目的探讨自制的PMMA-硅胶夹持型人工角膜植入碱烧伤兔眼角膜的手术方法和疗效。方法建立兔眼碱烧伤模型:将PMMA-硅胶夹持型人工角膜植入碱烧伤后形成白斑的兔眼角膜,观察6个月。结果人工角膜手术操作顺利,术后1只实验兔眼出现了眼内炎,人工角膜脱出,另1只兔术后7周死亡,余3只兔眼在观察期内未见角膜组织溶解、房水渗漏、青光眼、感染或人工角膜前后膜增生等并发症,人工角膜稳定在位并保持透明。结论本实验自制的PMMA-硅胶夹持型人工角膜,手术操作简单,术中及术后并发症较小,似有实际临床应用价值。

Objective To discuss the operative methods and clinical effect of clipped PMMA-silicone keratoprosthesis implanted into alkali - burned rabbit' s corneas. Methods 1. To establish the models of the alkali-burned rabbit's corneas; 2. To implant the clipped PMMA-silicone keratoprosthesis into the alkali-burned rabbit' s corneas. Results The process of the keratoprosthesis operation is successful; One of the keratoproshtesises prolapsed because of the endophthalmitis, there were no severe complications in the rest of 3 corneas, such as corneal dissolve, aqueous humor leakage, glaucoma, infection or the former &rear proliferous membranes, the keratoprothesis kept transparent. Conclusion The self-made PMMA-silicone clipped keratoprothesis which is designed logically and operated easily, with fewer intraoperative and postoperative complications, will be useful to clinical practice.
