In a prospective controlled trial 290 consecutive patients were randomly allocated a polymacon or a poly(methyl methacrylate) (PMMA) intraocular lens. Early Treatment of Diabetic Retinopathy Study (ETDRS) acuity charts gave similar results with both lenses. However Pelli-Robson contrast sensitivity charts gave a better result with PMMA lenses. Polymacon lenses appeared to remain free of any adhesions after implantation raising the question of long term stability. Four patients experienced problems related to this, three involved total lens dislocation. Seven patients developed early 'fibrin' membranes coating the polymacon lens, of which three were florid.
在一项前瞻性对照试验中，290例连续患者被随机分配植入聚甲基丙烯酸甲酯（PMMA）人工晶状体或聚马康（polymacon）人工晶状体。糖尿病视网膜病变早期治疗研究（ETDRS）视力表显示，两种人工晶状体的结果相似。然而，佩利-罗布森（Pelli-Robson）对比敏感度表显示，PMMA人工晶状体的结果更好。聚马康人工晶状体植入后似乎没有任何粘连，这引发了其长期稳定性的问题。4例患者出现与此相关的问题，其中3例发生人工晶状体完全脱位。7例患者早期出现覆盖聚马康人工晶状体的“纤维蛋白”膜，其中3例较为严重。
