Descemet Membrane Endothelial Keratoplasty

S- or F-stamping donor tissue for Descemet’s membrane endothelial keratoplasty is widely practiced to guard against DMEK’s most embarrassing potential complication: accidental upside-down graft implantation.

When starting with Descemet’s membrane endothelial keratoplasty, it is common to manually mark a ring of purple dots on the corneal surface to serve as a centering guide for the graft’s final position.

Re-bubbling a Descemet’s membrane endothelial keratoplasty graft using an in-office slit lamp may be safer than using a surgical scope, according to a presentation at the virtual American Academy of Ophthalmology annual meeting.

Physicians and patients should be aware of the likelihood of Descemet’s membrane endothelial keratoplasty graft failure and the need for repeat transplantation in the presence of previous glaucoma surgery, according to a study.

Longer graft storage time in cold media significantly reduced the elasticity of a Descemet’s membrane endothelial keratoplasty graft, with potential effects on unfolding within the anterior chamber as well as postoperative detachment rate.
