BLOG: IOL scaffold for IOL exchange in posterior capsular defect

The technique of IOL scaffold for IOL exchange was previously described by us, wherein the faulty IOL is levitated from the capsular bag into the anterior chamber followed by placement of another corrective foldable IOL into the bag. This technique can also be performed for cases with posterior capsular defect.

The video demonstrates the technique of performing an IOL scaffold for IOL exchange in a case with open posterior capsule. The previous surgeon had placed a one-piece foldable IOL in the sulcus that led to concurrent episodes of inflammation and pain. The vitreous strands were also seen protruding into the anterior chamber. Fluid infusion was introduced inside the eye with the trocar anterior chamber maintainer, and limited vitrectomy was done in the anterior chamber. The one-piece IOL was levitated into the anterior chamber, and a new three-piece IOL was injected beneath the one-piece IOL in a way that the haptics of the three-piece IOL were directed toward their placement in the sulcus. The one-piece IOL was cut with the IOL cutting scissors and explanted outside the eye.
