Refractive Nightmares Revisited: Calcification of a Multifocal Intraocular Lens.

Abstract

Cataract is the leading cause of reversible blindness and visual impairment worldwide. Although cataract surgery using phacoemulsification and intraocular lens (IOL) implantation is one of the commonest surgical procedures, IOL opacification remains a potential complication that can affect the visual outcome of the operation. A 50-year-old female patient presented to our clinic complaining of glare and blurry vision in her right eye over the previous 6 weeks. She had undergone bilateral refractive lens exchange elsewhere 9 months earlier. Her unaided distance visual acuity was 8/10 in the right eye and 10/10 in the left. On slit-lamp examination, we observed the presence of in-the-bag, multifocal, hydrophobic acrylic IOLs bilaterally. Specifically, calcified deposits within the substance of the IOL were observed. To our knowledge, this is the first case of spontaneous calcification of a hydrophobic multifocal IOL and all cataract/refractive surgeons should be aware of this rare complication.
