A NEW CORNEA-MARKING DEVICE FOR PENETRATING KERATOPLASTY AND REFRACTIVE CORNEAL PROCEDURES

In penetrating keratoplasty, postoperative astigmatism is determined b y a number of factors, including adaptation of wound edges, mode of tr ephination of both donor and patient cornea and, last but not least, s uture techniques. We would like to introduce a new cornea-marking devi ce 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 t his device was used is under way.
