Frank Bochmann, Jörg Strümer
PURPOSE: A subluxation or dislocation of the intraocular lens (IOL) is a well-known complication after cataract surgery in patients with pseudoexfoliation syndrome (PEX). Capsular tension rings (CTR) are frequently used to prevent postoperative complications caused by zonular weakness. Here we present a series of 7 cases, 2 with intermittent and 5 with acute angle closure caused by a combination of PEX-associated zonular weakness and a resulting unstable capsular bag-CTR-IOL complex. MATERIALS AND METHODS: We describe the typical clinical course with elevated intraocular pressure, myopic shift, and shallowing of the anterior chamber in 7 patients with a new type of secondary angle closure...

An indoor-only, 5-year-old, spayed female domestic shorthair cat presented for an ophthalmic examination of the left eye. An intraocular tumor with secondary glaucoma and blindness was diagnosed; the globe was enucleated and sent for histopathological examination. Gross examination revealed a solid white mass filling the entire vitreous space and replacing the iris and ciliary body. The lens and retina appeared to be similarly replaced by the neoplasm. Histological examination revealed a complete loss of the internal ocular structures, with a ruptured capsule as the only remnant of the lens within an extensive malignant mesenchymal neoplastic cell proliferation...

We describe a surgical technique for secondary stabilization of a bag-in-the-lens intraocular lens (BIL IOL) using 2 modified bean-shaped ring segments in cases of zonular dehiscence associated with pseudophakodonesis. The first modified bean segment is anchored in the sulcus with a suture to the sclera in the area of maximum zonular dehiscence, and the second segment is implanted in the opposite sulcus area. Both segments are placed in the BIL IOL interhaptic groove. The segments stabilize and center the BIL IOL by creating an artificial zonule that provides the necessary extra support for the IOL...
