Two patients complained of blurred vision approximately 6 months after having combined vitrectomy and phacoemulsification with implantation of a C-flex 570C hydrophilic acrylic intraocular lens (IOL). Multiple granules were noted on the anterior surface of the IOLs in both patients. Intraocular lens exchange was performed in both eyes, and the explanted IOLs were sent for histopathological analysis. Scanning electron microscopy confirmed the presence of cracks and granules on the IOL surfaces and energy-dispersive x-ray spectroscopy demonstrated calcium deposition. Based on the calcification pattern on the anterior surface of the IOLs, 2 additional cases of opacification were identified under slitlamp examination.
