Patch grafting is a procedure employed to address large corneoscleral perforations or impending ones where tectonic stability of the globe is at stake. It is usually done using corneal trephines, the size of which depends on the largest dimension of corneal pathology, often necessitating a large area of dissection. Instead of trephination to ensure the right fit of the excised tissue, we thought that templates made from surgical drape can serve a similar purpose, which is exemplified in this article.
