Description Shaped corneal transplantation surgery is the preferred modality of treatment in peripheral corneal perforations for restoration of tectonic integrity.1 Various techniques have been described to fashion an appropriated size and shaped graft. The trephine-based techniques require multiple combinations of trephines.2 3 Among the free-hand techniques, the copy and fix method requires placement of the donor rim directly on the host defect, thereby increasing the possibility of endothelial cell loss and infection.4 The prick and print technique involves the use of a transparent sheet to create a stencil, but is unsuitable for elevated or deeply excavated lesions as the sheet does not conform to the contours of the cornea.5 In addition, the internal technique of sutureless pull through mini-DSAEK has also recently been described.6 A material that conforms with the corneal curvature would provide a better stencil, thereby reducing the postoperative astigmatism in addition to being a ‘no-touch’ technique. Bandage contact lens provides a possibly better alternative to a transparent sheet or the direct placement of donor tissue on the host defect to create a stencil.
