Ripasudil for Enhanced Corneal Clearing Following Descemet Membrane Endothelial Keratoplasty in...

Fuchs Endothelial Dystrophy

Recently, published literature has reported that performing a descemetorhexis in combination with topical Rho kinase (ROCK) inhibitor therapy was successful in clearing edematous corneas in patients with Fuchs Endothelial Corneal Dystrophy. Ripasudil hydrochloride hydrate( Glanatec ophthalmic solution 0.4%), a potent ROCK inhibitor, has been approved in Japan since 2014 for ocular use in the treatment of glaucoma. Ripasudil acts as an IOP-lowering drug by affecting aqueous outflow through the trabecular meshwork and Schlemm's canal. The goal of this study is to test the potential benefits of Ripasudil therapy administered after Descemet Membrane Endothelial Keratoplasty (DMEK) surgery. We believe that performing a standard DMEK surgery in combination with Ripasudil treatment in patients with Fuchs Endothelial Corneal Dystrophy could accelerate endothelial cell healing and clear edematous corneas faster, with less post-operative complications.

DSAEK- Postoperative Positioning and Transplant Dislocation

Corneal TransplantationDescemet Stripping Automated Endothelial Keratoplasty3 more

Corneal transplant is a surgical procedure where a damaged or diseased cornea is replaced by donated corneal tissue (the graft) in its entirety (penetrating keratoplasty) or in part (lamellar keratoplasty). One type of lamellar keratoplasty is DSAEK (Descemet's Stripping Automated Endothelial Keratoplasty), where only the damaged posterior section of the cornea is replaced. The purpose of this study is to investigate how immediate postoperative positioning of the patient affects the dislocation rate of the corneal graft. Since this is a new surgical method, little scientific documentation has been published in this area.

Assessment of Corneal Graft Attachment in Patients With Fuchs Endothelial Corneal Dystrophy Following...

Fuchs' Endothelial Dystrophy

Fuchs endothelial corneal dystrophy (FECD) is a progressive disease characterized by the loss of endothelial cells, thickening of Descemet's membrane and deposition of extracellular matrix in the form of guttae. This result in failure of the endothelium to support corneal deturgescence leading to corneal edema. Affected patients complain about blurred vision at early stages of the disease which can progress to blindness. The pathophysiology of the disease is still unclear, but several studies point towards a genetic susceptibility. Additional risk factors that have been identified are female sex, smoking and older age. While for a long time penetrating keratoplasty (PKP) was the only therapy available for affected patients, in the recent years less invasive methods such as descemet's membrane endothelial keratoplasty (DMEK) have been developed. In DMEK, only the Descemet's membrane and the endothelium is removed and replaced with the corresponding parts from a donor's cornea. For FECD, this brings the advantage that only the diseased part of the cornea is replaced. Graft detachment has been identified as the main complication following DMEK. In the investigators' study, an ultra high resolution OCT system will be used to detect graft detachment in patients with FECD after DMEK. With this technique, even small detachments can be visualized. The area of graft detachment will be evaluated at predefined time points after surgery and correlated to visual acuity. A follow-up of one year will be performed in order to investigate the predictive value of graft adherence status at several time points for visual outcome.

Immunosuppression During Penetrating Keratoplasty, Using a Subconjunctival Implant Releasing Dexamethasone...

KeratoconusFuchs' Endothelial Dystrophy1 more

Immune rejection episodes after penetrating keratoplasty occur in 30% of patients and constitute one of the main factors reducing graft survival. They mainly occur during the first 18 months. Prevention usually relies on a topical treatment with dexamethasone or prednisolone for standard risk patients. Eye drops are instilled three times a day during at least 3 months then tapered. OZURDEX is an absorbable small implant that releases a total of 700 micrograms dexamethasone during several months. It is indicated for intravitreal injection to treat macular edema. The investigators hypothesized that this implant could be used after subconjunctival injection during corneal graft, to prevent immune rejection and avoid repeated eyedrop instillations.

Evaluation of the Efficacy of Descemet Membrane Transplantation for the Treatment of Fuchs' Endothelial...

Fuchs' Endothelial Dystrophy

Fuchs Endothelial Dystrophy (FED) is a degenerative disease affecting the corneal endothelium. The current gold-standard for treatment of severe FED is endothelial keratoplasty, wherein a cadaveric Descemet's membrane / endothelium graft is transplanted. In this study, the investigators hypothesized that the transplantation of an acellular Descemet's membrane (i.e. Descemet Membrane Transplantation, 'DMT') may be equally efficacious in promoting recovery of endothelial function in this group of patients.
