Abstract Details

Purpose:

Explanted intraocular lenses (IOLs) from eyes that had received a sulcus supported supplementary IOL in addition to the primary posterior chamber lens were analysed.

Setting:

The David J. Apple International Laboratory for Ocular Pathology, Heidelberg, Germany.

Methods:

Analysis of eight opacified IOLs, explanted from seven polypseudophakic eyes (with a sulcus supported supplementary IOL in addition to a capsule-fixated lens) that were sent to our laboratory. The lenses were explanted due to opacification of the primary IOL (three cases), the supplementary IOL (three cases) or both (one case). Analyses included light microscopy, histological staining, scanning electron microscopy, energy dispersive X-Ray spectroscopy. Furthermore, crystal analysis was performed using transmission electron microscopy and diffraction measurements.

Results:

In all opacified IOLs, deposition of a thin layer of calcium phosphate that had accumulated just underneath the optical surface of the IOL caused the opacification. All opacified lenses were made from hydrophilic acrylic material. Different secondary procedures were performed, some that are known to facilitate secondary IOL calcification like pars plana vitrectomy or descemet stripping endothelial keratoplasty.

Conclusions:

For the first time, we report on IOL calcification in eyes with polypseudophakia. In some cases the primary lens was calcified, in others the supplementary IOL, or even both. Patient history after implantation of the IOLs differed between the cases. Calcification lead to deteriorated vision that resulted in explantation of the lens. Crystal analysis revealed the composition deposits.
