Çekic ea, Removal of the intruding Miragel's Scleraal Buckle by Pars Plena Ultrasonic Fragmentation, Am J Ophthalmol 2005; 139:209-210  

Çekic ea melden dat zij een nieuwe operatietechniek, namelijk ‘pars plana ultrasonic fragmentation’ hebben toegepast om een het oog binnengekomen Miragel plombe te verwijderen zonder beschadiging van de retina.  

Purpose: To introduce a surgical approach for removing intruded scleral buckle resulting from Miragel's implant.
Design: Interventional case report.
Methods: After cutting and releasing scleral band externally, a pars plana Fragmatome was used to break up and aspirate pieces of the Miragel's implant that had grown into the eye, filling the vitreous cavity.
Results: The intruding Miragel's buckle was shaved to the plane of the retina without any complication. The retina was completely attached.
Conclusion: Use of ultrasonic fragmentation by a pars plana approach was effective in removing the intavitreally expanded buckling element without harming the retina.

Miragel's elements were used extensively for scleral indentation in the past. This material is no longer being used. Recently, because of late swelling complications of the material, Miragel's buckles have been subjected to removal. ¹ Both extrusion ¹ and intrusion ² of the Miragel's buckling elements have been reported. A newly described cryoextraction technique seems to be an appropriate method in cases of extrusion, because there are difficulties with grasping of the material, its brittleness, and its fragmentability. ³ To date, no surgical technique has been described to manage Miragel's buckles that have intruded into the vitreous. Here we introduce a new approach to remove an intravitreally intruded Miragel's implant by using pars plana ultrasonic fragmentation.

Using pars plana ultrasonic fragmentation, we were able to remove the Miragel's element from the intravitreal cavity while maintaining integrity of the retina and globe. Considering the probable increase in the number of Miragel's material intrusion cases in the future, the approach introduced here is expected to be useful for surgeons in managing such problems.
