A new high precision fingertip controlled aspiration device for extracapsular cataract surgery.
The electronically foot-switch controlled irrigation/aspiration instruments have several disadvantages due to the big 'dead space' between the pump and the aspiration cannula. A new high precision fingertip controlled aspiration system is described. A specially designed ball valve connects the aspiration cannula directly to the vacuum reservoir, thereby almost eliminating the dead space. The system is nonelectric, it has no moving parts, it is easy to operate and highly cost efficient.
