The purpose of this study is to demonstrate the feasibility of DALK using a decellularized corneal matrix obtained by HHP methodology. Porcine corneas were hydrostatically pressurized at 980 MPa at 10°C for 10 minutes to destroy the cells, followed by washing with EGM-2 medium to remove the cell debris. The HHP-treated corneas were stained with H-E to assess the efficacy of decellularization. T...
Purpose: To describe the characteristics of donor and recipient, indications, surgical techniques, survival results obtained from patients with corneal transplants performed at Fundación Oftalmológica Nacional (FUNDONAL) between 2010 2017.Methods: Descriptive, observational study. Medical records who underwent transplantation were reviewed. Demographic data, surgery indication, technique, graft...
PURPOSE To determine the optimal conditions for enhancing corneal allograft survival by oral immunization with donor-specific alloantigens. METHODS CB6F1 mice were orally immunized with various doses of C3H/Hej corneal epithelial and endothelial cells before receiving orthotopic C3H/Hej corneal allografts. Paraformaldehyde-fixed corneal cells were compared with viable corneal cells for their ...
As the primary refractive surface of the eye, clarity of the cornea is essential for optimal visual acuity. Many disease processes can irreversibly disrupt corneal clarity requiring corneal transplantation to restore visual function. The most common indication for corneal transplantation is opacification from corneal edema. Corneal edema arises from dysregulation of fluid homeostasis in the cor...
AIM/BACKGROUND The public health significance of corneal transplantation in dealing with corneal blindness in the developing world would depend upon the survival rate of transplants. This study was done to analyse the survival rate of corneal transplants in a large series in India, and to evaluate the influence of various risk factors on transplant survival. METHODS The records of a series of...
Abstract Background: Although corneal graft may be rejected by the immune system of the recipient it remains as the most successful operation as compared to transplantation of other tissues. Since most patient do not reject the grafts, those who do are in the minority. This study was carried out to assess the usefulness of the cure frailty model for determining the significance of risk facto...
