Zusammenfassung

Hohe Astigmatismen nach perforierender Keratoplastik erschweren trotz klaren Hornhautransplantates die optische Rehabilitation des Patienten.

In der frühen postoperativen Phase nach perforierender Keratoplastik kann durch eine Nahtkorrektur („suture adjustment“) die Spannung einer einfach fortlaufenden Naht so umverteilt werden, daß der Astigmatismus reduziert wird. Wir führten ein „suture adjustment“ bei 22 Patienten 1–3 Monate nach perforierender Keratoplastik durch. Der präoperativ ermittelte Astigmatismus von durchschnittlich 9,3 ± 2,7 dpt wurde postoperativ signifikant (p<0,0001) auf 4,1±2,3 dpt reduziert. Der Nachbeobachtungszeitraum umfaßte 5–22 (11,27 ± 4,66) Monate. Operative Komplikationen wie Fadenruptur oder Keratitis wurden nicht beobachtet. Bei 6 Patienten konnte bereits der Faden 12–18 Monate nach perforierender Keratoplastik entfernt werden. Hier blieben die Astigmatismuswerte stabil. Die frühe postoperative Astigmatismuskorrektur mittels „suture adjustment“ stellt eine verläßliche und sichere Methode dar.

Summary

High astigmatism is a frequent complication of penetrating keratoplasty. Visual rehabilitation is often poor despite successful corneal transplantation. A reduction of high astigmatism can be performed by suture adjustment in the early postoperative period after penetrating keratoplasty. Twenty-two patients with an average astigmatism of 9.3 ± 2.7 diopters underwent suture adjustment 1–3 months after penetrating keratoplasty, which was done with a running nylon suture. Following adjustment astigmatism was significantly (p<0,0001) reduced to 4,1 ± 2,3 diopters. No adverse effects or relapses were noted. The follow-up period was 5–22 (11.27 ± 4.66) months. After suture removal in six patients the reduced astigmatism was stable. Early post-operative suture adjustment constitutes a reliable technique in corneal astigmatism reduction after penetrating keratoplasty.
