Introduction
In cases of deep corneo-stromal ulceration surgical therapy is generally indicated. To improve healing, replace lost tissue and to achieve best possible tectonic and visual outcome autogenic, allogenic and xenogenic grafts and biomaterials have been used. Xenogenic grafts and biomaterials can be considered if autogenous or allogenous corneal grafting is not possible because of the extent of the defect or failing availability. Porcine bladder acellular matrix (ACell), amniotic membranes, bovine pericardium and swine intestinal submucosa (SIS) are biomaterials which have been applied already in treating canine corneal defects. Typically, these materials are anchored at the edge of the defect to the intact peripheral corneal tissue with sutures. The aim of this study was to demonstrate a modified technique not requiring corneal suturing and in that way making the procedure easier to perform.
