Summary: The main objective of this study is to determine the safety of Ex Vivo Cross Linking (CXL) of donor corneal tissue in participants who have undergone high-risk penetrating keratoplasty.

Summary: Descemet Endothelial Thickness Comparison Trial (DETECT) I is a multi-center, outcome assessor-masked, placebo-controlled clinical trial randomizing 160 patients in a 2x2 factorial design. The purpose of this study is to determine differences in visual outcomes between two types of corneal transplant surgeries, ultrathin Descemet stripping automated endothelial keratoplasty (UT-DSAEK) and Descemet...

Summary: Full-thickness corneal grafting (transfixing keratoplasty) is a tissue graft described at the beginning of the 20th century, which has remained technically unchanged for several decades. Around 900 transfixing keratoplasties are performed every year in France. This microsurgical procedure is intended for patients with severe corneal pathology that seriously impairs visual function, and for whom no...

Summary: The purpose of this study is to evaluate the pharmacodynamics, safety, and tolerability of DT-168 Ophthalmic Solution in pre-keratoplasty patients with Fuchs endothelial corneal dystrophy.

Summary: This is an open-label multicenter randomised controlled clinical trial with 2 parallel arms with a 1:1 ratio. Patients meeting the eligibility criteria will be offered to participate in the study during an ophthalmology consultation. If they agree, they are randomised into one of the 2 arms, surgery is scheduled, and baseline visual acuity, quality of life, patient satisfaction, pain level, and ce...

Summary: DMEK (Descemet Membrane Endothelial Keratoplasty) is a surgical technique used to treat primary or secondary corneal endothelial decompensation. At the Rothschild Foundation, as in many Western referral centers, DMEK is currently the surgical technique of choice for the treatment of primary or secondary corneal endothelial decompensation. Technically challenging, it is a relatively tedious surgery...

Summary: Some severe ocular burns or other rare ocular pathologies can be associated with a total loss of corneal epithelial stem cells (i.e. Limbal Stem Cell Deficiency - LSCD), which leads to cornea invasion by the conjunctiva and a subsequent opacification. When LSCD is total and bilateral, both eyes are affected leading to full blindness and a poor quality of life, with a paradoxical photophobia that m...

Summary: Over the past decade, the management of Fuchs' endothelial corneal dystrophy (FECD) and pseudophakic bullous keratopathy (PBK) has been revolutionized by the development of posterior lamellar keratoplasty techniques: DSAEK and DMEK. DSAEK (Descemet Stripping Automated Endothelial Keratoplasty) involves replacing the patient's endothelium and pathological descemetum with a descemetic endothelial gr...

Summary: The purpose of the study is to investigate whether there is a difference in BCVA in patients who receive one of the following two surgeries: intervention group (arm 1) cataract surgery alone and control group (arm 2) cataract surgery combined with removal of the diseased endothelial cells and the attached Descemet's membrane followed by transplantation of a healthy endothelial cell layer with atta...

Summary: Evaluate the well-being of patients and clinicl outcomes of the cornea after transplantation

Summary: The purpose of the study is to determine the safety and efficacy of brief intraoperative corneal endothelial graft incubation in plasma rich in growth factors (PRGF) for reducing postoperative endothelial cell loss.

Summary: This study is designed as a randomised multicentric parallel group pragmatic trial of Descemet Stripping Automated Endothelial Keratoplasty (DSAEK) versus Descemet Membrane Endothelial Keratoplasty (DMEK) in corneal endothelial decompensation. the purpose is to compare the clinical and patient reported outcomes of both therapies across a broad range of indications.
