A method of injecting a first viscous fluid into a target tissue simultaneous with aspirating a second viscous fluid from the target tissue is disclosed. A surgical system is provided that is capable of supplying pneumatic pressure and vacuum. A first viscous fluid is injected into the target tissue using pneumatic pressure from the system. A mode of operation of the system is changed to provide vacuum and pneumatic pressure. The second viscous fluid is aspirated from the target tissue using vacuum from the system, and the pneumatic pressure remains substantially constant during aspiration. An improved foot pedal for controlling the simultaneous injection and aspiration of viscous fluids is also disclosed.

[ What is claimed is:] [1.]1. A method of injecting a first viscous fluid into a posterior segment of an eye simultaneous with aspirating a second viscous fluid from said posterior segment, comprising the steps of:providing a surgical system capable of supplying pneumatic pressure and vacuum;injecting said first viscous fluid into said posterior segment using pneumatic pressure from said system;changing a mode of operation of said system to provide vacuum and pneumatic pressure; andaspirating said second viscous fluid from said posterior segment using vacuum from said system;wherein said pneumatic pressure exhibits a decrease of about twelve percent or less during said aspirating step.
