PDEK can be combined with glued IOL technique

Globally, bilateral corneal blindness is estimated to affect 4.9 million individuals and unilateral corneal blindness affects 23 million individuals. A subset of corneal blindness is secondary to endothelial decompensation.A combination of a corneal transplantation procedure with a glued posterior chamber IOL with an intrascleral pocket haptic fixation attempts to correct a cloudy cornea and pseudophakic requirements for optimal visual rehabilitation of the patient. Corneal clarity in cases of endothelial decompensation is usually achieved by endothelial keratoplasty, which includes Descemet’s stripping endothelial keratoplasty with donor corneal stroma and Descemet’s membrane endothelial keratoplasty without corneal stroma. In between these two is a newer procedure, pre-Descemet’s endothelial keratoplasty, which includes less stroma than with DSEK. The PDEK donor corneal disc is sturdier than the DMEK donor disc, and tissue handling may be relatively easier with PDEK. However, the donor disc preparation is different in PDEK compared with DMEK.
