Closed-chamber haptic reexternalization for posteriorly displaced sclerotomy and inadequate haptic tuck in glued posterior chamber intraocular lenses

摘要

The glued posterior chamber intraocular lens (PC IOL) requires externalization of a sufficient length of both haptics to obtain an adequate intrascleral tuck, which is vital for stable IOL fixation. One cause of a decreased length of externalized haptic may be a sclerotomy that is inadvertently placed posteriorly. We describe a technique to handle this situation by creating a fresh sclerotomy anterior to the first one, followed by internalizing the haptic and reexternalizing it through the new sclerotomy.
