穿透性角膜移植治疗外伤性角膜病变的临床观察

目的:探讨穿透性角膜移植术治疗外伤性角膜病变的临床疗效。方法:对17例外伤性角膜病变施行穿透性角膜移植术,2例行穿透性角膜移植术联合小梁切除术,观察术后角膜植片及视力变化。结果:随访6~18(平均11.2)mo,术后临床症状明显缓解或消失,植片透明率为84%。视力较术前提高,其中矫正视力0.05以上16例;术后继发性青光眼5例,内皮型排斥反应4例。结论:穿透性角膜移植术是治疗外伤性角膜病变的一种有效的手术方式,其主要并发症为继发性青光眼和角膜移植排斥反应。

Clinical observation of penetrating keratoplasty for treatment of traumatic keratopathy

AIM:To evaluate the effect of penetrating keratoplasty on treatment of traumatic keratopathy.METHODS:Seventeen cases of traumatic keratopathy were treated by penetraing keratoplasty,while 2 cases underwent penetrating keratoplasty combined with trabeculectomy.Corneal grafts and the changes in visual acuity were observed after operation.· RESULTS:Corneal grafts and the changes in visual acuity were followed up for 6 to 18 months(11.2 months on average).All the clinical symptoms remitted or disap-peared,the buttons were transparent and postoperative visual acuity was improved.Sixteen eyes had a corrected visual acuity of 0.05 or better and 4 eyes had 0.2 or better.Five cases of secondary glaucoma and 4 cases of endothelial rejection were found. CONCLUSION:The penetrating keratoplasty for treatment of traumatic keratopathy was effective.Postoperatively,the primary complications are glaucoma and graft rejection.
