We implanted three types of intraocular lens (IOL) in 30 eyes each by small-incision surgery. They were: foldable acryl IOL, foldable silicone IOL and polymethylmethacrylate (PMMA) IOL. We evaluated the following items during three years after surgery: visual acuity, astigmatism, glare disability, contrast sensitivity, tilt and decentering of IOL, corneal endothelial population, aqueous flare and aftercataract. Eyes foldable IOLs were more excellent than PMMA IOLs regarding visual acuity, astigmatism and aqueous flare which are indices for the early postoperative period. PMMA and acryl IOLs were more excellent than silicone IOLs regarding decentration of IOL and aftercataract which are indices for the late postoperative period.
我们通过小切口手术在30只眼中分别植入了三种类型的人工晶状体（IOL）。它们分别是：可折叠丙烯酸酯人工晶状体、可折叠硅凝胶人工晶状体和聚甲基丙烯酸甲酯（PMMA）人工晶状体。我们在术后三年期间评估了以下项目：视力、散光、眩光障碍、对比敏感度、人工晶状体的倾斜和偏心、角膜内皮细胞数量、房水闪光和后发性白内障。在视力、散光和房水闪光这些术后早期指标方面，植入可折叠人工晶状体的眼比PMMA人工晶状体的眼更优。在人工晶状体偏心和后发性白内障这些术后晚期指标方面，PMMA和丙烯酸酯人工晶状体比硅凝胶人工晶状体更优。
