Anterior segment optical coherence tomography in a case of intraocular lens opacification

Abstract

Opacification of intraocular lens (IOL) is one of the uncommon causes of delayed decrease in vision postcataract surgery. It occurs more commonly with hydrophilic IOLs and less with hydrophobic IOLs. Here, we present a case of an 81-year-old lady, who came 7 years after an uneventful phacoemulsification with decrease in vision in her left eye (LE). Slit-lamp examination revealed an opacified IOL with a grossly normal posterior segment. Anterior segment optical coherence tomography (ASOCT) revealed a band of hyper reflectance on the anterior and posterior surface of IOL with a clear zone in between. She underwent IOL exchange with consequent vision improvement.
