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.
