Microsurgical instruments have revolutionized how ophthalmologists perform procedures. One procedure that has gained particular benefit from the evolution of ophthalmic tools is IOL explantation. I work at a high-volume center and perform more than 1,000 procedures a year—about 5% of which are IOL explantations for several reasons.
Initially, lenses explantation were primarily anterior chamber IOLs, needing removal secondary to pseudophakic bullous keratopathy, uveitis-glaucoma-hyphema syndrome, or cystoid macular edema.1
Since posterior chamber IOLs have become more common, indications for explantation or exchange has shifted to IOL decentration, incorrect power calculation, intolerable visual symptoms such as glare or halos, and opacification.2
