Pupilloplasty by radiofrequency diathermy

Abstract

Purpose: 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.

Methods: 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.

Results: 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.

Conclusion: 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.
