Clinical Data
The presented study is an observational case series. The David J. Apple International Laboratory for Ocular Pathology at the Department of Ophthalmology of the University of Heidelberg received 10 hydrophilic IOLs that were explanted owing to IOL opacification after PPV. Explanting surgeons (G.U.A.: 2 IOLs and S.B.: 8 IOLs) provided all available information on the cases. Relevant clinical data were evaluated and numeric values are given as median and range. All 10 specimens were hydrophilic
Patient History
The IOLs were implanted between January 2002 and May 2016. Three patients were female and 6 male. The patients' mean age at crystalline lens replacement was 54 (range 18–77) years. In all cases patients received PPV owing to retinal detachment. Six patients underwent simultaneous phacoemulsification with IOL implantation and PPV in combined surgery. The remaining 4 patients received PPV from 3 months to 13 years after initial phacoemulsification and IOL implantation. Gas was used in at least 1
Discussion
This analysis included 10 explanted IOLs that were exchanged for new lenses owing to secondary IOL calcification following PPV. In 8 cases calcification was found just beneath the anterior central pupillary area of the IOL. In the remaining 2 cases IOL opacification was located underneath the posterior surface (Cases 1 and 7). Both patients had received posterior capsulotomy during retinal surgery. The authors could not identify a precise causative factor(s) in opacification of the studied
