Several methods have been reported to treat pupil deformities. However, there are some disadvantages to these methods. Here, we introduce the new technique of pupilloplasty.
We retrospectively collected five patients who underwent pupilloplasty by radiofrequency diathermy (RFD) in eyes with acorea or a severe pupillary fibrous membrane. The RFD tip was inserted into the anterior chamber after injection of an ophthalmic viscosurgical device (OVD). It was then used to resect the iris and fibrous membrane around the pupillary centre to restore a centred and round pupil.
No obvious bleeding was observed during resection of the iris or fibrous membrane with the RFD technique. All cases were successfully treated, and pupil transparency was restored.
We introduced a new technique of pupilloplasty by RFD that is easily manageable, reduces bleeding, and is suitable for most types of pupillary seclusion, especially for acorea and severe pupillary fibrous membrane.
已有多种方法用于治疗瞳孔变形。然而，这些方法都存在一些缺点。在此，我们介绍一种新的瞳孔成形术。
我们回顾性收集了 5 例因虹膜睫状体炎或严重瞳孔纤维膜导致瞳孔变形而接受射频热疗（RFD）瞳孔成形术的患者。在眼内注入眼用黏弹剂（OVD）后，将 RFD 探头插入前房，然后用其切除瞳孔中心周围的虹膜和纤维膜，以恢复瞳孔居中、圆形。
用 RFD 技术切除虹膜或纤维膜时，未见明显出血。所有病例均成功治疗，瞳孔透明度恢复。
我们介绍了一种新的 RFD 瞳孔成形术，该技术易于操作，减少出血，适用于大多数类型的瞳孔闭锁，尤其是虹膜睫状体炎和严重瞳孔纤维膜。
