Anterior Chamber Collapse
In this case, we ran out of fluid and had the bottle changed while we placed the intraocular lens (IOL). When we started back to remove the ophthalmic viscosurgical device following placing the IOL (and the bottle change) the anterior chamber collapsed. As we later discovered, the RN who changed the bottle clamped the tubing so that no fluid could flow into the chamber. You should remember to confirm that the fluid is flowing before starting aspiration.
