Abstract
Intraocular lens (IOL) explantation after uneventful cataract surgery is rare but associated with the potential risk of complications. In previous years, the main causes of IOL explantation were pseudophakic bullous keratopathy (PBK), uveitis-glaucoma-hyphema syndrome, endophthalmitis, and cystoid macular edema. The improvement in phacoemulsification surgery goes in tandem with higher patient demands and expectations of the surgery. Therefore, in recent years, incorrect lens power and neuroadaptation failure to multifocal IOLs are also well-recognized indications for IOL explantation and exchange. IOL opacification, although it was an epidemic in the past especially associated with certain IOL models, is currently still occurring even with some new IOL models. In this review, the main reported IOL explantation techniques are explained as well as the outcomes of explantation surgeries according to the reason for explantation.KeywordsIntraocular lens exchangeIntraocular lens dislocationLens opacificationExplantation surgeryMultifocal intraocular lenses
