Tourtas et al  reported re-bubbling in 82% of patients after DMEK and 20% after DSAEK. Guerra et al  reported that 33% of the DMEK eyes required a re-bubbling procedure compared with 7% of the DSAEK eyes.
Futher development in DSAEK graft preparation is pushing towards more delicate and thinner lamellae, so we can describe nanothin (NT, [less than or equal to]50 [micro]m), ultrathin (UT, [less than or equal to]100 [micro]m) and conventional ([greater than or equal to]100 [micro]m) grafts (14).
In May 2014, he underwent the first DSAEK surgery, using the standard procedure .
In the last few years, novel treatments are being utilized for failed PKP, including DSAEK and DMEK.
Background: Descemet's stripping automated endothelial keratoplasty (DSAEK) surgery offers a more standardized approach and reliable method to create corneal grafts with an instrument such as a microkeratome.
The possible therapeutic solutions we hypothesized were rebubbling (introduction of an air bubble in the anterior chamber), a DSAEK, or PK (Penetrating Keratoplasty).
Most of the available tissue following surgery contains stroma from the periphery, such as that remaining after penetrating keratoplasty, DMEK, or DSAEK procedures.
ISR, the first and only certified ISO Clean Eye Bank, plans to bring their innovative techniques, such as Nano-Cut Precise[TM] and Punch-Ready DMEK[TM], to the Louisiana location, which will provide local surgeons the ability to obtain ocular grafts for DSAEK and DMEK.
Comparison of corneal thickness and haze in DSAEK and penetrating keratoplasty.
Corneal endothelial transplant (DSAEK, DMEK & DLEK).
In fact, the BSCVA in one case improved from 20/200 to 20/50, despite the fact that the patient had been limited to 20/100 after previous DSAEK. Caution should be exercised in the selection of the candidates, including presurgical preparation such as creating an intact iris-IOL diaphragm.
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).
