The Homburg Cross-Stitch Marker for Double-Running Sutures in Penetrating Keratoplasty.

Until now, the double-running cross-stitch according to Hoffmann used in penetrating keratoplasty (PKP) has been routinely carried out by simply using a sense of proportion. As a result, the estimation of the precisely defined entry and exit points of the sutures and, by extension, the success of the running cross-stitch suture was completely dependent on the practical experience of the surgeon. Therefore, we introduced the cross-stitch marker as a supporting instrument for PKP surgery. Description of the Homburg cross-stitch marker with an exact step-by-step guide on how the instrument is implemented while performing a PKP to mark entry and exit points for sutures including a video to demonstrate the use of this instrument. The new Homburg cross-stitch marker ensures the precise localisation of the entry and exit points of the suture. This new instrument allows inexperienced surgeons in particular to feel very confident when performing the running sutures. Surgeons with little experience can completely avoid using their still imprecise sense of proportion and significantly shorten the learning curve for this procedure. Thieme. All rights reserved.
