Pars plana vitrectomy for posterior surface calcification in a silicone intraocular lens in asteroid hyalosis – a report of mistaken identity?

Abstract

Paul G Rainsbury,1 Jonathan Lochhead2 1Eye Unit, Queen Alexandra Hospital, Cosham, Portsmouth, Hants, UK; 2Eye Unit, St Mary’s Hospital, Newport, Isle of Wight, UKMehta et al recently reported removal of dystrophic calcification on the posterior surface of a silicone intraocular lens (IOL) in a patient with asteroid hyalosis.1 In this case the authors used pars plana vitrectomy (PPV) to successfully remove calcified deposits. We have recently tried unsuccessfully to use PPV to treat an 86 year old patient with calcification of a silicone IOL in the presence of asteroid hyalosis. We chose to avoid IOL exchange due to a history of Fuchs endothelial dystrophy and glaucoma in the left eye, and a failed corneal graft in a rubeotic eye on the right. Our patient did not have an intact posterior capsule having been treated with Nd:YAG capsulotomy 2 years previously, before the calcification occurred.View original paper by Mehta and colleagues.
