title: Intraocular lens scaffold to facilitate intraocular lens exchange.
abstract: We describe a technique of intraocular lens (IOL) exchange in patients with post-refractive surgery IOL power error or patients who are dissatisfied with the optical performance of the IOL. The technique involves the presence of 2 IOLs in the eye: the offending IOL, which is manipulated out of the capsular bag into the anterior chamber, and the corrective IOL, which is inserted into the bag. The anteriorly elevated IOL is transected with the IOL cutting scissors, while the corrective IOL acts as a scaffold for the posterior capsule. The technique provides continuous distension of the bag with the IOL, which prevents damage to the posterior capsule and acts as a barrier to vitreous prolapse in cases of an open posterior capsule; it also prevents slippage of the optic during transection of the IOL being removed.
