[A simplified drainage/irrigation system for extracapsular cataract extraction].

A simplified irrigation/aspiration system has been developed by the author in cooperation with the Klein company of Heidelberg. The suction is produced by connecting the instrument to a commonly used aspirator. The aspiration force is regulated by means of a foot-pedal, which regulates the amount of "bypass air" delivered through a special tube connected to the irrigation/aspiration handpiece. This simple i/a system represents a low-priced alternative to other systems already on the market.
