keratoplasty (DMEK) - saw him transplant a single layer of cells the width of one tenth of a human hair onto the eye of Farnley Tyas resident Joan Greenwood at Calderdale Royal Hospital.
It is important to note that the surgeon should avoid forcing viscoelastic material in Schlemm's canal when the micro-cathether encounters a stop during the cannulation; this may rupture the canal and cause descemet membrane
