An analysis found a slight predominance of late in-the-bag IOL dislocations in men. Capsular tension rings may be a protective factor against dislocation. Late in-the-bag IOL dislocation has a ...

A capsular tension ring (CTR) can distribute zonular tension evenly at the capsule equator, keeping the capsular bag stretched open during nucleus manipulation. It may prevent vitreous prolapse ...
