Hamed Hatami-Marbini, Sandeep M Jayaram
The UVA/riboflavin collagen crosslinking (CXL) is one of the treatment procedure for stopping the progression of keratoconus. The inclusion criterion for this procedure is a minimum corneal thickness of 400 μm, which is not often met in patients with advanced keratoconus. Preoperatively swelling of thin corneas was shown to stabilize the keratectasia without any postoperative endothelial damage. Recently, we have shown that swelling porcine corneas prior to the CXL treatment had no significant effect on the resulting improvement in their tensile properties...

We present a case of decreased vision due to the presence of retained Descemet membrane (DM) following Descemet stripping automated endothelial keratoplasty (DSAEK) and penetrating keratoplasty (PKP). A 78-year-old male presented postoperatively from PKP after previous failed DSAEK with retained DM. We present a unique technique for combined surgical resection using bimanual vitrectomy and forceps excision assisted by triamcinolone acetonide for membrane visualization. Histopathological evaluation confirmed incomplete DM removal during the PKP...

Intraocular lens (IOL) opacification is rare but may occur after non-Descemet stripping automated endothelial keratoplasty (n-DSAEK) or intravitreal air injection after pars plana vitrectomy (PPV). We reported two cases of IOL opacification within the pupillary region. Chart was retrospectively reviewed. The predisposing factors and the visual acuity were analyzed. The opacification was evaluated by anterior segment optical coherence tomography (AS-OCT). A 68-year-old healthy woman with pseudophakic bullous keratopathy underwent uneventful n-DSAEK in the right eye...

REVIEW
V Kocaba, O Damour, C Auxenfans, C Burillon
Endothelial keratoplasty is currently the preferred method for the treatment of endothelial dysfunctions and dystrophies. Descemet Membrane Endothelial Keratoplasty (DMEK), described by Gerrit Melles in 2006, is performed by selectively replacing the damaged endothelium with a healthy counterpart. It leads to a faster visual recovery and better refractive outcomes with a limited risk of rejection compared to Descemet's Stripping Automated Endothelial Keratosplasty (DSAEK), which includes a thin stromal layer...

Purpose: Descemet's stripping automated endothelial keratoplasty (DSAEK) is more difficult in hypotonic eyes with filtering bleb, due to the difficulties in elevating the intraocular pressure (IOP). We report a new method that uses ophthalmic viscoelastic devices (OVDs) to achieve good graft adhesion. Case Presentation: We performed modified DSAEK surgery on 2 eyes of 2 patients, who had previously undergone a trabeculectomy. Both eyes had functioning filtering blebs; the IOP was lower than 10 mmHg without medication...
