Abstract Details
Purpose:
To report late postoperative calcification of a combined hydrophilic–hydrophobic acrylic intraocular lens (IOL) as well as the clinical consequences and laboratory characteristics.
Setting:
Department of Ophthalmology, Gazi University School of Medicine, Ankara, Turkey.
Methods:
Two hydrophilic-hydrophobic IOLs (Acriva UD 613, VSY Biotechnology, The Netherlands) with calcification were explanted from patients who underwent pars plana vitrectomy surgery with silicone oil tamponade for retinal detachment. One patient had a combined phacoemulsification and pars plana vitrectomy with silicone oil tamponade and IOL opacification occurred in 6 years. Other patient underwent pars plana vitrectomy with silicone oil tamponade one year after phacoemulsification. IOL calcification happened in 3 years approximately. Explanted IOLs were analyzed at David J Apple International Laboratory, University Eye Clinic Heidelberg, Germany. Structural analysis (light microscopy and histological staining) was performed to the explanted IOLs.
Results:
Gross examination of IOLs has shown that the optic of each IOLs was partly opacified. Each IOLs separated into two parts and each part was stained with Alizarin Red which stains free calcium and certain calcium compounds, or van Kossa staining that can identify calcium deposits within the IOL material. In each case Alizarin Red staining of the surface was clearly visible indicating calcium deposits on the IOL surface and van Kossa staining method clearly revealed calcium deposits below the surface of the IOL. Significant vision loss caused by IOL calcification was restored after explantation in both cases.
Conclusions:
We have demonstrated two cases of hydrophilic–hydrophobic acrylic IOL calcification in patients who had pars plana vitrectomy with silicone oil tamponade. Calcium deposits below and on the surface of the IOL could be revealed by histological staining. Surgeons should be aware of this complication following vitrectomy with silicone oil in patients with combined hydrophilic–hydrophobic acrylic IOLs.
