ABSTRACT:
In the surgical art of extracapsular cataract extraction, the lens capsule of the eye is irrigated and aspirated for cortex removal through use of a simple, inexpensive system of circulation of an irrigating solution, accompanied by automatic filtering of the aspirated material out of the solution such that the filtered liquid may be reintroduced. Means are included to produce unidirectional flow, and a manually operable bypass feature provides for safety and operator control of the entire procedure to assure accuracy, efficiency, exactitude and the best possible end results. The system is kept filled with the liquid solution in substantial absence of air therewithin.
