人工晶体设计的不断改进和手术技术的不断丰富,使白内障术后能获得较为满意的效果。但临床研究及对眼球摘除术后的人眼进行组织学检查发现,几乎所有植入人工晶体的人眼均存在不同程度的异物反应性炎症。在某些病例,急性炎症反应发展成为术后持续性葡萄膜炎。对此瑞典试制成一种新型人工晶体。用一种嫁接技术对聚甲基丙烯酸甲酯(PMMA)进行表面处理,使肝素特异性地与聚合物表面结合,更具亲水性。离体实验表明肝素表面处理的人工晶体能降低人粒细胞的活性,降低血小板的粘着力和人成纤维细胞的增生。本文报道了由多医疗中心,采用双盲法并随访了一年的二组病例的比较结果。来自世界10个医疗中
The continuous improvement of intraocular lens design and the continuous enrichment of surgical techniques have made cataract surgery more satisfactory. However, clinical studies and histological examination of the human eye after enucleation have found that almost all of the human eyes implanted with intraocular lens have varying degrees of foreign body reactive inflammation. In some cases, the acute inflammatory response develops into persistent uveitis. Sweden this trial made a new type of artificial crystal. Polymethylmethacrylate (PMMA) is surface treated with a grafting technique to bind heparin specifically to the polymer surface, making it more hydrophilic. In vitro experiments showed that heparin surface treatment of intraocular lens can reduce the activity of human granulocytes, reducing platelet adhesion and proliferation of human fibroblasts. This article reports the results of a comparison of two groups of patients enrolled in a multi-center, double-blind, and one-year follow-up. 10 medical treatments from the world
