植床带周边后板层的大植片穿透性角膜移植术临床观察

Clinical observation of penetrating keratoplasty implemented by using back ply of large corneal graft in botanic bed

目的评价植床带周边后板层的大植片穿透性角膜移植术的临床疗效。方法24例24眼用植床带周边后板层的大植片穿透性角膜移植术为改良组,57例64眼用常规大植片穿透性角膜移植术为对照组,两组对照观察。结果1、视力:两组无差别。2、并发症:改良组术后浅前房1眼(4.2%)、虹膜前粘连2例(8.3%)、继发青光眼2例(8.3%);对照组术后浅前房22眼(34.4%)、虹膜前粘连21例(32.8%)、继发青光眼22例(34.4%)。改良组并发症比对照组低(P<0.05)。结论植床带周边后板层是大植片穿透性角膜移植术有效的改良方法。

Objective To improve the traditional penetrating keratoplasty （PKP） by new methods applying the back ply of large peripheral lamina in botanic bed. Methods 81 cases （88 eyes） had been taken the corneal graft with corneas of physical diameter greater than 9 millimeters. 24 cases （24 eyes） usd the new methods and others with traditional PKP. Results Within the 24 cases （24 eyes） treated by the new methods, 1 （4.2%） eye had shallow anteroom, 2 （8.3%） cases had anterior synechia, 2 （8.3%） cases had consequent glaucoma. Within other 57 cases （64 eyes） treated by traditional PKP, 22 （34.4%） eyes had shallow anteroom, 21 （32.8%） cases had anterior synechia, 22 （34.4%） cases had consequent glaucoma. Compared with the occurrence rate of postoperative glaucoma of the cases treated by traditional PKP, the counterpart for the new methods was significantly lower. Conclusion The new methods have been practically proved to be an effective improvement of the traditional PKT.
