“…Mean postoperative BCVA is 20/40 at 3-6 months postoperatively, 5,8 and rates of patients achieving 20/40 or better following EK range from 38% to 100%. 5 Guerra et al reported that only 23% of DSAEK patients achieved VA >20/25 at 12 months follow-up, despite having otherwise healthy eyes and clear corneas with no evidence of graft failure, 44 and similar results with EK have been found by several others.…”

“…6 Epithelial ingrowth of the interface has also been reported in up to 2% of DSAEK cases, often requiring a re-graft. 8,114,119 Despite these reports, it remains uncommon for interface opacity to be visible on slit-lamp examination, and light scatter only affects visual acuity in extreme cases, 111 While small interface opacities may reduce visual quality through increased light scatter (i.e. glare), they seem unlikely to play a major role in determining visual acuity.…”

“…56 Hyperopia is increased by grafts with thick peripheries and thinner central regions acting as minus meniscus lenses. 8,141 Newer techniques with thinner grafts have produced less hyperopic shift, in the order of 0.75D. 18 Additionally, thin DSAEK and DMEK result in only slight changes in astigmatism, 17,45 unlike thicker DSEK / DSAEK that may induce up to 0.6D of cylinder.…”

Endothelial keratoplasty is now favored over full-thickness penetrating keratoplasty for corneal decompensation secondary to endothelial dysfunction. Although endothelial keratoplasty has evolved as surgeons strive to improve outcomes, fewer patients than expected achieve best corrected visual acuity of 20/20 despite healthy grafts and no ocular comorbidities. Reasons for this remain unclear, with theories including anterior stromal changes, differences in graft thickness and regularity, induced high order aberrations, and the nature of the graft-host interface. Newer iterations of endothelial keratoplasty such as thin manual DSEK, ultrathin DSAEK, and DMEK have achieved rates of 20/20 acuity of approximately 50%, comparable to modern cataract surgery , and it may be that a ceiling exists, particularly in the older age group of patients. Establishing the relative contribution of the factors that determine visual quality following endothelial keratoplasty will help drive further innovation, optimising visual and patient-reported outcomes while improving surgical efficacy and safety.

“…18 Specifically, all the DSEK procedures utilized temporal wounds, 5 to 6 mm corneal incisions, sheets glide push-in, and 10-minute air injection of >35 mm Hg IOP, then 80% air fill for 24 hours. In addition, similar techniques were utilized in terms of suturing in PK by all surgeons.…”

“…According to a study by Sarnicola et al, BB provides the highest rate of DM exposure [4] . In a major review of lamellar corneal transplantation, Arenas et al stated that the BB technique 'is a faster and reliable way of baring the DM' [15] . A suction trephine is used to perform a partial thickness corneal trephination at a depth of about 60-80%.…”

Deep anterior lamellar keratoplasty (DALK) is currently the procedure of choice to restore transparency and curvature in corneal stromal diseases with a healthy endothelium. Preserving the endothelium avoids endothelial rejection and provides a good and stable endothelial cell count, allowing good long-term graft survival. Several surgical techniques have been proposed over the last years, the most common of which include layer-by-layer manual dissection, hydrodissection, viscodissection, big bubble (needle or cannula) and air-viscobubble. Descemet's membrane rupture represents the most common complication, even in expert hands. The penetrating keratoplasty conversion rate gradually decreases as surgeons become more experienced and learn to manage Descemet's membrane ruptures. Being able to repair the ruptures would increase the success of DALK and allow patients to benefit from all of its advantages. a b cGüell JL (ed): Cornea.
