目的：评价Trulign环形人工晶状体（IOL）治疗成人白内障的安全性和有效性。环境：在美国有八家私人诊所，在加拿大有一家。设计：前瞻性随机单盲多中心研究。方法：年龄相关性白内障患者需要16.00 ~ 27.00屈光度(D)的球形人工晶状体，术后预计散光为0.83 ~ 2.50 D。在最低晶状体范围内（术后预计散光为0.83 ~ 1.32 D）的眼睛按1:1的比例随机分为1.25 D的环形人工晶状体组和非晶状体调节型人工晶状体（Crystalens）对照组。结果：toric 1.25 D组绝对柱体减少率显著高于对照组（P < 0.05）
PURPOSE: To evaluate the safety and effectiveness of the Trulign toric intraocular lens (IOL) in adults with cataract.SETTING: Eight private practices in the United States and 1 in Canada.DESIGN: Prospective randomized single-masked multicenter study.METHODS: A toric IOL (1.25 D, 2.00 D, or 2.75 D, determined by a toric calculator) was implanted in eligible patients with age-related cataract requiring a 16.00 to 27.00 diopter (D) spherical IOL power and with a predicted postoperative astigmatism of 0.83 to 2.50 D. Eyes within the lowest cylinder range (predicted postoperative astigmatism 0.83 to 1.32 D) were randomized in a 1:1 ratio between the 1.25 D toric IOL group and the nontoric accommodating IOL (Crystalens) control group.RESULTS: The toric 1.25 D group had a statistically significantly greater percentage reduction in absolute cylinder (P
