Brown Discoloration with Abbott Medical Optics (AMO) Intraocular Lens (IOL)

HSA would like to update healthcare professionals of eight incident reports of brown discoloration occurring with the Abbott Medical Optics (AMO) intraocular lens (IOLs) that were detected post-implantation. The affected IOLs are AMO Sensar 1-Piece IOL, Model AAB00 (“AAB00 lens”) and AMO Tecnis 1-Piece IOL, Model ZCB00 (“ZCB00 lens”).
