One hundred twelve patients scheduled for uncomplicated cataract removal were randomly assigned to receive a STAAR Elastimide three-piece foldable intraocular lens inserted through a 4.0 mm incision or a STAAR poly(methyl methacrylate) (PMMA) lens inserted through a 7.0 mm incision. The same surgeon performed all surgeries using identical techniques, except for incision size and number of sutures. Patients receiving Elastimide lenses had significantly better uncorrected visual acuity postoperatively than patients receiving PMMA lenses and also had significantly less keratometric cylinder, surgically induced cylinder (vector method), and refractive cylinder. The Elastimide foldable lens offers the advantages of small incision surgery for patients who require a three-piece lens.
112名计划接受单纯白内障摘除术的患者被随机分配，分别接受通过4.0毫米切口植入的STAAR Elastimide三片式可折叠人工晶状体，或通过7.0毫米切口植入的STAAR聚甲基丙烯酸甲酯（PMMA）晶状体。除切口大小和缝线数量外，同一位外科医生采用相同技术进行所有手术。接受Elastimide晶状体的患者术后裸眼视力明显优于接受PMMA晶状体的患者，并且角膜散光、手术源性散光（矢量法）和屈光性散光也明显更少。对于需要三片式晶状体的患者，Elastimide可折叠晶状体具有小切口手术的优势。
