Iridoschisis is a rare condition frequently associated with age-related cataract. Phacoemulsification can be difficult to perform in these eyes, as the detached iris fibrils that are typically present free float in the anterior chamber and are attracted to the phaco tip and the irrigation/aspiration handpiece port. We describe a technique for performing phacoemulsification in eyes with iridoschisis. In this technique, iris fibrils are held in place by 2 ophthalmic viscosurgical devices (OVDs) that are injected into the inferior portion of the anterior chamber. An elliptical capsulorhexis is made and limited to the superior half of the pupil for additional stability of the anterior chamber during surgery. The nucleus is chopped with a phaco chopper and a bent-tip, 22-gauge needle. Most of the phacoemulsification is performed under the anterior capsule. The iris comes into contact with the OVDs only and has no mechanical trauma.
虹膜劈裂症是一种罕见病症，常与年龄相关性白内障相关。在这些眼睛中进行超声乳化手术可能会很困难，因为通常存在的分离虹膜纤维在前房内自由漂浮，并被超声乳化头及灌注/抽吸手柄端口吸引。我们描述了一种在患有虹膜劈裂症的眼睛中进行超声乳化手术的技术。在该技术中，通过注入到前房下部的2种眼科粘弹剂（OVD）将虹膜纤维固定在位。制作一个椭圆形连续环形撕囊，并将其限制在瞳孔上半部分，以便在手术过程中增加前房的稳定性。使用超声乳化劈核刀和22号弯尖针切碎晶状体核。大部分超声乳化操作在前囊膜下进行。虹膜仅与OVD接触，没有机械性损伤。
