title: A new cornea-marking device for penetrating keratoplasty and refractive corneal procedures.
abstract: In penetrating keratoplasty, postoperative astigmatism is determined by a number of factors, including adaptation of wound edges, mode of trephination of both donor and patient cornea and, last but not least, suture techniques. We would like to introduce a new cornea-marking device for use in keratoplasty and epikeratophakia. This device helps the surgeon to center the trephine and to perform a perfect double running torque-antitorque suture. Additional single sutures are not necessary. A study of postoperative astigmatism following operations in which this device was used is under way.
