2831: opening a collapsed bag for the IOL

Close-up view of an eye during a surgical procedure, showing a collapsed bag ready for intraocular lens (IOL) placement after lens removal. Text prompts the viewer to consider how to open the bag.

Opening a collapsed, fibrosed capsular bag months after cataract extraction requires meticulous viscodissection and controlled fibrosis release. A dispersive viscoelastic is first injected to deepen the anterior chamber and gently separate anterior capsular leaflets. A sharp needle or micro-scissors can be used to create a small capsular opening, followed by careful enlargement with capsulorhexis forceps. Dense capsular fibrosis may require radial relaxing cuts to restore bag contour. Progressive viscoelastic injection helps reopen the bag and define the equator, allowing safe in-the-bag IOL implantation while minimizing zonular stress and posterior capsular rupture risk.
