Flexible nylon iris retractors are a useful adjunct to cataract surgery in cases of small pupil and subluxated lenses. A modification is presented of the standard application of iris hooks to retract the superior iris and support the inferior capsule during phacoemulsification in cases of iris coloboma with inferior zonular deficiency. Three iris hooks are applied to retract the iris, and 2 iris hooks are applied to the inferior capsule margin to support the crystalline lens in that quadrant. Clear corneal temporal phacoemulsification is then performed with adequate pupillary diameter and capsular support.
对于小瞳孔和晶状体半脱位的病例，柔性尼龙虹膜牵开器是白内障手术中有用的辅助工具。本文介绍了一种对虹膜钩标准应用的改良方法，即在下方悬韧带缺损的虹膜缺损病例中，在超声乳化过程中牵开上方虹膜并支撑下方晶状体囊。应用三个虹膜钩牵开虹膜，应用两个虹膜钩于下方晶状体囊边缘以在该象限支撑晶状体。然后在瞳孔直径足够和囊膜支撑良好的情况下进行颞侧透明角膜超声乳化。
