We report 4 cases of silicone intraocular lens (IOL) opacification (SI-40NB, Allergan Inc.) in patients who had phacoemulsification between April and June 2003. The opacification was observed on the first postoperative day in all cases. The appearance of the silicone IOLs ranged from milky gray to a yellow hue and affected the entire optical component homogeneously. The patients did not complain about their vision, and visual acuity was only slightly affected; 3 of the 4 patients had a best corrected visual acuity of 20/30, and no anterior chamber reaction was observed. Contrast sensitivity was reduced in all cases. Careful scrutiny of medical histories failed to reveal factors that might have predisposed the patients to IOL opacification.
我们报告了2003年4月至6月期间接受超声乳化白内障吸除术的患者中发生的4例硅凝胶人工晶状体（IOL，型号SI-40NB，爱尔康公司）混浊病例。所有病例均在术后第一天观察到混浊。硅凝胶人工晶状体的外观从乳灰色到黄色不等，整个光学部件均受到均匀影响。患者未诉视力问题，视力仅受到轻微影响；4例患者中有3例最佳矫正视力为20/30，未观察到前房反应。所有病例的对比敏感度均降低。仔细查阅病史未发现可能使患者易发生人工晶状体混浊的因素。
