The IOL scaffold technique is where the IOL is implanted prior to removal of the last bits of the cataract. This is sometimes done in cases where the posterior capsule is open in order to prevent vitreous prolapse and descent of nuclear pieces. It can also be used in cases where there is fluid misdirection so the capsular bag is flattening like previously shown. In this challenging case, the IOL is implanted prior the removal of the last bits of nucleus in order to provide a wider margin of safety. This is a technique that you must know because one day it will be a lifesaver.
