Background: The results of penetrating keratoplasty in two centres for cornea transplantation were investigated with regard to the following parameters: the t rephine system used, the origin of the donor cornea, the influence on the postop erative astigmatism and other aspects. Patients and Methods: The retrospective c linical investigation reports about the results of 186 patients with penetrating keratoplasty from the University Eye Hospital of Halle and 204 patients from th e Eye Clinic of the Helios hospital Aue. Results: Three trephine systems have be en used: the Hessburg-Barron trephine, the guided trephine system (gTS) and the Asmotom device. There were no significant differences between them concerning v isual acuity after 12 months postoperatively. The results were highly significan tly better (P=0.003 Halle; P=0.001 Aue) when using larger diameters of the treph ine (7.5 mm and 8.0 mm). The origin of the donor cornea (“fresh”cornea from a deceased subject or organ cultivated cornea from a cornea bank) had no influence on visual outcome after twelve months (P > 0.8). There were less wound dehiscen ces using the double running suture in comparison with other techniques (P=0.05) . The removal of suturing material was not effective in reducing postoperative a stigmatism (P > 0.11). There was no increase in astigmatism when leaving the sut ures in situ (P > 0.25). Conclusions: generally, each of the three trephine syst ems can be recommended for clinical use. The trephination should be done with tr ephine diameters of 7.5 mm or 8.0 mm. A timely operation guarantees better visua l acuity at one year postoperatively.

自体同侧旋转式穿透性角膜移植术:一种预防Peter异常症中严重不可逆弱视的早期手术方法(德)

Puprose: it is a challenge to prevent irreversible amblyopia in infants suffering from Peters anomaly. in some cases of centrally located corneal opacifications an optical sector iridectomy can not lead to a clear optical axis. The homologous penetrating keratoplasty as early surgical procedure has shown an extremely poor outcome with a high risk of irreversible graft failure. we report on the autologous ipsilateral rotating penetrating keratoplasty in an eight- week- old infant suffering from Peters anomaly. Patients: An autologous ipsilateral rotating penetrating keratoplasty was performed in an eight- week- old infant suffering from Peters anomaly to prevent irreversible amblyopia. Results: After a follow- up time of 8 months we saw a clear graft within the optical axis without any complications in wound healing. we removed the single sutures two months after keratoplasty. Postoperative astigmatism could be corrected first by fitting a special nursery contact lens and after reduction of astigmatismbecause of suture removalwe fitted special nursery glasses. The intraocular pressure remained within the normal range during the follow- up period. Conclusion: The autologous ipsilateral rotating penetrating keratoplasty should be considered superior to homologous keratoplasty in infants withPeters anomaly if sector iridectomy is not advisable because of a central corneal opacification. Resulting high refractive errors can be successfully corrected by special contact lens fitting or by nursery glasses.
