A Case of Hydrophilic Acrylic Intraocular Lens Opacification in a Patient with Proliferative Diabetic Retinopathy

Purpose: To report a case of hydrophilic acrylic intraocular lens (IOL) opacification in a patient who underwent vitrectomy and cataract surgery for the treatment of diabetic retinopathy. Case summary: A 54-year-old female complained of blurred vision for 15 months after having combined vitrectomy and phacoemulsification with IOL (Rayner? Superflex? 620H) implantation for the treatment of high-risk proliferative diabetic retinopathy. On slit-lamp examination, IOL opacification was evident. IOL exchange was performed and the explanted IOL analyzed. Scanning electron microscopy (SEM) revealed the presence of translucent granular deposits on the anterior subsurface of the IOL. Energy dispersive X-ray spectroscopy (EDS) demonstrated calcium and phosphate deposition within the IOL optic. J Korean Ophthalmol Soc 2012;53(8):1172-1176
